Whether kitchen faucets, bathroom faucets, or shower faucets, regular cleaning is necessary. First, use clean water to wash the faucet. Dry with a 100% cotton cloth. If water is allowed to evaporate on the faucet surface, it can lead to a build-up of mineral deposits. Be sure to clean with a damp non-abrasive sponge and buff it dry with a clean soft cloth. To remove water spots, use warm water and a soft, damp cloth. Hard water stains may be removed using a 50/50 solution of white vinegar and water. Make sure to rinse thoroughly with water afterwards.
