If your faucet has low water pressure, uneven flow, or white residue around the spout, the issue is likely a clogged faucet aerator—not your plumbing.

Hard water and mineral buildup are common in U.S. homes, but the fix is simple. In this guide, you’ll learn how to clean a faucet aerator, why it’s important, and how often to do it.

What Is a Faucet Aerator?

A faucet aerator is the small mesh screen located at the tip of your faucet. Its job is to:

• Regulate water flow

• Reduce splashing

• Improve water efficiency

• Filter out debris and sediment

However, minerals like calcium and magnesium—common in hard water—can clog the aerator, leading to poor performance.

Signs Your Faucet Aerator Needs Cleaning

If you notice any of the following, it’s time to act:

• Low water pressure from the faucet

• Uneven or sideways water spray

• White or chalky mineral deposits

• Black debris or sand-like particles in water

These are classic signs of limescale buildup and sediment blockage.

How to Clean a Faucet Aerator (Step-by-Step)

What You’ll Need:

• Adjustable wrench or pliers

• White vinegar

• Small bowl

• Old toothbrush or soft brush

• Paper towel or cloth

Step 1: Remove the Aerator

Gently unscrew the aerator from the faucet tip. Use a cloth between the tool and the faucet to avoid scratches.

Step 2: Disassemble the Aerator

Take note of the order of the internal parts (screens, washers). Laying them out helps with reassembly.

Step 3: Soak in Vinegar

Place all parts in a bowl of white vinegar for 30–60 minutes. This dissolves calcium and mineral deposits naturally.

Step 4: Scrub and Rinse

Use a toothbrush to remove loosened debris. Rinse thoroughly with warm water.

Step 5: Reassemble and Reinstall

Put the parts back together in the correct order and screw the aerator back onto the faucet.

How Often Should You Clean a Faucet Aerator?

For most U.S. homes:

• Every 3–6 months in normal conditions

• Every 1–3 months, if you have hard water

Regular cleaning prevents long-term mineral damage and keeps your faucet performing like new.

Benefits of Regular Faucet Aerator Cleaning

Cleaning your faucet aerator regularly can:

• Restore strong water pressure

• Improve water quality and clarity

• Extend faucet lifespan

• Reduce plumbing issues

• Save water and energy

It’s one of the easiest home maintenance tasks with immediate results.

Final Thoughts

A clogged faucet aerator is a small problem that can cause big frustration—but it’s also one of the easiest fixes. With just vinegar and a few minutes, you can restore water flow, reduce mineral buildup, and keep your faucet working efficiently.

If you’re dealing with persistent hard water issues, regular faucet aerator cleaning should be part of your home maintenance routine.
