Took the heads off my '71 Ludwig Acrolite and there's these black marks around a good bit of the drum where the head would rest.
Some of it came off just with water and a cloth, but not much. I've since tried dish soap and Goo-Gone with no success. Any help? Thanks!

I’ve seen many anodized shells with that rub-wear from hoop collars. I usually just clean off what I can and live with the rest, you can’t see it when heads are on anyway.

I'll have to consult my sister's husband as she's still got some on her knees.

Maybe try vinegar, rubbing alcohol, windex, lighter fluid, or a magic erase sponge. If you have a steady hand, lightly scrape with a razor blade. Maybe a metal polishing cloth.

Have that on my 70's Acro...heads and hoop cover it fine. Honestly I am doubtful as far as it's complete removal....Just sayin'

Yes, it is that dreaded rub-wear from hoop collars! Every single anodized aluminium shell I’ve seen has it!
It does not come off completely. You can try to remove it to some degree with automotive rubbing compound!

As previously mentioned, it is caused by tight fitting heads, with the hoop rubbing against the shell. Not much you can really do about it, but the heads cover it up anyway!
