TIL a trick for cleaning quartz crystals from a dig in Arkansas
Had a bunch of quartz from the Ouachitas with that rusty iron oxide stain. Tried muriatic acid but it was too harsh. Switched to oxalic acid crystals, about a tablespoon per gallon of warm water. Soaked them for 48 hours and the stain was gone without any etching. Anyone know a good way to get rid of clay stains after that?

Clay stains are the worst, feel your pain.

Clay stains turn my nice finds into lumpy potatoes, it's so frustrating. I once left some in soapy water for a week and they came out looking like weird, shiny soap bars. Would a soft toothbrush help after a good soak, or is that just asking for scratches?
