How do you clean your discs?

[UpFromTheAshes]

I've bought a few used discs from a shop near my house that have the former owners' name/phone written on them in marker. Is there an easy way to get this cleaned off without damaging the plastic?

I assume nail polish remover would work since I use that to remove the factory logos and text when I customize a disc.

put a little acetone on a rag and wipe em off.
You can sand em a little bit, but after a certain point its illegal. Its mainly to get some of the scuff marks out of it, and to get some of the sharp edges from being dangerous. Anything beyond that is against the rulebook.
But like stated, just use a chemical to get em off. Never tried nail polish remover, but I have used acetone for when i was dying my discs and know for a fact that it works.
