What you need to clean radiators

The first step to clean your radiators is to know what you need for proper hygiene of them. There are utensils that are very useful when cleaning radiators such as the following:

  • Vacuum cleaner
  • Duster
  • Rods
  • Sponge and rag
  • Bucket with soapy water
  • Wipes
  • Adhesive tape

These are the main materials and tools when cleaning radiators. Now let’s see how to proceed step by step to clean them.

How to clean radiators step by step


  • The first step to clean a radiatoror any electrical device, is to turn it off. We should never manipulate an electrical appliance that is on, because we could have an accident, and even risk our life and cause a fire in our house, apart from the fact that our appliance would be damaged. Remember that if an electrical appliance gets wet, this is very dangerous.
  • If you’ve had your radiator on, wait for it to cool down completely before cleaning.
  • Once the radiator is cold, and if you do not want to put everything lost, put newspapers or paper around it, so that you do not fill with water and soap while you wash your radiator. The floor and wall should be protected. Cleaning a radiator is not easy, so you will get very dirty while doing it. As the saying goes, “better safe than sorry”, so cover floors and walls near the radiator when you go to wash it.
  • Cleaning a radiator it’s got work to do, because the dust gets into every crevice and piles up in every nook and cranny, so you have to clean it up thoroughly. The work can be quite complicated, but you can help yourself with some special radiator brushes they sell for this. They are conical brushes that can reach into every corner and have the ability to trap dust. They are great for this purpose of leaving your radiators free of dust and dirt.
  • Once we are ready to start and before we get into the deep wash, let’s start removing the surface dust. To do this, all we have to do is wipe the radiator with a cloth or a duster. You can also use an air gun or dryer to blow the dust out.
  • It touches the most complex thing: cleaning the radiator inside. How do we do it? A simple trick is to tie a cloth to the end of a stick or rod that is thin and long. You can do it with adhesive tape. You will have to put it between the slits and pass it from end to end to clean it well inside. First, use a dry cloth.
  • The next step is to repeat the previous operation although, in this case, we will use a damp cloth. You don’t need to use any foreign products, but a solution of soapy water will suffice.
  • Just as you soap, it is time to rinse, since soap cannot stay in our radiator either, so insert the stick or rod again, but this time, with a cloth moistened only in water, with the idea of removing it in soap.
  • When you’ve rinsed, following the previous step, it’s our turn to dry. This is achieved by passing the stick or rod again with the rag which, on this occasion, will be a dry rag.
  • But not only the slits need cleaning, but also the inner wall of the radiator needs to be cleaned thoroughly. Again, we’ll do it with a rag-lined stick.
  • Don’t forget the corners. Here, just passing a toothbrush will be enough.


If you want to know some tricks to get rid of radiator dirtEven the most rebellious and the dust that refuses to come out, you should know that steam offers a good help to achieve this. If you have a steam machine, turn it on and apply the steam to the areas of the radiator that need cleaning. This serves to melt the dirt that has hardened over time, but also to dry out any remaining water.

We have seen how to clean radiators. Okay. But now it turns out that not all radiators are the same. In fact, you can distinguish between cast-iron radiators and metal radiators. The former have to be cleaned frequently and it is even a good idea to paint them with a paint or product that is breathable. We can dust them with a vacuum cleaner and then wipe them thoroughly with a damp cloth. If you need to, you can apply a degreaser.

Metal radiators do not need you to use a vacuum cleaner and a static cloth may be sufficient for proper sanitation, because the dust is trapped in its fabric.

How to purge radiators


The radiators come with a bleed valve. This is usually on top of the appliance, so open it and leave it open until all the water has drained out. All this operation must be done logically with the device off. You will also need to place a container to collect the water that comes out. Once finished, we still have to check the water pressure and verify that everything is correct.

Now you know how to clean radiators step by stepto get them ready for the arrival of the low temperatures.
