Can you reverse oxidized copper? If you have stubborn copper oxidation due to exposure to air and water, cover the surface of the copper with salt and begin to rub it vigorously with a soft rag. Keep rubbing until the bluish-green discoloration has disappeared.
How do you get copper back to its original color? Mix 1/2-cup distilled white vinegar (or lemon juice, which is more acidic) with 1 Tbsp. salt and enough flour to form a thin paste. Apply the paste to the copper surface and scrub away the tarnish with a cloth or scrubbing sponge. Rinse under running water and buff with a dry cloth to polish.
How do you clean heavily tarnished copper? Boil a cup of vinegar, a tablespoon of salt, and three cups of water in a large pot and add the copper item. Let it boil until the tarnish begins to come off, then remove the item, let it cool, polish, rinse, and dry.
