Removing sticky stuff

[Akanbe-]

Weird topic title, i know.  I recently bought Castlevania DS from gamestop, used.  When I went to put in the cartridge, I noticed it was EXTREMELY sticky on the back.  I don't know if some dumb fuckwad put a sticker on the back of the cartridge or what, but I got a new DS lite and I baby the hell out of it.  So, i'm looking for something that could remove the stickyness.  I could take it back, but it's hard to find so I would rather try to fix this.  Also, it's a 30 minute drive one way.

To clarify, it is so sticky that if I press my thumb against the back, I can flail my arms and do jumping jacks and it does not budge.  I got some of the stickyness off, but it's still a little more sticky than i'd like.

Most oils will do it if you let them sit on the residue for a little bit, mineral oil, vegetable oil, etc..  You can also try rubbing alcohol.  I'd be really, really careful of the contacts, though.

the contacts are okay, i assume.  they look fine and don't seem to have anything visibly wrong with them.

it's just the back of the cartridge.

No, I mean don't get any mineral oil or anything on them.

There's this stuff called Goo Gone. It works pretty well, and you should probably be able to find it at a hardware store or something.
