How do you clean fools gold off of rocks?
I'm a bit more puzzled about how you get fools' gold onto rocks. Fools' gold is a type of rock... iron (II) sulfide, or iron pyrite. It's hard, brittle, and not something that could easily get smeared onto some other rock. If you somehow did manage it, it's relatively easily oxidized to the sulfate, which is soluble in water.
