I know some of you work on older PC boards that may have encoder being

Other than scrapping it, is there some ready made chemical that will
wash off the surface? Something like s Silver turnish remover?

Would a peroxide and white vinegar do something for me?

In the last couple of years I have become addicted to wiping down anything I put the soldering iron to with liquid flux. Solder Wick becomes much more effective and less heat is needed. The only time I don't is if I'm using a vacuum iron because it gums up the works.

Normally I give instructables a wide berth for their kids inane content,
but this one seems interesting - and we have plenty of trees around here
with dropped pine cones.
