How to Clean or Replace a Faucet Aerator

Weak or uneven faucet flow can come from a clogged aerator rather than a larger plumbing problem. Cleaning the small screen at the spout is quick and often restores normal flow.

Tools you will probably need

  • aerator key or small pliers
  • rag

Materials

  • replacement aerator if needed
  • white vinegar for mineral buildup

Project steps

  1. Close the drain so small aerator parts cannot fall into it.
  2. Remove the aerator using the correct key or a tool protected with a rag.
  3. Rinse debris and soak mineral-coated parts in vinegar if appropriate for the finish and components.
  4. Reassemble the parts in the same order and reinstall the aerator by hand before lightly tightening.

Common mistakes

  • Losing the tiny washers or screens
  • Scratching the faucet with bare pliers
  • Assuming low pressure throughout the house is an aerator problem

When to call someone

If low flow affects multiple fixtures or the faucet body itself is leaking, the issue may be beyond the aerator and worth professional diagnosis.
