Effectively removes heat-tint, weld-burn and discoloration and rust from all grades of stainless steel. It is a unique chemical formulation of paste-like consistency, with mineral acids, deoxidizers and penetrants. The active ingredients dissolve the hard-to-remove blue oxidation color and weld-burn. It clings to vertical, horizontal and intricate surfaces and can be applied by a cloth. Compound 302 can also be used as a general acid cleaner for copper, brass and bronze.

Always use hand and eye protection.
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.
