I purchased this a couple of months ago but was so skeptical, I only opened and tried it a few days ago. WOW! It works just like it says. It even cleaned my tile grout! I had tried everything on my grout! Tile cleaner - nope. Bleach - nope. Scouring pads -nope. Everything I could think of! Sprayed My Pet Peed on the grout, left it for about 45 minutes and wiped it off. I was STUNNED at the difference. As soon as the holidays are over, I will be doing all the grout. Tried a few places on the carpet, whoa, did it stink. But! After it dried, spots and smell gone. Decided to wait to do all of the spots until after Christmas, but definitely treating all of them. I am so impressed with how it works, I took the gate down on the stairs! (Upstairs is carpet, downstairs is tile) Now my mini dachshund can go upstairs without worrying about accidents. This stuff is the BOMB!!
