Pigeons are ordinary inhabitants of cities. They nest under the roofs of buildings and multiply rapidly. Chicks appear in March-July. Where pigeons live and feed, a lot of bird droppings accumulate, which can be a source of disease. Pigeons are the source of three human diseases: histoplasmosis, cryptococcosis and psittacosis.
Histoplasmosis- pigeon poop danger
Histoplasmosis is a disease caused by fungi that grow on pigeon droppings or in the soil and is not transmitted from person to person. If a person cleaning surfaces from pigeon droppings accidentally inhales enough fungi, then he will get histoplasmosis. If you only clean the window sill from pigeon droppings from time to time, then you have nothing to fear.
10 days after contact with fungi, weakness may appear, fever and chest pain, but most begin asymptomatically. The highest risk is in people with weak immunity: HIV-infected or suffering from cancer.
Cryptococcosis- pigeon poop danger
Cryptococcosis, like histoplasmosis, is caused by fungi that grow in bird droppings or in the soil. Completely healthy people rarely get cryptococcosis, even if they inhale a large number of mushrooms. Almost always people with immune defects suffer from this infection, 85% of people with cryptococcosis are HIV-infected patients.
Ornithosis - the danger of pigeon droppings
Ornithosis (also known as psittacosis or parrot disease) is a bacterial infection that most commonly affects parrots and parrots, but occasionally occurs in other birds, including pigeons. A person can become infected with ornithosis if he accidentally inhales particles of dried droppings of a sick bird.
10 days after infection, a sick person develops weakness, fever, headache, rash, chills and pneumonia. Ornithosis is treated with conventional antibiotics.
The vast majority of those infected say they played with sick poultry before getting sick, so pet keepers, pet store employees, veterinarians, and people with weak immune systems are at risk. Ornithosis is not transmitted from person to person.
How to properly clean bird droppings?
In a normal situation, for example, when you just need to wipe the window sill from dirt, it is almost impossible to get infected. Simple protective measures are sufficient: wear rubber gloves and work clothes.
If more contaminated surfaces are to be cleaned, such as attics, roofs, or any other pigeon habitat where a lot of bird droppings have accumulated, then appropriate work clothes, rubber boots, gloves and respirators should be worn, especially for immunocompromised people. Wash your hands thoroughly before eating and after finishing work.
If you want to remove dirt by pouring water under pressure from a hose, then enclose the space with a dense film so that splashes with dirt particles do not scatter into different sides. It is convenient to pour water over contamination before cleaning - this way, infected dust will not rise into the air, and you will reduce the risk of inhaling fungi and bacteria.
Instead of pressurized water, you can choose more safe way Cleaning: Pour the droppings with water, wait until they get wet, and then shovel it into heavy polyethylene bags. Litter in closed bags can be disposed of as normal garbage. And in order not to endanger yourself in the future, clean this area more often so that the litter does not accumulate.
Immunocompromised people (for example, people with AIDS or cancer) should not take part in bird droppings cleaning, as they are at a very high risk of infection.
On which balconies do pigeons like to settle?
Pigeons love space, wide railings, heaps of boxes and furniture on open balconies where they can build a nest. The presence of water and food on the block, as well as silence.
How to scare away birds from the balcony?
- Birds do not like noise, so the speakers with music should be placed as close as possible to the balcony door or window.
- Cut into strips of food foil, the rustling and shine will scare away the pigeons for a while.
- Hang CDs, birds don't like their glare.
- Lubricate the ledges on which birds like to sit, grease with petroleum jelly.
- Cut off the bottom plastic bottle, then along, not reaching the neck, cut a fringe 2-3 cm. Place on the floor of the balcony (octopus) and press on the neck. Plastic gives glare, like from water, which scares away pigeons.
- Place the Stuffed Raven, it will scare away for several months, but then the pigeons will get used to it and it will be possible to reuse the stuffed animal next season.
- If it seems unaesthetic to you to hang a beam with a net, then this method will be completely invisible: at a height of 5 cm from the railing, pull the fishing line. It is invisible, but will prevent the pigeons from landing.
- You can also scare away pigeons with the help of pungent odors: spread moth balls on the balcony or install an automatic air freshener with a pungent odor.
- Mustard effectively affects the sense of smell of birds, only periodically it will have to be poured.
- From electronic repellers, it is advisable to choose Ultrasonic (not sonic), and make sure that the frequencies used in the device are not audible to you personally.
