Hello DOLORES,
Thank you for sharing your experience with us. We recommend wiping down your faucet after use to avoid spots, build-up, and cleaning with a 50/50 solution of water and white distilled vinegar to help protect the finish and remove water deposits or calcium. If needed, a mild antibacterial soap can also be used. We do not recommend using harsh cleaners or chemicals on your fixture because it will ruin the product's finish. If the cleaning solution doesn't help, we'd like to help you with your product. Pfister stands behind its products and warranties. Please contact our Support Team at 1-800-732-8238; we'll gladly assist.
Thank you,
Pfister
