I have an old coffee/tea stain on the arm of my white leather lounge, and although Napisan has worked well on the rest of the leather this stain won't budge.
I suggest this for all stains. Try LA's Totally Awesome. There are different dilution amounts listed on the side of the bottle. It works the best on everything I have ever tried it on, and only costs about $1. You can only find it at your local $1 stores.
