Ah, I thought I was the only one! I usually use one of those small towels, but when I think it's getting a bit dirty and I can't do the washing yet or something, I use paper towels. Except they're not normal paper towels - they're really soft but durable, and quite big... dunno where my aunt gets them, but she gives me some in bulk!! That way I know it's clean every time I use one!
