hey guys...it's been a looong time coming, but I really need to clean all my nes and snes cartridges.

Question: I don't have windex, will Mr. Clean work equally as well?

Question: Is it true I can use toothpaste on the contacts? Will my ultrabright Advanced Whitening Toothpaste work? How does this compare to using Brasso?

thanks...I'll be going to the store in an hour...so I eagerly await whatever help you guys can give me.
