Electric towel rails are amongst the dirtiest parts of the bathroom! Are you one of the 6 out of 10 who clean them less than once a week? Here’s how to clean them...


Do you find yourself picking and choosing which areas to wipe down when it comes to cleaning your bathroom? If you’re someone who just focuses on thoroughly scrubbing your toilet, sink, and shower, it might be time to consider adding your radiator or towel rail into the mix too. That’s right, we’ve discovered that these areas are often neglected in people’s deep clean routines and that they’re, notably, some of the dirtiest areas of the bathroom!

Towel rails are amongst some of the dirtiest parts of your bathroom – here’s how to clean them


According to our survey*, 69% of Brits say they feel more conscious of the cleanliness of their home and personal hygiene since the Covid-19 pandemic, so we wanted to find out how often Brits say they clean their bathroom and which parts they clean the most.

Unsurprisingly, the toilet seat is the most cleaned item in the bathroom, followed by the toilet basin and sink with an average of 30% of homeowners cleaning these every day – followed by an average of 51% opting to clean these items between 4 days to once a week. 

Despite 24% of people saying they clean their radiator once a week and 29% of people saying they clean their towel rails once a week as well,  we discovered that 6 in 10 bathroom heaters we assessed, including towel rails, were actually really dirty

We used surface hygiene swabs on 5 bathroom items to detect spoilage or pathogenic bacteria to indicate biological contamination, revealing whether the surfaces were clean or not. Of all the bathroom items swabbed, the dirtiest was the heater (radiator or towel rail), followed by the toilet seat and sink plughole. The cleanest items were the sink taps and the showerhead.

As the bathroom is notoriously a moist environment, one that is used regularly by households and their visitors who splash water and leave damp towels to rest on their towel rails, over time, towel rails become a hotspot for dirt and bacteria. Therefore, it is important to clean them as often as possible to avoid contamination; we recommend cleaning your bathroom radiator or towel rail at least once a week.

Our top tips to deep cleaning your towel heater or radiator

  1. Turn it off! 


Safety always comes first, to avoid scolding yourself or creating an electrical risk, make sure your heater is turned off and be sure to thoroughly dry the appliance at the end of the cleaning process.

  1. Use a cloth or soft brush to remove dirt. 


Over time, dirt and dust will build up on your heater. Make sure it’s brushed away before getting the wipe out! 

  1. Apply cleaning solution and wipe clean.


Most marks will come out with a bit of elbow grease. If you have watermarks, use a glass cleaner to get rid of them. Use warm PH-neutral soapy water or a good non-abrasive cleaning spray to do this so it doesn’t damage the surface.  

  1. Use a toothbrush to reach tricky areas. 


To remove grime from the hard-to-reach nooks and crannies, use an old soft-bristled toothbrush and get scrubbing.

  1. Dry and polish with a microfibre cloth.

Use a soft cloth to dry the appliance, making sure any streaks are wiped away. If your radiator or towel rail has a chrome or metallic finish, take extra care to polish it working in circular motions using a tea towel. 

We recommend you repeat this process at least once a week.
