My cat knocked over a can of furniture stain my wiffe was using, leaving a huge spot on the living room carpet. After trying several expensive remedies with no luck, I tried a hint I read-- squirt foaming shave cream on the stain, work it into the carpet with a rag or brush, let it dry, vacuum up. You may have to repeat a few times. Just get the cheapest shave cream at the store, or try whatever you have on hand -- as long as it's NOT GEL. I was very skeptical, but it worked! At most, you've lost a dollar if it doesn't work for you. Good luck!
