The kitchen sprayer is a handy device that can be used for spraying items in the sink. Over time, mineral deposits from the water supply build up inside the sprayer nozzle, causing the mechanism in the sprayer to stick. The sprayer head is easily removed from its port next to the faucet and cleaned with simple household tools.
Turn off the water supply to the faucet. The water supply valve is below the sink in the cabinet. Open the faucet to drain the water remaining in the pipes.
Remove the sprayer head from the hose. Most sprayer heads can be easily twisted off by hand. If yours proves more difficult, use an adjustable wrench to spin the head coupling off of the hose. Place some masking tape on the teeth of the adjustable wrench so the wrench does not scratch or dig into the sprayer head housing or coupling.
Place the sprayer head into a bowl. Pour enough white vinegar into a bowl to cover the sprayer head. Scrub the inside of the head and around the handle of the nozzle gently. Be careful not to damage any washers or screws as you scrub. Soak the sprayer in the vinegar for several hours.
Remove the sprayer from the vinegar. Rinse thoroughly. Dry with paper towels or a clean rag. Replace the sprayer head back onto the hose.
Turn on the water supply. Test the sprayer.
