chicken poop stains on concrete floor

[MaryFrances]

My pretty porch floor has some stains from chicken poop that was not washed off on time.

Some stains are white, some are dark. The concrete floor has lots of little pebbles in it; it's really pretty and I would love to get it clean!

I use Oxy-Boost to clean concrete. It's like OxiClean, but has more of the active ingredient and none of the artificial fragrance. You mix it with really hot water. It's really good for cleaning organic stains. Something like that may help.

Did you have success cleaning your patio? I have one that my geese have frequented and need to find something to get stains off too!!! I'd love to know what you've tried and how it worked.

Thanks,
Claire
