So I've found a lot of information about how to clean SNES cartridges themselves, but not really a lot about cleaning the labels.
What fluids are safe to use when cleaning labels? How do you normally clean them? Any techniques?
Specifically, I guess, I've got this used A Link to the Past cart that has a very small bluish stain on it that I'd like to try and get off. There are also some scratches on the surface of the label that I'm wondering if there's any way to sort of 'buff them out' -- although I realize that this is probably impossible.
Edit: How is windex for this job? Would I damage the label in any way by doing this? I'm really having a hard time thinking of ways to clean a label that won't damage it.
