The aerator at the end of your water faucet (shown below) adds air into the water to reduce splashing and limit the flow of excess water. Aerators catch some of the silt, minerals, and other debris that can flow through your tap water, which can cause a build-up and affect your home’s water quality over time. 

Most aerators simply unscrew from the faucet, but you may need to use a pair of pliers or a wrench. Once your aerator is removed, separate its parts and remove any debris. Soak the parts in white vinegar and scrub with a brush. Rinse and reassemble the cleaned aerator, then screw it back onto the faucet.
