How to Clean Inside a Radiator

Dirty Radiator Internals

Mrs Hinch has spurred on a nation of cleaning lovers, but aside from floral-scented disinfectants and well-plumped grey cushions, there’s a myriad of information, tips and tricks to help clean your home that can be gained from a good search online. One such job is how to clean inside a radiator, in order to best extract dust, dirt and accumulated mess.

Radiators are often left out of daily or weekly household cleaning routines, simply because they so easily fade into the backdrop of our room’s aesthetics. However, cleaning dust from radiators around the home reaps benefits for those who take the time to do it, even just periodically – in allowing for them to work more efficiently in both terms of performance and cost. Clean radiators allow for better airflow through rooms and can work for less time and at less power to heat a home, as well as lasting longer at the optimum performance before they one day need replacing.

Whilst it’s easy to understand how to clean out an open appliance such as a towel radiator, taking on a more traditional column radiator can be a little trickier.

If you’re looking for details on how to clean the dust inside a radiator to better enhance its performance, notice the warmth more, to save on your energy bills or to improve your home’s interior air quality, you’ve come to the right place: Great Rads has all the info you need!

Useful Tools for Cleaning Dust from Radiators

You don’t need any specialist equipment to clean dust from a radiator, nor do you need to remove it from the wall – so don’t panic! There are radiator cleaning brushes available to get between the slats and clean out those hard-to-reach spots, but it’s worth giving it a go with items you already have at home first, as plenty of people find they don’t need to make any extra purchases.

To clean the dust from the inside of your radiator, first ensure that it’s turned off. This avoids any burns to you or your cleaning equipment, but also means that the convection current isn’t running – so no further dust can be drawn into the radiator as you work. Then, hoover all around your radiator (above and below), and if you have an attachment that allows for targeted vacuuming, attempt to suck out what you can from inside the fins and slats.

To create your own radiator brush, simply wrap a piece of wood or long thin object in a microfibre cloth or duster around it and secure it. Use this to reach inside of the radiator and clean the dust out from within – but only if you’re confident that the cleaning component is well constructed enough not to break within.

Use warm soapy water along all parts of the radiator that you can reach to wipe it down to damp, then dry with a (clean) microfibre cloth to mop up any residual dust left over. Make sure all parts are thoroughly dried after, as any moisture left could result in rust.

Further Tips for Cleaning Your Radiators

Of course, every home and radiator are different, and cleaning styles and individual accessibility will vary. There are a lot of tips for cleaning radiators available online, so try out several and see what works best for you.

Many people use hairdryers to blow out any dust from hidden nooks and crannies in their radiators, but take caution when doing this. You don’t want to just distribute the dust elsewhere around your home (particularly if anyone in the household has allergies or asthma), but it can be a great way to clear out areas you’re not able to otherwise access.

Cleaning the inside of a radiator is advised at least annually, but if kept on top of as part of a regular cleaning routine, there’s no need for a full ‘deep clean’. Once the initial radiator cleaning is complete, just add in a quick dust or hoover for a few minutes each week or month and avoid the build-up of unnecessary dust.

Never remove a radiator panel to clean inside of it as you may damage the inner workings of the appliance. All areas requiring cleaning are accessible from the outside, so there’s no need to dismantle it. If you have cleaned your radiator and still feel it isn’t working properly, contact a professional for specialist service.

One of the first things you’ll find when you look up information on how to clean a radiator online is targeted adverts for cleaning products and brushes, but many people are able to effectively clean dust from the inside of their radiators without having to spend any extra money.
