...from things that are sensitive and can't be scrubbed too hard and then buffed out?

This is for a bass amp that I bought off some yokels on CL. Cool piece, but they must've thought they were recreating the I Am The Walrus video set because there's florescent shit all over it. I could easily scrub the print off the control panel if I'm not too careful. I'm trying some cooking oil. It seems to be working okay, but I'm wondering if anyone has a secret weapon.