If a pigeon's nest with eggs appeared on the balcony?
It is useless to throw away, the pigeons will build a new one. It is better to put a dummy instead of eggs, for example, chalk. After a while, the birds will realize that the chicks have not hatched and will leave this place forever. Pigeons do not return to places unfavorable for breeding.
An article about how to wipe bird droppings from a car body - cleaning products, subtleties of work, tips. At the end of the article - a video about bird droppings on the paintwork of the car.
The content of the article:
If you do not wipe bird droppings from the car body for a long time, this seemingly harmless speck can easily turn into a big nuisance for the car. And the point here is not at all that admiring the feces of a feathered tribe is not aesthetically pleasing, and scrubbing is unpleasant. The problem lies in the literal sense of the word much deeper: litter easily destroys the paintwork.
Consequences of pollution
In the event that bird droppings are not removed from the car body soon, it begins to enter into chemical interaction with the paint layer. As a result, the following situations are possible:
- discoloration of paint under the litter;
- dissolution of the film layer;
- paint swelling;
- the appearance of cracks in the paintwork of the body;
- formation of bubbles on the paint layer.
The main reason for the forced increased attention of motorists to bird droppings on the car body lies in one unpleasant feature of birds.
The product of the vital activity of birds differs significantly from the excrement of other species of living beings. The excretory system of a bird does not have such an "option" as urination. This means that nitrogenous compounds, which are produced by almost every living organism and which in most animal species are excreted as a solution of urea in urine, are excreted in the form of uric acid in birds. Uric acid makes up a large proportion of bird excretions and appears as a white substance.
Thus, bird droppings are a mixture of chemically aggressive organic acids, which are extremely slightly soluble in water, but at the same time easily corrode the varnishes and paints that cover the car body.
It is precisely because of the weak dissolution in water that it is impossible to remove already dried droppings from the machine simply with a damp cloth. Worse, water does not dissolve the compound, but activates the destructive action of the acid, which without moisture is generally not dangerous.
Also, do not hope that the bird's "hello" will simply dry out in the sun and lose its aggressive qualities: heat only exacerbates the problem, activating the rate of flow of corrosive and other destructive processes.
Since the hot sun and atmospheric moisture increase the destruction, biggest problems bird droppings on the body of a car delivers to its owner in a hot and humid climate. But this does not mean that in other conditions the problem does not exist: it just develops more slowly, but still leads to the same result.
Do not forget that birds, in order to facilitate digestion, swallow small stones throughout their lives, which help to grind food in the stomach. These pebbles are also excreted with litter, and in addition to chemical aggressiveness, excrement is also abrasive.
Is there protection
Unfortunately acid resistant protective coatings for the car body does not exist today. However, wax and protective polymer compounds can be used, which for some time can protect against aggressive acidic compounds.
One hundred percent forget about the problem will not work, but still, the use of these tools forms on the surface machine body moisture-repellent film that prevents the adhesion of contaminants of any nature. Thus, the motorist gets some time in order to get rid of pollution without harm to the coating.
It is also important to remember that the applied protective wax or polymer layer is erased quickly enough, and it must be renewed regularly.
In order to reduce the likelihood of getting pollution, you should not park your car under trees, especially where there are bird nests, and under wires, a favorite "roost" for pigeons and other city feathered residents.
If circumstances often force you to park under trees, it is better to think about purchasing car cover. It may seem too expensive and impractical, but believe me that dried droppings can deliver much more to the car owner. more problems than the cost of purchasing a cover and the need to close the car with it.
Removing pollution
The main safety rule automotive coverage- get rid of bird "surprises" as soon as possible. The main task is to have time to do this before the acid enters into a chemical reaction with the paint under the influence of moisture and the burning sun.
Getting started, you should remember an important rule:
Bird droppings are often breeding grounds for disease-causing bacteria and can cause infection with infectious diseases. Therefore, you need to remove it from the car only with gloves. It is better if the gloves are disposable - after finishing work, you can simply pack them in a bag and throw them away, and wash your hands thoroughly or wipe them with a disinfectant.
There are several ways to remove bird droppings. Which one to choose depends on the degree of pollution and its prescription.
Soft fabric
If the litter is very fresh, it can be carefully removed with a damp soft cloth. At the same time, do not forget that the composition of the pollution is abrasive, which means that if you rub it, you can easily leave scratches on the paint.
Carefully collect dirt with a rag and remove from the body. The remaining fragments must be washed off with water and gently wipe the surface clean.
