Hi Susan,
Thank you for your review of the Delta Faucet HydroRain® 4-Setting Two-In-One Shower Head MODEL#: 75698CZ. Please accept our sincere apology for the inconvenience you are experiencing. We are always happy to assist. Quality is very important to us and our products undergo rigorous testing to ensure high-quality performance.
We recommend to always blot dry any water from the faucet surface. Allowing water to evaporate on the surface can lead to a build-up of mineral deposits. Cleaning with a damp non-abrasive sponge and buffing it dry with a clean soft cloth should help keep your product 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 thoroughly with water afterward.
Our products do have a Limited Lifetime Warranty that covers parts (other than electronic parts and batteries) and finishes of Delta® faucets purchased from authorized Delta sellers to the original consumer purchaser to be free from defects in material and workmanship for as long as the original consumer purchaser owns the home in which the faucet was first installed. I have included a link below for the warranty information.
