How to clean poo stains off concrete?!

[TwistedSteel]

Yeah the pressure washer is best, it will make you wonder how you ever managed without it.

Have you tried TSP? It gets grease stains off concrete. Trisodium phosphate.

Thank you for all the good info guys! We're going to start with the power washer this weekend and go from there!

White vinegar, soak, scrub. Not fun but it works

If all else fails, you could do an acid wash. Pool supply and concrete finishers have it. It will remove the top layer of the cement, might make it rougher if you let it go too long. I had a plaster pool and used it, works on the green scum algae stains.

Nice suggestion! Thank you!!

The vinegar suggestion would be a mild form of this remedy, might give it a go first!

Ooh! How could I forget the household magic that is TSC!!!???

This stuff is great, pretty mild compared to other surfactants, low odor and breaks up mildew and mold off our siding and shudders with little effort- I bet it would annihilate poo stains! We use it for lots of outdoor cleaning (and indoor, for that matter)!

White vinegar is pretty high in acids and chicken poo is pretty alkaline in comparison so I'd think it would break it up nicely! We use it to clean pet dishes and coops and it works great and kills several mold types and some bacteria!

Bleach is a strong, excellent cleaner. We use it on our cement basement floor with our cat's hairballs and other things.
