How Do I Remove White Buildup on Faucet Aerators?

Noticing white or chalky buildup around your faucet aerators? That crusty residue can reduce water pressure and affect the performance of your fixtures. In this post, we’ll explain what causes it and how you can easily clean it yourself.

What Is the White Buildup on My Faucet?

The white buildup is typically mineral deposits left behind by hard water. Over time, calcium and magnesium accumulate on your faucet’s aerator, the small screen at the tip of the faucet, causing reduced flow or uneven spray.

Why Should I Remove It?

Leaving the buildup untreated can lead to:

• Lower water pressure

• Clogged aerators

• Damage to fixtures

• Higher water bills if leaks or inefficiencies develop

How to Remove White Buildup on Faucet Aerators

Here’s a quick DIY solution:

1. Unscrew the aerator: You can usually do this by hand. If it's stuck, use pliers (wrap with a towel to avoid scratches).

2. Soak in vinegar: Place the aerator in a cup of white vinegar for 30 minutes to dissolve the minerals.

3. Scrub gently: Use an old toothbrush to remove any remaining residue.

4. Rinse and reassemble: Rinse the parts thoroughly and screw the aerator back onto the faucet.

How to Prevent Future Buildup

• Install a water softener: This helps reduce mineral content in your water.

• Clean aerators monthly: Regular maintenance prevents buildup from becoming severe.

• Use a filter: Faucet filters can reduce particles and minerals before they reach the aerator.
