Im at my wits ends. No matter what I try I can not remove the urine stain on my commercial tile left over from my dogs occasional accidents.confused: any help? After mopping it looks gone to only appear again after floor is dry...

Have you tried any of the oxy-clean products?
Start with a medium concentration and step it up if necessary.
Frankly, I've had great result cleaning up after my cat.
Good luck!

What kind of tile is it? An enzyme based cleaner may be safer for some tile.
