Rubbing alcohol or a paste of rubbing alcohol and baking soda can be used to remove some stains. Buff with dry, soft cloth to prevent water spots. Avoid acids or acid-based cleaners. Commercial silver polish can be used to restore shine, although some brands may have a mild abrasive. A solution of a nonprecipitating water conditioner in a spray bottle can be used to prevent buildup.
Some products are available that leave a protective coating or wax that makes cleanup easier.
These cleaners are marked as safe for gold and brass plated fixtures. Thin platings may wear away with use and from abrading the surface with an abrasive cleaner. Dab dry the faucet whenever water is splashed on it. Water deposits will not form if water is not allowed to evaporate on the surface. See also window glass.
