SPAREX Pickle for cleaning metal
10 oz 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. 10 oz.
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 fasted warmed.
