2. Inspect and Clean: Rinse the aerator under running water. If mineral deposits are present, soak the aerator in a solution of equal parts white vinegar and water for 30 minutes to an hour. Use a small brush (like an old toothbrush) to gently scrub away any remaining deposits.
3. Reinstall: Reinstall the clean aerator by following the installation steps outlined in Section 3.
