Always blot dry any water from the high arc kitchen faucet surface. Allowing water to evaporate on the surface can lead to the build-up of mineral deposits. Cleaning luxury kitchen faucets with a damp non-abrasive sponge and buffing it dry with a clean soft cloth should help keep your single kitchen faucet looking beautiful. 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 certain that you rinse the surface thoroughly with water afterward.
