Cleaning Instructions:

Your Copper mugs will change color over time. Natural oxidation creates different spots of brown, black, and green. This is proof the item is 100 percent copper. It is safe and normal. A simple clean can restore the shine if you wish to do so. The Statue of Liberty is a perfect example of copper changing color.

Methods for cleaning:

Method 1: Cut a lemon in half and sprinkle salt on it. Gently squeeze the lemon to mix the juice and salt, then rub the lemon over the copper mug. This method works well for large areas and can quickly clean the mug. Rinse with warm water, dry, and polish.

Method 2: Mix one tablespoon of salt with two tablespoons of vinegar and apply the solution to the copper. Scrub with a soft cloth or sponge until the stains fade.

Method 3: Fill the mug with warm water and add some lemon juice or vinegar. Let the mixture sit for 30 minutes, then rinse.

Method 4: Mix baking soda with water, lemon juice, or vinegar to create a paste or mixture. Rub the mixture onto the mug, then rinse and buff.

Avoid using coarse scrubs or dish soap, as they can damage the copper.
