To protect a copper finish, it is recommended that a coating of wax is applied to the surface. Most wax products have natural and added UV filters that help guard against color and finish degradation. Wax should be applied as often as necessary, depending upon usage.
It is recommended that you use a cleaner or polish that is designed specifically for copper products. You may use a gentle soap, such as dish washing liquid and warm water. We recommend the use of a soft sponge or microfiber washcloth. Do not use any abrasive cleaning pads or materials. Rinse with warm water and dry with a clean, soft cloth.
Acidic cleaners, such as lemon juice and vinegar, will strip the antique finish from the copper. Mixtures containing acidic chemicals should be avoided to preserve the finish. Epsom, or bath salts, should not be used in copper tubs, as they will tarnish and corrode the copper's appearance.
