How to Clean Kitchen Faucet Aerator

What Is a Faucet Aerator and Why Does It Get Clogged?

The aerator is the small screen attachment at the tip of your kitchen faucet. It mixes air into the water stream, reducing water usage while maintaining good pressure and preventing splashing. Over time, mineral deposits (limescale), sediment, and debris from the water supply accumulate in the aerator's mesh screen, reducing water flow and causing uneven or weak streams.

Cleaning the aerator is one of the easiest and most impactful faucet maintenance tasks — it takes about 10 minutes and can dramatically restore water pressure.

What You'll Need

• White vinegar — dissolves mineral deposits and limescale
• Microfiber cloth — to protect the faucet finish
• Old toothbrush — for scrubbing the mesh screen
• Adjustable pliers or wrench (with cloth padding to protect finish)
• Small bowl or cup
• Hibbent Replacement Faucet Aerator — if your aerator is damaged or heavily corroded

Step 1: Remove the Aerator

1. Turn off the water supply or simply turn off the faucet.
2. Wrap a microfiber cloth around the aerator to protect the finish.
3. Unscrew the aerator by hand — turn counterclockwise. Most aerators can be removed by hand.
4. If it's stuck from mineral buildup, use pliers padded with a cloth to avoid scratching.
5. Note the order of the internal components as you disassemble: typically housing, washer, mesh screen(s), and flow restrictor. Take a photo before disassembly for reference.

Step 2: Soak in White Vinegar

1. Place all aerator components in a small bowl.
2. Cover completely with undiluted white vinegar.
3. Soak for 30 minutes to 1 hour — longer for heavy mineral buildup (up to overnight).
4. The vinegar dissolves calcium and limescale deposits from the mesh and housing.

Step 3: Scrub and Rinse

1. Remove components from the vinegar.
2. Scrub the mesh screen and all parts with an old toothbrush to remove loosened deposits.
3. Hold the mesh screen up to light — all holes should be clear and open.
4. Rinse all components thoroughly under running water.

Step 4: Reassemble and Test

1. Reassemble the aerator components in the correct order (refer to your photo).
2. Screw the aerator back onto the faucet by hand — clockwise. Hand-tight is sufficient; over-tightening can crack the housing.
3. Turn on the water and check the flow — it should be even, strong, and splash-free.

When to Replace Instead of Clean

If the aerator mesh is torn, the housing is cracked, or mineral buildup is so severe that soaking doesn't clear it, replacement is the better option. The Hibbent Faucet Aerator is NSF/ANSI certified, fits 55/64" female thread (standard for most kitchen faucets), and offers dual-function spray modes — an upgrade over a basic replacement.

How Often to Clean Your Faucet Aerator

• Every 3–6 months in hard water areas
• Annually in soft water areas
• Immediately if water flow becomes weak, uneven, or starts spraying sideways

Final Thoughts

Cleaning your faucet aerator is one of the most overlooked and most rewarding kitchen maintenance tasks. A 10-minute vinegar soak can restore full water pressure and fix uneven spray patterns instantly. Make it part of your semi-annual kitchen maintenance routine.
