Difficulty: Moderately Easy * Extra Fine Powdered Pumice * Fine Silicas * Citric Acid * Oxalic Acid * soft, clean cloths 1 == Mix 4 tbsp. very fine pumice powder (yes, pumice is an abrasive) with 1/4 c. citric acid.

2 == Add 1 tbsp. finely ground silica and mix thoroughly. (Silica will help resist moisture.)

3 == Wet a soft cloth with water and rub the polish onto the metal with it.
