I was looking for something unscented that really removed cat spray around our house and this was recommended to me by a pet store.  It's been over 5 years and I will never use anything else! Just douse any surface with cast spray and stains and if you cover it entirely, the smell is gone almost immediately!  It's great to keep cats from going back to spots they've sprayed to spray again because they can't find it.  I've used it on clothes, carpet, pillows, couches, tile, hardwood, whatever!  Everything I tried before, including enzymes, left a mix of fragrance and cat pee lingering.  Not with eco-88!
