This is a fantastic non-acid pickle for removing oxidation and firescale, which means no toxic fumes or corrosion on the work bench. Jewelers can use steel tweezers in the pickle pot. No more copper tweezers, no contaminating! And it will not hurt spring rings. Powder form makes one gallon when water is added. Non-hazardous to ship. 1 Gallon.
This product is good for 1 year after mixing it with water.
