Hello Hammer, Thank you for your inquiry! Here is the cleaning here instructions that we recommend for our Delta faucets: Always blot dry any water from faucet surface. Allowing water to evaporate on the surface can lead to 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. If additional cleaning is required, all of our finishes may be cleaned with the following household cleaners: Formula 409® Antibacterial All Purpose Cleaner, Fantastik® All Purpose Cleaner, or Windex® Original Glass Cleaner, when used according to the manufacturers' instructions for use. Avoid using the following which can damage your finish: Avoid industrial cleaners and abrasive cleaners, such as those used for toilet bowls, green Scotch-Brite heavy duty scrub sponges, Scrubbing Bubbles Bathroom Cleaner and Lysol Basin Tub, Soft Scrub, and Tile Cleaner. Avoid products that state on the label that they remove tarnish and rust, and those containing hydrofluoric, hydrochloric and/or phosphoric acids and caustic agents. Avoid harsh abrasives or polishes. Avoid bleach-based cleaners Best regards, Tanya

Thank you for your question, Allan! Delta kitchen faucet sprayers use a diverter, which is a moving valve that shifts the water flow back and forth between the faucet spout and the sprayer. When you activate the sprayer handle, the diverter shuts down the flow to the spout. When you release the sprayer handle, the diverter opens again and lets the water flow into the spout. Please know that it is normal to have a thin stream of water coming from the spout whenever the sprayer is being used. If you are getting more than a pencil-thin stream of water from the spout then we would ask that you contact us for further assistance at 1-800-345-3358 Monday-Friday: 8a.m.-8p.m. EST and Saturday: 9a.m.-6p.m. EST or via email at customerservice@deltafaucet.com.
