What do you guys use to clean the plastic casing of your games? I got a bunch of games over the last few weeks and they are sitting in the "quarantine" box. I cant put them up until they are cleaned. these are particularly dirty with gold marker, pin and ink on some labels, sticker residue and just plain dirty. I also have some PS2 games with dirty clear plastic coverings. What is the best to use on these different surfaces, the SNES hard plastic, dirty paper labels and the more sensitive clear PS2 clear plastic?
