Is Copper Moscow Mule Mug dishwasher safe?
Not dishwasher safe✓ Verified
No — the dishwasher tarnishes, discolors, and dulls copper mugs.
Why
Dishwasher detergent and heat react with the copper surface, causing oxidation, dark spots, and a dull finish. Lacquered mugs can also have their protective coating stripped, and the interior tin/nickel lining can be damaged.
How to wash it
Hand wash gently with mild soap and warm water, dry immediately. To restore shine, use a copper polish or a paste of lemon juice and salt, then rinse and dry.
