how can i restore a tarnish/staining on a piece of steel(gray or dark gray color desired)?
Try thisIn a shallow pan put a sheet of aluminum foil, about 8 by 8Pour in some hot water with a lot of salt disolved in itNow add about a cup of vinagarTouch the aluminum under water with the tarnished metalThe salt/vinegar solution will allow the tarnish to move from the metal to the aluminumWorks great on silver too.
