The aerator is a small, mesh screen at the end of your faucet that helps regulate the flow of water. Over time, it can become clogged with debris and mineral deposits, causing a decrease in water pressure. To clean the aerator, unscrew it from the faucet and soak it in a mixture of equal parts water and vinegar for about 30 minutes. Rinse it off and screw it back onto the faucet.Clean the aerator
