This is the product we use to clean the quartz crystal points and clusters mined in our commercial operation. Oxalic acid may be used multiple times with proper storage.
Directions on how to use this product will be sent with the Oxalic solution. Approximate weight of this product is 2.05 pounds per bag.
Tip: Carefully, check for a film on the crystals after you rinse after soaking. If you feel a film, rinse more. Otherwise, your crystals will have a yellow appearance.
