Compound 302 post-weld stainless steel cleaner 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.