Ordinary pure water
It is used in the event that the litter has already dried up, but the pollution is no more than a few days, and the acid has not had time to react with the surface.
You need to take wet gauze folded 6-8 times or a piece of soft rag, put it on the pollution and pour water on top. The fabric will hold water, preventing it from spreading over the surface of the body. At the same time, moisture will penetrate the dirt and soften it without damaging the paint.
When the litter is softened, it must be carefully removed with the same rag. In order not to scratch the surface, the remaining abrasive particles can be removed with a special cleaning clay, which is used to clean varnished surfaces.
Also good results with fresh litter gives a simple soda: The carbonic acid contained in this drink carbonizes the acidic compounds, and they break down, becoming harmless to the paint layer.
Alkaline compounds
Acid is “not friendly” with alkali, so you can use ordinary baking soda or household soda to remove litter, dissolving it in clean water. The resulting solution should be used in the same way as plain water in paragraph 1. You may have to wait about half an hour until the composition softens the pollution.
Any cleansers containing alkaline compounds will also work.
Do not forget that the soda solution is also abrasive, so, again, you should not rub the stain.
A mixture of water and isopropyl alcohol
IPA (isopropyl alcohol) is mixed with distilled water in equal proportions. In relation to acid, alcohol works as an adsorbent, and this property is enhanced in combination with water. After applying the composition to the contamination, you should wait two to three minutes until the solution reacts with the litter, then rinse everything off with clean water.
In addition to a self-made solution, you can use any household cleaners based on isopropyl alcohol.
All-Purpose Multipurpose WD-40 Compound
The product is sprayed on pollution, thoroughly impregnating it. After 5-10 minutes, you can remove the droppings with a disposable napkin or a piece of rag. The manufacturers of this all-purpose cleaner indicate that one of the ways to use the product is to clean paintwork car from bird droppings. At the same time, the composition itself is neutral to the paint layer, does not destroy it.
Dimexide
A folk remedy for bird droppings is also called ordinary dimexide - a drug that can be purchased at pharmacies. Being a strong alkaline compound, it also handles this type of dirt well. But in the case of its use, it should be remembered that dimexide itself is aggressive and can ruin the varnish film. Therefore, you need to apply it on the stain in a small amount and remove it quickly, without overdoing it.
Coca Cola
This amazing drink is generally capable of much.: No wonder housewives got the hang of using it to remove old dirt. In the case of litter, Coca-Cola also does not fail, although it probably will not be as effective as special means to clean the body. At the same time, she has one advantage over the same dimexide - she is not so dangerous for the varnish layer of the body.
Not only the body!
If the birds, by some chance, spared the body of the car, but at the same time soiled Windshield, you should also take care of the issue of cleaning as soon as possible. The litter is equally aggressive and glass surfaces, you need to remove it from the windows as quickly as from the body.
If, after the bird droppings are removed from the car body, small scratches, it is worth carrying out abrasive polishing of the surface. The main thing to remember when receiving a “bird hello” on the hood is that you should not delay cleaning. The later you get down to business, the more difficult the process will be!

Ecology of life. Health: Today once again I watched how children squeeze pigeons and crawl in their droppings, joyful and dangerously careless. So I decided to give a warning...
People perceive pigeons in different ways: some - for (a symbol of peace, love, without human support they will die); others - against ("flying rats", importunate, unscrupulous, carriers of infection).
Today once again I watched how children squeeze pigeons and crawl in their droppings, joyful and dangerously careless. Therefore, I decided to warn you that city pigeons can pose a serious threat to your health, as they are carriers of many infectious diseases. Even worse, pigeon feces are a source of infection and inhaling them is no less dangerous than direct contact with pigeons.
And one pigeon is 12 kilograms of feces per year! This seemingly harmless bird can be a carrier of 90 pathogens of many diseases, including ten zoonotic infections (zoonoses), that is, those that are transmitted to humans from animals.
Diseases transmitted from animals to humans are called zoonoses. The causative agents of these diseases can be protozoa, fungi, bacteria, chlamydia and viruses. Individual susceptibility to them in each person depends on the state of the immune system, age, health status and other factors.
ornithosis
Ornithosis (also known as psittacosis or parrot disease) is a bacterial infection that most commonly affects parrots and parrots, but occasionally occurs in other birds, including pigeons. A person can become infected with ornithosis if he accidentally inhales particles of dried droppings of a sick bird. Ten days after infection, a sick person develops weakness, fever, headache, rash, chills, and pneumonia.
