Formula for Copper & Brass Cleaner


  • 1/2 cup all-purpose flour
  • 1/2 cup salt
  • 1/2 cup powdered detergent
  • 3/4 cup white vinegar
  • 1/4 cup lemon juice
  • 1/2 cup very warm water

Mix flour, salt and detergent in a bowl. Add remaining ingredients and stir. Transfer mixture to a quart jar, close tightly and label for future use.

To use, shake jar, then pour some of the cleaner on the brass/copper surface and rub gently with a dishcloth. For tough spots, scrub with an old toothbrush or a plastic scouring pad. Rinse, dry and polish with a soft cloth.


3/4 gallon Water
1/2 pound Whiting
1 pound Tripoli
1/2 pound Silica
3 ounces Oxalic Acid

PROCESS: Mix well in a 10 quart pail. Cleans all metals, prevents rust. Put in coloring, if desired (use water soluble acid proof color).

NOTE: The oxalic acid renders this poisonous. If desired non-poisonous, substitute Citric Acid for the oxalic. Use finest powdered tripoli and powdered silica possible to avoid scratching of surface being polished.
