OMG! This is THE best stain and odor remover I have ever used. I have tried EVERYTHING. I have a cat and have had trouble removing stains from cat vomit and other fluids from white high dollar carpets. Not even professionals could remove. Seriously. I was just about to give up and replace my favorite snow white Cantoni Italian shag rug after professional cleaner said no way the stains will come out. I bought this stuff only because I got a new puppy and everyone said I had to remove the scent on the tile if she peed on it. I noticed it could be used for carpet stains, so I tried it on the rug as a last resort. Voila! Holy cow..it worked! No extra effort. I just sprayed it on and left it like the directions said and ALL of the stains from my cat throwing up came right up. I tried it on my other carpets where a foster cat had destroyed the carpet. WOW! It worked. Got rid of the smell. Got rid of the stains. I really can't believe it. Those carpets are white also. I don't think I would try it on a coloured carpet without testing it since it worked so well on my white carpets. As far as stone, It works with the puppy accidents but you have to clean up the mess first then spray it and let it dry or let it sit for ten minutes.
She has not returned to the scene to do her business. All I can say is I need to buy this is bulk.
