I found a product called Winning Colours stain remover that is just incredible. I put a little on a paint stain on the carpet that had been there since we moved in about 2 years ago and it almost instantly started to get rid of it! I couldn't believe it. It is an eco-friendly product also. Anyways, just thought I would pass it along. It works just as good on a lot of other stains amd it is called Winning Colours stain remover.
