You’ve heard of using baking soda to clean the grime off of your pots and pans, but did you know that you can also use it to clean your dirty coins?

If you don’t mind your coins getting a few microscopic scratches, you can try using baking soda and water to clean them. Just soak coins in a bowl of warm water and baking soda. Let it sit for 1-2 hours, then brush them.

Here are the exact steps to clean your old coins with baking soda.

Let’s get started!

What You’ll Need:

3. Pour warm water over the coins once more, scrubbing with your toothbrush, to remove any leftover baking soda. You’ll likely have to repeat this step a few times before the cleaning is effective.

4. Dry off all of your clean coins with a paper towel.

Warning: I repeat. Cleaning with baking soda can leave micro-scratches that are visible under a microscope. So if you collect coins or plan on selling them in the future, then don’t use baking soda because doing so can ruin their value. This is for coins you plan to display only.

Can I Use White Vinegar with Baking Soda to Clean Coins?

Yes. You can soak your coins in vinegar for 10-15 minutes before doing the steps above. Vinegar is an acid and can help in removing rust and tarnish off coins.
