this stuff is miraculous! my poor little kit was recently sick, which made him unable to control where he went to the bathroom. my apartment was a disaster with sick kitty urine stains and stenches. the clean up effort was for naught because every commercial product i used was ineffective at killing the odor. (i had ONLY tried other all natural products, incidentally. so i don't know how well the chemically toxic ones work.)
i bought this product at the local pet shop as kinda my last hope. it not only works very well at odor elimination, it leaves a fresh scent. and of course, eliminates the stain.
saturate the stain on the carpet (or wherever). wait a minute or two. give it a good rub with a cloth (or paper towel, if you're into throwing away trees unnecessarily), and then just let it dry.
(oh yeah. check first on a hidden spot of the surface you're cleaning to make sure it's not color fast.)
the product has natural cultures in it that consume the bio-matter you're cleaning (e.g., urine, poo, hurl, etc.). once the bio-matter is gone, the stain & odor are gone. it's wonderful!
it's similar to what yogurt does in your digestive system. gets rid of the nasties.
so yeah. i totally recommend this.