Chlamydia psittaci was found in 52.6 percent of the captured pigeons. Infection from this bacterium results in symptoms such as mild flu-like illness and severe pneumonia. Most often, such diseases are recorded in spring and autumn, this is due to a decrease in immunity in young birds and their susceptibility to diseases.
Farm birds (ducks, turkeys), house birds (parrots, budgerigars, canaries and other small songbirds) and especially urban pigeons, the infestation of which ranges from 30% to 80%, are of the greatest epidemic importance.
The causative agent of ornithosis, unlike other chlamydia, is capable of long-term preservation in environment: retains viability at a temperature of 37 ° C for up to 2 days, at 4–6 ° C - for a week; after lyophilization, the pathogen persists for 5 years or more.
The incubation period for ornithosis ranges from 5 to 30 days (usually 10-12 days). At the beginning of the disease, fever with chills and increased sweating, pain in the throat, muscles and joints are characteristic. Conjunctivitis, a thickened tongue with possible imprints of teeth along the edges, often hepatolienal syndrome, emotional disturbances (excitation, irritability, tearfulness) are noted. From 3-4 days of illness, laryngitis or bronchitis, interstitial or small-focal pneumonia with poor physical data develop.
With a special examination for ornithosis in different countries(Bulgaria, Holland, USA, Germany, etc.) found that 10-20% of acute pneumonia has ornithosis etiology. In Moscow, ornithosis was detected in 18.4% of patients with acute pneumonia, in St. Petersburg - in 19.6%.
Doctors note that although seasonal outbreaks of ornithosis are not observed, they still get sick more often in the cold season. This is due to a number of reasons, one of which is the similarity of the symptoms of ornithosis with the symptoms of SARS and common colds, which makes it difficult to make a diagnosis. In addition, in the cold, pigeons stray into large flocks and, therefore, the infection spreads faster. One sick bird can infect an entire flock. And then this sick flock scatters into the city's garbage containers, which are often placed near places where children walk.
Thus, many places appear around the city where you can pick up ornithosis and other diseases. Ornithologist Natalya Obukhova says in this regard that garbage and dirt in cities contribute to a rapid increase in the number of pigeons. No one monitors the bird population in Moscow, and yet the incidence of ornithosis among Muscovites is an order of magnitude higher than the same rabies.
A person is more resistant to ornithosis, but the course of the disease is severe (severe headaches, fever, weakness of the whole organism). It is very similar to influenza and acute respiratory diseases. Children catch the infection much more often than adults, as they can touch birds while playing with them. Children need to be supervised and explained to them what troubles can be due to communication with birds.
salmonellosis
Salmonellosis is an intestinal disease caused by numerous pathogens from the genus Salmonella. The main sources of infection are animals, occasionally people. The asymptomatic course of the disease has been established in many species of farm animals, cats, dogs, rodents, and birds.
"The disease does not pose a danger to humans, provided that standard personal hygiene measures are followed and direct contact with a sick bird is excluded. The causative agents of bird flu and psittacosis (an infection that can be transmitted to humans) have not been identified," the committee said.
Common clinical symptoms in all animals include diarrhea, vomiting, and fever. The infection can progress towards dehydration, weakness, and sometimes, especially in the case of very young or very old individuals, death. In severe cases, there may be high fever, septicemia (blood poisoning), headaches, and an enlarged, painful spleen. Focal infections can occur in various organs, including the heart, kidneys, ligaments, pia maters surrounding the brain and spinal cord, and connective tissues surrounding all bones in the body.
The incubation period is 12-36 hours. Salmonella is transmitted by eating food contaminated with droppings. Isolation of bacteria by a sick person can last from several days to several weeks.
Campylobacter jejuni
Until 1972, when a reliable method for their isolation was developed, Campylobacter jejuni was considered pathogenic only in animals (sheep and cattle). However, further research showed their danger to humans. According to the FDA (U.S. Food & Drug Administration) - Office for Food Products and US Medicines, Campylobacter jejuni is currently the most common cause bacterial diarrhea in humans. Moreover, C.jejuni causes more cases of disease than Shigella spp. and Salmonella spp. taken together.
They are present in most representatives of this bird population and turn out to be more harmful than the well-known Salmonella. Outdoor pigeons serve as reservoirs for the production and growth of varieties of bacteria, hence they can lead to harmful diseases.
