I had gotten this for my daughter over a year ago, and she said how good it was. I have hard floors, but light yellow rugs on either side of our bed. Our youngest pup threw up on one a couple of weeks ago, leaving a dark brown stain. I ordered My Pet Peed, and it arrived on Tuesday. I sprayed some on the stain and left. No rubbing or anything. The stain literally disappeared. I can't even find where it was!! That sold me!
