Aerators are small round devices on the end of your faucet that create a mixture of air and water resulting in a smoother flower. Occasionally build up can occur in your aerator and may require gentle cleaning to ensure best performance.
Start by removing your aerator from the faucet. Your water does not need to be turned off to do so, but you may require an aerator key that can be purchased at a local home improvement store.
Once you have removed the aerator from the faucet, soak it overnight in a 50/50 water and white vinegar solution. This will help to break up any calcium deposits that may have formed. After soaking, rinse the aerator with cool water and screw back onto the faucet spout.
Frequency of aerator cleaning will depend on use and the type of water in your area.
