Compound 302

Application Instructions:
  • Stir or shake well for uniform consistency.
  • Apply Compound 302 onto the weldment, weld-burn, or discolored area by acid brush or plastic spatula.
  • Leave it on for approximately 30 seconds to two minutes; then rub with a stainless steel brush or piece of cloth in the direction of the grain on the surface.
  • Wipe with a wet sponge or use water rinse. Some grades of stainless steel may tend to flash rust. To avoid this condition, neutralize the area being treated with an alkaline solution made with Sodium Carbonate or a solution of water and dish washing liquid.
  • Repeat application if required.
Area of Application:

Compound 302 is an innovative chemical formulation of paste-like consistency containing deoxidizing and surface active agents in addition to fine compounding materials. It effectively removes heat-discoloration, weld-burn, (including blueing) and rust from all grades of stainless steel. Compound 302 also works great to clean and deoxidize copper, brass and bronze.
