Can I clean coins with vinegar? Vinegar. A common ingredient in DIY eco-friendly cleaners, the acetic acid in white vinegar can help wear away the contamination on your coins. Soak your coins in a glass or other non-corrosive container for at least 30 minutes, up to overnight, and then wipe with a clean cloth or scrub gently with an old toothbrush.
Why does vinegar clean coins so well? When you put your dirty pennies in the vinegar and salt, the copper oxide and some of the copper dissolve in the water.

How do you clean dirty coins? Take the coins out and sprinkle some baking soda over them; then use a soft-bristled toothbrush to brush them clean. Rinse them out thoroughly with hot water; using tongs or gloves to hold them to avoid burning your fingers. Place them on a soft, cotton towel and leave to air dry.
Why can we not use vinegar alone to clean the coins? The oxygen in the air and the copper in the pennies form an oxide that coats the pennies and makes them look dirty. The acids (usually vinegar – acetic acid) break the copper oxide free from the penny. As we have seen experimentally, acid alone does not clean as well as acid and salt.
