My $7 secret for perfectly dust-free radiators – this quick task also slashes my winter energy bills, too

It's a must-do at the start of fall

As the temperature outside starts its gradual decline, my heating is looking increasingly tempting.

However, after a long summer untouched, my radiators are coated in dust. It's not just an aesthetic problem; it risks higher energy bills and musty smells.

The quickest way to get dust off your radiators before turning the heating on

So far as cleaning tips go, this one is pretty self-explanatory.

Use the clean, dry brush to poke down into all the gaps in your radiator to push out the dust that has settled inside and against the wall.

Putting a dust sheet, from Walmart, or an old towel underneath the radiator can help to collect any clumps that are dislodged, but I find a quick run around with the best cordless vacuum after dusting to be more than sufficient.

It's quick, cheap, and easy, not to mention far less damaging than the awful internet trend of pouring a bucket of water through your wall-mounted radiators. That is a one-way ticket to mold and rust.

Although dusting radiators might not sound like an important fall cleaning task, it is one of the best ways to make heating more efficient, with the result being increased comfort and savings on energy bills.

Nick Barber, co-founder at Utilities Now, explains, 'Dust not only impacts airflow, it also decreases heat transfer efficiency.

'When you have dust accumulation on radiators, baseboard heaters, or furnace heat exchangers, the system cannot move heat as efficiently, so it must operate longer to achieve the same temperature.

'Dusting radiators and vents and having an annual HVAC tune-up keeps the system running efficiently.'

As someone who already struggles to keep a poorly insulated home warm, it is a must-do fall home maintenance task every year.
