I need some help! I purchased an advertising piece made of celluloid. The problem is that it has the residue from an old price sticker on it. Does anyone have a cleaning method for celluloid? I wary of using heat or any of the new cleaners on the market.

Thanks in advance.

BTW, I'm looking for hub mold chips hot-stamped with the initials GB and FJH as shown below. Please email me if you have any for sale or trade. Thanks.
