William:

Typical weld paste for pickling of welds will remove the heat effected discoloration (heat tint) that you see. It is generally a blend of nitric and hydrofluoric acid in a gelled solution. After removal of the heat tint, passivation should be performed with either nitric or citric acid gel passivation. These solutions can be purchased from a number of suppliers or contact me for assistance.

Try The Magic Wand from Diversified Products. It cleans weld burns quick and easy to use.

I remember using a product while working for another fabricator. It's a charcoal gray color with, what almost looks like glitter imbedded in it. It comes in a 2" X 3" X 1/2" block and feels alot like an eraser. It won't mar the surface and you use it like a sanding block. Is anyone familiar with this? I forgot the name of the maker.
