SPAREX Pickle for cleaning metal
2 1/2 lb bag
Sparex is an easy to use, longer lasting, safe replacement for dangerous sulfuric acid in effective cleaning and pickling metals. Use Sparex No. 2 for removing surface oxidation, scale and pickling gold, silver and copper based alloys. Non-flammable and non-explosive. 2 1/2 lb
I put a couple of tablespoons of Sparex in a small designated crock pot for metal cleaning. It lasts for several months. It can be used cold or warm, but it works faster warmed.
