Faucets can appear functional while actually suffering from reduced performance due to clogged aerators, which are small components at the spout's end that filter water flow. Over time, these aerators can accumulate mineral deposits, particularly in areas with hard water, leading to issues such as low water pressure and uneven spray patterns. According to Michigan State University Extension, regular cleaning of aerators is essential to maintain optimal water flow. The Centers for Disease Control and Prevention (CDC) recommends cleaning faucet aerators when visible buildup is present, as this can prevent contamination from germs that thrive in moist environments. A simple solution for cleaning aerators is vinegar, which effectively breaks down mineral accumulation. Homeowners are encouraged to inspect and clean aerators regularly to avoid unnecessary repairs and ensure efficient faucet operation. By following these maintenance practices, individuals can save time and money while keeping their faucets functioning properly.
