How to remove Bird Droppings from Concrete
First 60 seconds
The first sixty seconds decide how this turns out. Scrape away the excess bird droppings from the concrete, lifting solids off the surface without pressing them further in. The mix of uric acid and undigested seed is acidic enough to etch some finishes if left overnight, and highly porous and alkaline, so it can pull stains deep if not treated quickly.
What you'll need
- An enzyme cleaner
- White vinegar
- Dish soap
Step by step
- Gather your materials before you start — set out everything so you are not searching mid-treatment.
- An enzyme cleaner: saturate fully — enzymes need contact time to break down the residue.
- White vinegar: mix one part vinegar with two parts water.
- Dish soap: mix a few drops with cold water into a light suds.
- Rinse and blot dry with a clean cloth, then press with dry towels and change them until no more transfers onto the towel.
Do not do this
- Ammonia-based cleaners. Mixed with certain stains it can release harsh fumes or set protein.
- Chlorine bleach. It can react with the stain or the material and cause discoloration.
Common questions
Can I use hot water to remove bird droppings from concrete?
Hot water is not usually necessary, but on concrete it is safer to stay with cool water regardless, since highly porous and alkaline, so it can pull stains deep if not treated quickly.
Is it safe to scrub the stain out?
Scrubbing usually makes things worse. Blot or lift instead of rubbing, working from the outer edge inward so the stain does not spread.
What if the bird droppings stain has already dried?
A dried stain takes longer and may need repeated treatments, but the same agents still work — just re-wet the area gently first to reactivate the stain before treating it.
