I ordered this Pet Peed as a skeptic; this was from a new dog in our RV. I have tried a number of products on these stains. We hated looking at them on a daily basis and were starting to look at having the carpet replaced. So I found the web site and watched the video, read the comments and thought about ordering for a full day. Yes it is a bit pricey but if it works we would not have to go through the aggravation of having the carpet replaced (we are fulltime RVers). Yes it completely removed all of the stains, following the instructions and just soaking the affected area. I will buy this product again, and recommend it.
