Every October, the first time the heating clicks on, my living room used to smell of burnt dust. That smell comes from the fluff, pet hair and cobwebs trapped between the fins of the radiator, where no duster ever reaches. A neighbor showed me her trick years ago: an open bag taped under the radiator to catch everything, then a hair dryer and a long brush to push the dust down into it. It takes about fifteen minutes per radiator, the floor stays clean, and the warm air coming off the radiator afterwards feels and smells much fresher. Do it now, while the radiators are still cold.
What you need
- 1 per radiator large plastic bin bag or an old pillowcase, cut open along one side
- 1 roll painter's tape or masking tape
- 1 hair dryer with a cool setting
- 1 long, thin radiator brush (or a ruler wrapped in a microfiber cloth)
- about 1 quart (1 liter) bucket of warm water with a few drops of dish soap
- 2 microfiber cloths
- 1 vacuum cleaner with a crevice nozzle
How to do it
- Turn the radiator off and let it cool completely. Never work on a hot radiator, and for electric heaters, unplug them first.
- Lay the opened bag flat on the floor under the radiator, slide one long edge up against the wall and tape it there, then tape the front edge to the floor or skirting so the bag forms a wide tray under the whole radiator.
- Vacuum the top grille and the visible fins with the crevice nozzle to remove the loose layer first. This stops a cloud of dust going into the room in the next step.
- Set the hair dryer to cool or low and point it down through the top of the radiator, working slowly from one end to the other. The dust that has been sitting inside for years drops straight down onto the bag.
- Push the long brush down between the panels and fins, wiggle it gently and pull it back up. Repeat along the whole length. Blow again with the hair dryer to send the freed dust down.
- Carefully fold the bag inward from the edges so nothing spills, and take it outside to the trash. You will be surprised how much grey fluff is in there.
- Wipe the outside of the radiator, the wall behind it and the floor with a cloth dipped in the soapy water and well wrung out, then dry with the second cloth.
Good to know
- A wet towel under the radiator works too, but the taped bag catches more and goes straight in the trash.
- If you have allergies, wear a simple dust mask and open a window while you blow the dust out.
- Do not use a hair dryer on its hottest setting, and never spray liquid inside an electric heater.
- Doing this once before winter and once in midwinter keeps that burnt-dust smell away for good.
Ten minutes of work per radiator and the first warm evening of the season smells like a clean house again. Tell me how much dust came out of yours!