Campylobacter jejuni, which was present in 69.1 percent of pigeons caught, causes abdominal pain, diarrhea, fever and general malaise in infected humans. The thermophilic species of Campylobacter are considered the main causative agents of acute diarrheal diseases around the world - and more often than salmonella."
Newcastle infection
With a Newcastle infection, a sick pigeon can also infect a person through the mucous membrane of the eye. True, for a person it is not as dangerous as for a bird, it occurs in the form of a cold, conjunctivitis with swelling of the parotid lymph nodes for one week. Affected may be mainly poultry workers and laboratory workers.
paramyxovirus
So, pigeons are a natural carrier of paramyxoviruses that can spread to poultry: chickens, turkeys, geese, ducks, pheasants, guinea fowls, and even ostriches, emus and rhea. The virus is stable and is shed pigeon droppings, which can exist for about 3-4 weeks. And this means that your soles and even clothes can be vehicle for viruses.
Because paramyxovirus, although not deadly to humans, is still capable of causing very unpleasant diseases in humans. Alexey Alekseenko, an assistant to the head of the Rosselkhoznadzor, noted that this infection can enter the human body through the mucous membrane of the eye, which will cause symptoms resembling a cold and conjunctivitis with swelling of the parotid lymph nodes within one week. It seems nothing special, but not pleasant enough.
Surface acariases
In addition to the scabies mite, skin lesions in humans can be caused by mites that live on animals and birds (dogs, cats, rats, pigeons), on cereals, in grass and straw, pillow feathers, etc. Most often, people are affected by the scabies mite of horses, rat, chicken and pigeon ticks. The last three types can cause mass destruction in families, hostels. Unlike scabies caused by Sarcoptes hominis, these types of mites do not burrow into the stratum corneum and do not form passages, but only inflict bites that cause severe itching and the formation of papules or blisters in their place, in the center of which punctate hemorrhage or a more intense color is often visible. , serous or hemorrhagic crust, vesicle (bite mark). Elements of a skin rash are found most often in places of close contact of the skin with linen. Ticks are found in underwear and bedding, indoors.
Avian tuberculosis, which can also infect humans, is caused by Mycobacterium avium, similar to the classic human tuberculosis mycobacteria. Infection occurs through water and food contaminated with bird down.
Mycobacterium infects the human respiratory and lymphatic system, causing local infectious wounds. In people with immunodeficiency, the process is generalized, and death is possible. Mycobacterium avium is often resistant to antibacterial and anti-tuberculosis drugs, which makes it difficult to select therapy.
Histoplasmosis
Histoplasmosis is a disease caused by fungi that grow on pigeon droppings or in the soil and is not transmitted from person to person. If a person cleaning surfaces from pigeon droppings accidentally inhales enough fungi, then he will get histoplasmosis. If you only clean the window sill from pigeon droppings from time to time, then you have nothing to fear. 10 days after contact with the fungi, weakness, fever and chest pain may appear, but most of the disease begins asymptomatically. The highest risk is in people with weak immunity: HIV-infected or suffering from cancer.
Cryptosporodiosis
A disease caused by a protozoan (genus Cryptosporidium). In birds, the pathogen affects the pulmonary system, and in humans, the gastrointestinal system. Infection occurs by the fecal-oral route - through the consumption of foods contaminated with oocysts. The disease is manifested by nausea, vomiting, diarrhea (watery stools up to 15 times a day), abdominal pain, weakness. Recovery usually occurs within 10 days.
Cryptococcosis
Cryptococcosis, like histoplasmosis, is caused by fungi that grow in bird droppings or in the soil. Completely healthy people rarely get cryptococcosis, even if they inhale a large number of mushrooms. Almost always, people with immune defects suffer from this infection, 85% of people with cryptococcosis are HIV-infected patients.
In a normal situation, for example, when you just need to wipe the window sill from dirt, it is almost impossible to get infected. Simple protective measures are sufficient: wear rubber gloves and work clothes. If more contaminated surfaces are to be cleaned, such as attics, roofs, or any other pigeon habitat where a lot of bird droppings have accumulated, then appropriate work clothes, rubber boots, gloves and respirators should be worn, especially for immunocompromised people. Wash your hands thoroughly before eating and after finishing work.
Allergic alveolitis
Allergic alveolitis is one of the main zoonotic diseases of birds. The disease can occur in acute, subacute and chronic forms. Clinical signs of the disease are hypersensitivity to feathers, dander, or dung dust due to reduced lung capacity. There is inflammation of the alveoli, the lung structures responsible for air exchange.
