A couple of years ago I spilt quite a large quantity of sage green paint on my brown carpet, I managed to clean most of it up however you can still see some of the stain when the light hits it. It's an oldish carpet and we were planning on replacing it however we are now looking to move and don't want to spend unnecessary money replacing it if it can be cleaned. Can anyone recommend any products/tips for cleaning an old paint stain from a carpet please?
