@witchfynder_finder have you tried a sponge, or a dish sponge (idunno the right word, but the ones with a coarse layer on one side)?
I generally use those when something needs really-scrubbing (but not getting scratched to hell), and I don't want any papery stuff left behind.
@pastelbat I ended up getting it off with some Goo Gone and a paper towel, actually! But I appreciate the input~ 💚
