Thoughts on cleaning this?

[FrankWakefield]

What I would do is bust it out of that non-original-altering plastic, and then, at a calm moment in my life I'd gently use the pantyhose method. Then I'd put the card in a sleeve and a top loader and be done with it.

Since the PSA slab seems to matter to you, I think you should leave well enough alone. It doesn't sound like you're gonna sell the card so it really doesn't matter what kind of slab it's in.

It's a nice looking card.

My old man once told me that cleaning things is a feckless waste of time and energy because every time you clean something, it makes something else dirty.

And what is the best way to remove gum stain residue from pantyhose ?

My guess would be an old sportscard.

Suggest you try it on a raw common first from same set (or era). In fact, I might try it but I can't fit into my wife's nylons anymore since I've not gone to the gym in 10 months.... lol

I can understand the itch to try to "fix" it, but if you aren't trying to flip the card - it's going to be a huge hassle to pop it, (try to) clean it, and then resub it. That's assuming you are successful. As many times as I've tried to do something like that, I usually end up making the situation worse. Good luck.

I had a nearly identical situation. Bought a PSA 7 ST '68 Mantle, and a year or two later cracked it out and easily wiped away the gunk (yes, with panty hose) and resubmitted it. It came back nicely as a straight 7.
