How to clean your radiator exterior

Radiators sometimes fly under the radar of places to clean in a room, but after a while they gather as much dust and grime as anywhere. Plus, they require some special attention as the space behind the radiator and its fins can be a little awkward to clean and dust. If you’re not sure how to clean dust from inside radiators and between its fins, read on for our top tips on how to clean behind radiators and get dust and grim out of all their awkward crannies.

Keep your radiator spotless and germ-free by giving it a regular clean with an antibacterial cleaning spray.

Why cleaning radiators exterior is important

While dirt on your radiator might be unsightly, that’s not the only reason to get rid of it. Dust between the fins of a normal radiator essentially acts as an insulator on its surface trapping the heat in, making it much less efficient when it comes to warming up your room. So if you want to save some pennies on your heating bill it’s worth knowing how to clean radiator exteriors, especially getting into every area to ensure they’re completely dust free.

Cleaning radiator exteriors: where to start

To get going on your radiator cleaning project, here are a few first steps:

  1. Turn the heating off – it’s much safer to clean them when they aren’t hot to touch.
  2. Use a duster and a vacuum to remove superficial dirt and dust from the easier to reach areas.
  3. Give the exterior a once-over with a germ-killing cleaning spray. Be sure to wait for it to dry before turning the heating back on.

How to clean behind radiators

Cleaning behind radiators can be tricky depending on how close they are to your wall. There are a few good techniques to know when it comes to this, and you can apply the same methods to work out how to clean dust from inside radiators. Try one of these methods and see how you get on:

  1. Use a specialist radiator cleaning brush. These are perfect for cleaning behind radiators, as they’re designed to get right into narrow spaces to remove dust and dirt.
  2. Small vacuum-cleaner attachments that fit down behind the radiator.
  3. Make your own DIY radiator cleaner. Simply take a long piece of wood and wrap a cloth around one end (use tape to keep it in place). Push it down the back of the radiator to dislodge any nasties and get a nice clean finish.

If you’re also wondering how to clean radiator fins while you’re cleaning the radiator’s exterior, these techniques should be handy for these too.

Those are our top tips when it comes to cleaning every part of your radiator. Make a habit of doing it every few months to stop dirt building up, and you can relax in the knowledge that none of that precious radiator heat is going to waste.
