How to Clean a Radiator Valve?

Published in Home Maintenance 1 min read

Cleaning a steam radiator air vent valve primarily involves removing mineral deposits and rust to ensure proper function. Here's a step-by-step guide:

  1. Remove the Air Vent: Use an open-end wrench to carefully detach the air vent from the radiator.

  2. Soak in Vinegar: Submerge the removed air vent in hot vinegar for about 30 minutes. This helps dissolve rust and free up any stuck moving parts.

  3. Rinse Thoroughly: After soaking, rinse the air vent with cold water for approximately one minute to remove any remaining vinegar and loosened debris.

  4. Test the Air Vent: Blow through the vent to check for airflow and proper function. If it's still blocked, repeat the soaking and rinsing process. If it remains blocked, the valve may need replacement.
