How do you clean your Genesis cases?

[josekortez]

Often, I find complete Genesis games at yard sales & thrifts, but the cases are cruddy. When I first starting picking them up this way, I would wipe the cases with a paper towel doused in water/alcohol, but even this doesn't do the trick. Now, I dunk them in a bucket or soap and water and let them dry. (Of course I remove the insert and manuals first...)

What other methods are there out there?

For label residue, some inks, and general gunk like that you can use the miracle liquid, Goo Gone. Works great, has a nice orange smell, and can sometimes be found at Dollar Tree.
