How to Clean Bird Poop off Concrete

Many enjoy the sounds of birds around their house, but you have to deal with the nuisance of bird poop and stains on your concrete walkways, patios, and driveways. If left uncleaned for long, they become more challenging to remove. Therefore it’s best to clean the stains before they dry up. The ideal approach is not to let the bird droppings build-up or solidify.

Bird poop on concrete may seem difficult to remove, especially if it has dried up, but using the suitable cleaning method will effectively remove bird poop without damaging the underlying surface.

The article below has discussed why cleaning bird poop is essential and the best ways to clean bird poop off concrete to ensure they remain stain-free and disinfected.

Why do you need to clean bird droppings?

Although bird droppings make a place look undesirable, there are more serious reasons why you should clean bird droppings from your concrete as soon as possible.

Corrodes concrete

A major concern with bird poop is its high acidity which erodes your concrete. The uric acid in bird droppings can penetrate the concrete surface through the pores, thus disintegrating construction materials and leaving cracks and stains. In addition, it may cause brick roofs to start leaking due to erosion.


Just like other animals, bird droppings contain what the bird eats. This includes worms, fruits, berries, and nuts, which give the bird poop their staining effect. The color from the fruits and berries soaks ad stains into the porous concrete surface.

Health hazard

Also, cleaning the bird poop is essential because of the harmful health hazards they cause. According to the Health and Safety Executive and, bird droppings can carry over 60 diseases. However, bird poop isn’t specifically dangerous on its own. But if left over a long time in large quantity, it can grow bacteria and fungi.

Among the most common is a yeast-like fungus called Cryptococcus, which causes Cryptococcosis, which affects the central nervous system. Ingesting and inhaling the fungus is also very dangerous for vulnerable people with already weakened immunity.

Breathing dust or drinking water containing bird droppings causes several diseases such as psittacosis.

Bird droppings can also cause Salmonella, a bacterial infection with significant diarrhea.

What is the best cleaner for bird poop?

There is no single best cleaner bird poop off. The product you use depends on the severity of the bird droppings and the surface type. Wet bird droppings are easier to clean off, while dried bird dropping may require more abrasive cleaners to deal with the stains and how much bird poop the concrete has absorbed. Below is a list of our best commercial bird poop cleaners and DIY cleaners you can make with household items that work on most surfaces.

Commercial bird droppings cleaners

There are several commercial bird poop cleaners in the market at your disposal. These cleaners contain non-toxic enzymes formulated to clean, digest and deodorize bird droppings. Our favorite brand Poop-Off Bird Poop Remover Sprayer, has excellent reviews on effectively removing bird droppings from most surfaces, including concrete. It cleans out wet bird droppings and lifts and dissolves bird poop stains. It is non-toxic and biodegradable, therefore safe to use around plants.

Commercial organic concrete cleaners

If you are dealing with dried bird poop, the best cleaner is organic concrete cleaner. Organic cleaners consist of enzymes and bacteria that break down the bird poop stain. The best concrete cleaner should contain a bleaching ingredient or ammonia. Granular concrete cleaners are better since they provide additional friction when scrubbing the surface.

However, concrete cleaners are for unsealed concrete only. Do not use concrete cleaners on painted concrete surfaces as they can break down the paint and cause lifting. Some good concrete cleaners include:

  • Simple Green Oxy Solve Concrete and Driveway Cleaner: This environmentally-friendly concrete cleaner uses hydrogen peroxide to lift stains from concrete. You do not have to worry about this cleaner running off into your lawn and poisoning your vegetation with this product.
  • Zep Neutral pH Floor Cleaner Concentrate: This concrete cleaner is ideal for both sealed and unsealed concrete floors, as well as asphalt, brick, and stone. It lifts all kinds of stains, including bird poop and oil stains.

Baking soda

Baking soda is an excellent cleaner for small and mild bird poop stains.

Mix two tablespoons of baking soda, hot water, and a drop of liquid dish soap in a spray bottle. Allow the baking soda to sit on the stain for a few minutes, scrub it with a brush, and rinse it with clean water.

Baking soda also has abrasive particles that will help scour the stains off the concrete. Additionally, it is a natural deodorant that will leave your concrete free from bird poop odor.


WD-40 is great at loosening dried stains on most surfaces, including concrete.

First, spray the cleaner on the bird poop stain and allow it to sit for a while. Then, use a brush to gently scrub off any remaining residue and rinse the residue with a hose. WD-40 is very effective at removing bird poop on painted concrete as it is not abrasive.

Club soda/ Seltzer

Carbonated club water or seltzer water is ideal for removing bird poop from most surfaces. The carbonation degrades the uric acid in bird droppings, allowing you to wipe the mess away easily.

Pour the club soda on the bird poop stain and let it sit for 60 seconds. Do not let it sit for too long on concrete. Then rinse it off with clean water.

Do not use sugary sodas like cola.


Another effective way to remove bird droppings stains from hard outdoor surfaces is to use chlorine bleach.

Mix 3/4 cup of chlorine bleach, one gallon of warm water, and one tablespoon laundry detergent, then pour the solution on the dropping stains and let it sit for 15 minutes. The bleach solution will lift the stains and also disinfect the area. Then scrub the area with a nylon-bristled brush.

Alternatively, apply the solution at low pressure and allow it to soak for about five minutes before pressure washing the stained concrete. If the bird poop stains are major, use the solution in a pressure washer at low pressure.

Laundry or hand dishwashing detergent

Laundry detergent will help disinfect and clean the bird poop off your patio without damaging the concrete. Laundry detergent is great for painted concrete and wet bird droppings. It also helps settle suspended air-born particles that you could inhale and cause respiratory issues.

First, soak the area with the detergent for 15 minutes, then scrub or scrape the droppings area. Then wipe the area with absorbent wipes and table cloths.

Does vinegar clean bird poop?

White vinegar effectively cleans off bird poop, especially on smooth surfaces such as glass or painted metal surfaces. In addition, its acidity can break down the stains, making it easier to scrub off the stains.

Mix equal parts of white vinegar and warm water, then add one tablespoon of liquid hand dishwashing detergent in a spray bottle and spray this solution over the stained area. Allow the stain to soak the solution for a few minutes, and then use a nylon-bristled brush to scrub off the droppings.
