How to Clean the Outside of a Radiator
Keep your radiators clean and well-maintained. (Hemera Technologies/ Images)

Maintaining a clean radiator can help keep heating bills down by allowing the radiator to work at its highest efficiency. Dirt can actually prevent heat from being released into the room, so a radiator will have to work harder to warm the room to the desired temperature. A clean radiator also looks better than a dirty one and can be painted to fit into the decor of the room. For the best results, check and thoroughly clean your radiators annually and do lighter cleaning on a regular basis.

  1. 1

    Shut off the radiator and allow it to cool completely. The best time to do a thorough cleaning is when the weather is warm and the radiator is off anyway.

  2. 2

    Remove any built-up dust on the surface and in the crevices with a duster.

  3. 3

    Vacuum the radiator with a brush attachment, getting into crevices as well as underneath and around the radiator.

  4. 4

    Lay dust sheets or old towels on the floor beneath the radiator to protect it from drips.

  5. 5

    Spray the radiator generously with an all-purpose cleaner. Moisten a sponge and rub the cleaning solution over the surface. Allow the cleaner to sit on the surface of the radiator for a few minutes.

  6. 6

    Scrub the radiator with a wet sponge to remove all of the surface dirt. Wring the sponge out in a bucket of water and re-wet it as necessary.

  7. 7

    Rinse the radiator with a sponge that's been wet with clean water.

  8. 8

    Dry the radiator with a towel. Once completely dry, the radiator can be turned on.

  9. 9

    Dust the radiator at least once a week.

Tips and warnings

  • Avoid using abrasive cleaners, which can damage the radiator's surface.
