Cleaning Celluloid Pieces
 

Hello Everyone.

Long time lurker -- seeking some advice from the Board's pinback collectors.

I generally don't clean new acquisitions, but recently have picked up a couple of buttons that could use some cleaning.

What do you guys use (if anything) to clean celluloids?

What should I steer away from?

Thank you for your help in advance!

Could a Mod please move this over to the memorabilia side? :o

Thank you!
