Sea salt, flour, and vinegar—that’s it. These all-natural ingredients that are commonly used in baking are all it takes to get your Mule mugs sparkly and clean. You can also clean copper with lemons and salt —but hey, sometimes we forget to buy lemons, so the flour + salt + vinegar combo is a great recipe to have in your collection.

What You Need


  • 1/4 Cup fine sea salt
  • 1/4 Cup all purpose flour
  • White vinegar
  • Mixing bowl
  • Soft rag

The more vinegar you add, the thinner the paste, so pour slowly!

3. Rub the paste onto the copper using a cloth (a sock works too!) until it shines.
