I was sceptical at first since everything else I've looked up and tried has not worked but then I saw this product which has a lot of good reviews so I bought 2 one gal bottles. I read everything on the bottle and saw I did have to scrub ��� freaking amazing � I got it in the other day and saw a big difference with just one application and with two the stains are all gone and no smell anymore � Thank you My Pet Peed
