You know, with that annoying guy and commercial that runs every 5 minutes? I was curious so I went on usenet and searched, and a lot of people have good things to say about it. Most of the posts said it does a great job on organic stains (like dirt) and in the laundry getting rid of stains. I was thinking it might be the ticket to get rid of the discoloration around the dead pedal in my car, nothing get's that out... With this stuff as a pre-treater and then my little green clean machine, the carpet should look good. I'm skeptical, but doing a usenet search ususally let's you know what's bunk pretty quick...
