UK Outlets Share Hairdryer Tip to Clean Radiators for Faster Warm-Up

Dust build-up can trap heat inside radiators, raising energy costs.

Overview

  • Specialists at Trads Cast Iron Radiators say a hairdryer set to cool or low can blow dust from inside and behind units, including column and cast-iron models.
  • The recommended process includes turning off heating, wiping surfaces, vacuuming underneath, placing a towel, using a long duster for grooves, blowing dust downward, washing nearby surfaces, and fully drying before switching back on.
  • Readers are cautioned not to use a hot setting because it can send dust into the air and around the room, and to keep a vacuum ready to capture the dislodged debris.
  • The coverage asserts that cleaner radiators warm rooms more quickly because dust can act like insulation that reduces heat transfer and may push up bills.
  • Liverpool Echo, the Daily Mirror and others republished the guidance on Oct. 13–14 via the Express, and the advice has not been independently tested.
