Note: Do not wash your crystals in the sink since clay is likely to plug your drain.
For larger crystals that are hard to clean, a pressure washer may be considered. More difficult residues to remove are gold/brown iron oxide and grey/black manganese oxide. Most rock hounds use an oxalic acid bath to remove this residue. This acid is mild, but can be very dangerous to the skin and lungs if the fumes are inhaled. Oxalic acid is not a product carried by Fire Mountain Gems and Beads, but more product availability, use and safety information may be found online.
