Try a slightly dampened sponge. A few years ago, I bought a sponge block in the cat dept at the local pet store just to remove the hair off my dark eggplant chenille furniture. It worked well but as usual, it eventually turned up missing. Now I just take a regular sponge, wet it and then wring the heck out of it to get any excess water out of it. It works just as well as the one that I paid more money for!!
