Tres part question here, although all of it is in the same vein. First, DVD style cases like Xbox, PS2, and GameCube games, as well as *surprising* DVDs. What's the best way to get smudges and stuff off them? Some of mine have collected an inordinate amount, especially games my friends play like Halo and Shattered Soldier. Know any good ways to remove these? I'm not I want to try the washcloth method until I hear it actually works, since water alone seems to just make things worse.

Also, glossy manuals and boxes. Same thing. Any good ways to get smudges off those? I imagine something with a light enough amount of moisture to not get through the shininess may work.

Thanks a bunch for anyone who can chime in.
