Hard Water Faucet Rescue

Soaking aerators to remove calcium buildup and straighten out water flow.

An aerator clogged with grit or mineral deposits can cause uneven faucet flow. Check other fixtures first: if several are weak, cleaning one aerator may not address the supply problem.

Remove and clean

  1. Identify the aerator type in the faucet manual. A recessed aerator may need a special key; pliers are not the default tool.
  2. Close the drain or place a towel over it to catch small parts. Remove the aerator gently with the correct tool, protecting the finish.
  3. Photograph the order of its screen, washer, and insert. Rinse away loose debris.
  4. Use only the cleaner, dilution, and contact time the maker permits. If vinegar is allowed, avoid prolonged soaking of finishes or seals. Brush gently and rinse thoroughly.
  5. Reassemble in the photographed order and hand-tighten as directed. Avoid cross-threading and forcing the housing.

Check the result

Run cold and hot water and check the stream and connection for drips. If the aerator is damaged, fit the correct replacement rather than removing it permanently. Continued poor flow or debris soon returning calls for further plumbing diagnosis.

For shower jets, use the separate showerhead cleaning guide.
