Because your Classic Mules copper drinkware is 100% copper with no coating (on the inside), they will oxidize/tarnish… but not to worry, we’ve got you covered! The best practice to slow the tarnishing is to wash after use (with minimal chemicals) and then dry immediately.

**Never Put In Your Dishwasher**

If you start to see some oxidizing/tarnishing, here’s some sure shot ways to get that copper shine back:

Shining Method 1

Use a copper polish (we prefer Bar Keepers Friend cleanser and Polisher)

Shining Method 2 (what we usually do)

What you need!

  • 3 tablespoons of Salt
  • 1/2 a cup of Vinegar


  1. Dissolve 3 tablespoons of salt into 1/2 a cup of white vinegar
  2. Once salt is fully dissolved, dip a cloth or sponge into the solution and start gently rubbing away the tarnish.
  3. After all the tarnish is gone, rinse with water and then dry immediately with a clean cloth.
  4. A variation to the above is to fill a spray bottle with the solution and spray the copper, let it sit for a while, then rub clean.

Shining Method 3

What you need!

  • 1 1/2 tablespoons of Salt
  • 1/2 a cup of Lemon Juice


  1. Dissolve 1 1/2 tablespoons of salt into 1/2 cup of Lemon Juice
  2. Proceed cleaning your copper with the same steps as ‘Method 2’
  3. There are other cleaning methods out there if you search online… However, we’ve found the above 3 to be the best and safest methods.
