Understanding the Function of an Aerator
How Aerators Work
Aerators are small yet vital components that play an important role in the functionality of your faucet. They are mesh screens designed to fit into the tip of the faucet spout, where they carefully regulate and enhance water flow. By mixing air with the water stream, aerators reduce splashing, conserve water, and create a smooth, steady flow. This process improves efficiency and ensures a more pleasant experience when using the faucet.
Why They Get Clogged
Despite their usefulness, aerators are prone to clogging over time. Mineral deposits from hard water gradually accumulate on the mesh, restricting water flow. Additionally, sediment and debris carried through the pipes can become trapped in the aerator. Unaddressed clogged aerators can lead to poor water pressure and erratic flow patterns. To avoid these problems, it is crucial to clean your aerator regularly. Routine maintenance will ensure optimal performance, prolong the life of your faucet, and help maintain consistent water efficiency.

Removing the Moen Faucet Aerator
Step 1: Protecting the Faucet
Begin by wrapping a soft cloth around the base of the faucet to shield it from scratches or other potential damage during the removal process. This step ensures that your faucet remains in pristine condition while you work.
Step 2: Loosening the Aerator
Use a pair of pliers or a wrench to turn the aerator counterclockwise carefully. Apply only gentle pressure to prevent damaging the aerator or the faucet. If the aerator is particularly tight and difficult to turn, try using a rubber jar opener or wrap a piece of cloth over the aerator for an improved grip. These methods can provide the extra leverage needed without causing harm to the components.
Step 3: Removing the Aerator
Once the aerator is loosened, pull it straight off the faucet spout. Be cautious during this step to avoid misplacing small components like washers or screens inside the aerator. These parts are vital to the aerator’s function and may require cleaning or replacement before reassembly.

How to Clean Moen Faucet Aerator Soaking the Aerator
Step 1: Preparing the Soak Solution
Fill a small container or bowl with enough white vinegar to fully submerge the aerator. White vinegar is an excellent natural cleaning agent that effectively breaks down mineral deposits and debris. Mix the vinegar with water in a 1:1 ratio if a gentler solution is preferred. Ensure the container is large enough to accommodate the aerator while keeping it entirely submerged for an efficient cleaning process.
Step 2: Soaking the Aerator
Carefully submerge the aerator in the vinegar solution, fully covering all parts. Allow the aerator to soak for at least 30 minutes to an hour to loosen debris and mineral buildup. You may extend the soaking time up to 12 hours for aerators with stubborn or heavy deposits. During this time, the acidity of the vinegar will dissolve the particles, making them easier to remove.
Step 3: Scrubbing
After the soak, gently remove the aerator from the solution and inspect it for remaining debris. Use a soft brush, such as an old toothbrush, to scrub away any loosened deposits. Pay special attention to the mesh screen and any small or hard-to-reach areas. Avoid using abrasive tools that could damage the parts. This step ensures the aerator functions optimally after reassembly.
Step 4: Rinsing
Thoroughly rinse the aerator under warm water to remove any traces of vinegar or loose debris. Ensure all parts are clean and residue-free before drying or progressing to the next step. Proper rinsing leaves the aerator ready for reinstallation and helps maintain the faucet’s performance.

Cleaning Stubborn Build-Up
If mineral deposits remain after the previous cleaning steps, additional methods can help restore your aerator.
Using Baking Soda for Stubborn Mineral Deposits
Baking soda is a versatile and gentle cleaning agent, perfect for tackling tougher build-up. To use, create a paste by mixing baking soda with a small amount of water until a thick consistency is achieved. Apply this paste to the aerator, ensuring it covers areas with stubborn deposits. Allow it to sit for 10-15 minutes, giving the paste time to break down the minerals. Then, use a soft brush or cloth to scrub the aerator thoroughly. When finished, rinse under warm water to wash away the residue and assess the results.
Using Commercial Descaler
A commercial descaler specifically designed for faucets may be necessary for particularly challenging mineral deposits. These solutions are formulated to dissolve tough limescale and calcium deposits without damaging the aerator. Follow the manufacturer’s instructions closely to ensure safe and effective use. Apply the descaler as directed, allowing it to work for the recommended duration before thoroughly rinsing the aerator with water. Use this method sparingly to maintain the longevity of your fixture.
By using these techniques, you can effectively handle stubborn mineral buildup, leaving your faucet aerator clean and working as intended.
