Wax stains on the back of cards

I have seen that nylons/dress socks can get wax stains off of the glossy front of cards, but what would work for a stain on the back of the card? I have a Rocky Bleier RC that got an 8ST from PSA and an 80/6 from SGC that I'd like to have a better grade on.
Any ideas? Thanks in advance.
