I usually use rubbing alchohol. Other popular and same choices include %3 hydrogen peroxide solution (that's the concentration it's usually commertially available at), lemon juice, and milk. A very mild soap solution would probably work. I would not recommend a bleach solution.Originally Posted by ntgerald
