How to Clean a Faucet Aerator

It's a simple repair, but cleaning an aerator can make a big difference to water flow from the faucet.

Faucet aerators mix air with the water, minimizing splashing and reducing the amount of water used (and the energy required to heat hot water) without reducing the effectiveness of the water stream. An aerator contains a screen and a water reducer/aerator washer, and these little items have a habit of collecting bits of naturally occurring mineral sediment from the water. What you’ll notice is a reduced water flow at the spout (on both hot and cold) and/or a nonsymmetrical spray coming from the spout.

Cleaning tools
Cleaning tools. Though a pick-and-hook set is best for cleaning small parts, you can improvise with tiny screwdrivers or needles. A pick-and-hook set however, will have the little turned ends that work perfectly to get washers and screens out.

 

WHAT CAN GO WRONG: Despite your best intentions, it’s easy to let the parts of an aerator fall out when you’re removing it. To prevent permanent loss of any parts, put the stopper in the sink drain before removing the aerator. If you take the aerator away from the sink, to keep from losing parts, you can disassemble it over a bowl.

 

To remove the aerator from the faucet simply turn it counterclockwise. Drop it straight down so you don’t lose any internal parts, especially the thread-sealing gasket. The threads can be either inside or outside the cap. If the cap is stuck, you will need piers to turn it (tape the jaws with electrical tape to minimize scratching). 1 Look inside the center area for sand, silt, and other waterborne debris 2. Take the center section out to check for further debris, noting the order in which things come apart 3. Check for anything stuck in the screen 4. In the flow reducer, look in the tiny side holes 5 and the center hole of the white button for debris 6. If you do not put all the pieces back together properly, there will be a leak or the water flow will not be a smooth aerated flow 7,8,9.

 

Unscrew the aerator
1. Unscrew the aerator by turning it counterclockwise. To avoid losing parts, drop it straight down from the faucet spout.

3. Pop out the center section, and you will get a screen and gasket. Keep track of the order in which the parts come out of the aerator body.

 

Check the screen
4. Check the screen for debris and flush it or remove debris with a toothpick or other pointed tool.

 

Look in the small slots
5. Look in the small slots on the sides of the aerator disk and clean them.

Cleaning Screens

Sometimes you can remove whatever is clogging an aerator by simply flushing the screen or reducer with water, turning the parts under the spray to dislodge the sediment. Soaking the parts in vinegar can also help dissolve calcium deposits. For really stubborn bits of debris, try cleaning the holes with a toothpick, large sewing needle or other small, sharp tool.