The acute form of the disease is usually initiated by excessive contact of a sensitive person with certain circumstances, for example, cleaning the dovecote, attic. Symptoms occur almost immediately and include cough, difficulty breathing, fever, and chills. If at this stage the person ceases contact with the bird, then the symptoms disappear and the person does not need special treatment.
These insects can get into the apartments of our residents. In addition, pigeon litter contains a lot of uric acid. This is also very harmful substance. The fact is that birds do not excrete urea, but uric acid, which, evaporating, primarily has a negative effect on the upper respiratory tract. It irritates them, and in asthmatics it can even cause attacks.
4. Do not feed pigeons from balconies.5. Inspect attics sanitizing them from pigeons.
6. Remove pigeon droppings in a respirator and overalls! Be wary of pigeon droppings (and the ground that can be contaminated with it) no less than the birds themselves.
7. Stay away from sick pigeons. If you notice liquid droppings or at least one of the birds with such symptoms: disheveled, lethargic, with crooked fingers or paws, with faded or glued, as if wet, plumage, with split feathers, as if they were trimmed with small scissors, then immediately leave ! You shouldn't tempt fate.
8. Don't pick up sick pigeons. They are usually much less mobile than healthy ones, live alone, without a pack (which drives them out due to the danger of infection), and look quite pathetic. Often, precisely for this reason, they fall into the hands of children and old women with a good heart.
9. Of course, you will enrich your shoes and clothes with viruses if you climb into the attic, where city pigeons live, you will move boxes and other things there. Water from puddles, asphalt on the road, polluted by birds - all this is the source of the virus.
British government services recommend that when a dead pigeon is found, do not take it with your bare hands - it is advisable to pack it in a double bag and throw it in the trash or bury it (without a bag) in the ground. If you leave this work to your janitor, advise him to put on disposable gloves, which you don’t mind throwing away later. Otherwise, the janitor himself will become the carrier of the infection. published
Garden paths, sidewalks, patios with a surface of paving slabs is the most popular holiday destination in every household, it is the place where most people enjoy their time with family, friends and relatives. However, we are not always on the patio, and during our absence, birds can be located on the wires and protruding surfaces of the patio, resulting in bird droppings found in the morning, and sometimes a lot. Sometimes, birds can bring various berries, and other types of food that can easily get dirty. concrete paving slabs in the allotment. Fortunately knowing correct technique cleaning, you can easily get rid of bird droppings and third-party stains on paving slabs.
Instructions for cleaning bird droppings from concrete paving slabs:
Necessary materials and tools: spatula or scraper (hard brush or broom with hard bristles), "Just Green", detergent soft action, plastic bucket, hot water, rag, garden hose, hose nozzle. First you need to clean up excess droppings with a spatula or scraper. Be sure to remove any excess droppings, and the same goes for third party trash. If laid sandstone paving stone, the use of a spatula is excluded.
Soaking stains on paving stones
Mix a small amount of Just Green cleaner or mild detergent in a bucket of hot water, stir until completely dissolved. Splash the mixture of water and detergent onto the bird droppings, then dampen a rag with the same cleaning mixture. Lay a rag soaked in the cleaning mixture on top of the bird droppings and leave it like that for an hour impact on paving slabs. Remember that you must perform this action out of sunlight, otherwise the rag may dry out and you will not get the desired effect.
scraping
Use a brush with bronze bristles (not metal) and scrub off particularly stubborn stains of bird droppings. Clean the paving slabs with a garden hose when you're done. Repeat the cleaning process paving slabs with another cleaning agent if the first one applied did not work well enough to meet your expectations.
washing machine high pressure
Using a high pressure washer. If all else fails to clean the paving slabs, use a high pressure washer set to low pressure to try and clean up the remaining bird dropping stains. This method must be treated very carefully and monitor the pressure, as well as the cleaning technique. The fact is that a high pressure washer can easily damage the integrity of laying paving slabs and mortar seams, if any. You need to check with a hardware store for the right power for paving slabs before inadvertently applying washing machine high pressure.
You must be careful about the detergents you choose, and especially chemical composition inside them. Test the cleaning solution on a less visible area of the tile to make sure the detergent is not discoloring the pavers. If so, use only hot water. You can use a construction cloth or tarp to cover the sidewalk area afterward to avoid re-cleaning.
