Any suggestions on how to clean these without causing damage?? I'm
guessing some sort of solvent bath plus a toothbrush would do the trick,
but I don't want to dissolve anything important.

IPA is reccommended by Keysight. I buy "eBay graded" IPA. Supposed to be 99.9%, but any more than 80% would be a bonus!
I would not immerse anything, even in IPA.
I had some 3.5 mm connectors with foam on them from an HP cal kit. I could not clean it off. I tried IPA in an ultrasonic cleaner, but that would not touch it either. Then I tried acetone. That melted bits of the connectors. I everntually stuck on eBay as for spares or repair, and they were bought by yikunhk - the HP rebirthing centre.
