Sparex
Sparex’s unique blend of ingredients make it the bench jeweler’s favorite pickle. Blended with extenders and wetting agents, Sparex is longer lasting and more effective than stand dry acid compounds. It minimizes hazards, over-pickling and pitting, producing a smooth, clean, bright surface.
Sparex No.2 is formulated for pickling gold, silver, brass, and other copper based alloys.
Sparex No.1’s added chemistry help it neutralize iron oxides when pickling iron and steel. Historically, it has been used mainly by repair and restoration shops in the gun and auto industries. However, due to the shift into alternative metals, Sparex No.1 is becoming increasingly popular within the jewelry and hobby industries.
10 ounces of Sparex mixes with water to make one quart of solution. The 2.5 pound size makes a gallon. Sparex No.1 is available in 2.5 pound cans. Sparex No.2 is available in 10 ounce and 2.5 pound bags. Both are available in 45 pound pails.
