Two products ‘best to avoid’ when cleaning your radiator – risk damage

An expert has revealed two products that should be banned from your radiator cleaning routine. Otherwise, you could risk your radiators becoming vulnerable to corrosion.

When you’re doing your weekly clean, you probably don’t pay too much attention to your radiators. After toilets and floors, you might think the heating devices rank pretty low on your list of must-clean items.

However, a really dirty radiator won’t work as well at radiating heat out. Therefore, Sarah Dempsey, expert from, the UK’s leading trades matching site, explained that cleaning it should be part of your household maintenance routine.

The expert said: “If you want to keep your radiators working efficiently, it’s also worth bleeding them to remove trapped air and getting your boiler serviced annually. Leaving your radiators to accumulate dust also causes other problems, because as heat rises, so does the dirt.

“It gets pushed up into the room, irritating allergies and leaving you with black marks on your walls.”

However, it’s not only important to use the right products to clean your radiator effectively. You also need to avoid the ones that could cause damage.

The expert warned against using stiff brushes and harsh, flammable chemicals. She said: “It’s best to avoid using stiff brushes as these can scrape off your paintwork, leaving your radiators vulnerable to corrosion. 

“Harsh and flammable chemicals should also be avoided as these can damage your radiator and react with the heat when you turn your radiators back on.”

Instead of these two products, the expert recommended opting for a long, soft brush or duster. Dempsey said: “You can buy microfibre ones that are designed specifically to reach down the back and in-between the panels of your radiator.”

When it comes to getting rid of the dust and dirt the expert warned about, she recommended using something that you probably already have in your home. “A hairdryer wafted over the top also works well to blow out the loose dust and dirt,” she said.

Before you get started with the cleaning, Dempsey reminded to ensure that your central heating is turned off and your radiators are cold. 

Once your radiators are ready to be cleaned, the expert recommended getting started with the hair dryer or vacuum cleaner to remove as much dust as you can.

She continued: “Then, use a long, thin brush to reach down the back and clean out the rest. If your radiators haven’t been cleaned for a while, you might want to place a dust sheet on the floor underneath to catch the dirt as you work.”

In order for your radiators to work well, you’ll be pleased to know that you don’t need to clean them weekly. “A deep clean once or twice a year, alongside regular vacuuming and dusting will keep your radiator looking its best and working well,” the expert added.
