Hey y'all. Got a set that I'm restoring and it still has the original calfskin heads. Unfortunately, they've got dirt, stick marks, and a bunch of other stuff on them. I want to keep the heads on, because they're cool (and look great despite the dirt/stick marks for the age of the drum.
I was wondering if anyone here has experience cleaning 60+ year old calfskin heads and could lend some advice.
Any help, as always, is greatly appreciated!
