Here is find out how to clear radiators earlier than turning them on


When winter arrives, one of the nicest ways to protect yourself from the cold is to turn on the heaters.

How many times have you put clothes on to warm them up or warm your hands, which cool immediately?

Having them in the house is essential, but they must be cleaned before lighting them, otherwise they may generate bad odors and malfunction.

Here are some tips for cleaning radiators before turning them on in winter!

Hair dryer tip

The first thing to do is to remove the dust from all the radiators in your house.

During the summer season, a very large amount of dust accumulates which could reduce the performance of your heating system.

The best thing to do is to use the hair dryer!

Yes, the hair dryer will allow dust to escape quickly and easily.

Just put a damp cloth behind the radiator and another on the floor under the radiator, then turn on the hair dryer, set it to medium speed with cold air and run it over all areas of the radiator.

The damp cloth on the floor will absorb all the dirt!

Dust bin method

You can also use a mixture of water and Marseille soap.

NB For this method, it is important to put towels under the radiator to absorb the water and to place a basin on top that covers the entire width of the radiator, so that when the water runs out, it does not wet not the ground.

Fill a container (or a carafe) with hot water and dissolve a tablespoon of liquid Marseille soap or shavings in it.

Carefully pour it into all the holes in the radiator and let the water run. It is recommended to let it run completely and to check from time to time whether it is necessary to change the cloth or basin.

After that you can dry it by placing a microfiber cloth on the hanger or on a stick or old ladle and inserting it into the spaces. Remember to rinse it if necessary.

Let a whole day pass and make sure all the water has dried up.

Important: if there are parquet or delicate floors and coverings, it is better to proceed only with the trick of the hair dryer.

Interior cleaning

Once you have completed the above step, all you have to do is start cleaning.

Here is how you can clean the inside of the radiator.

When you open the radiator valve, a lot of dirty water comes out. Place a basin under the valve and unscrew it very carefully.

Use a tool wrench you have or the special wrench that is usually found in the radiator packaging.

It is important to only let out black water, which is the dirtiest, and then close the valve.

If you have more modern radiators, ask an expert to help you with this procedure, as they will need to regulate the air pressure.

Exterior cleaning

All that remains is to clean the exterior! This step must in particular be carried out at least several times a year, even when the radiator is not in use.

You can use different ingredients to deeply degrease cast iron and aluminum radiators, let’s see them together!

Cast iron radiators

Cast iron radiators are more delicate than aluminum radiators, so care should be taken.

The best ingredient to use is Marseille soap because it will degrease, perfume and remove stains, combined with the cleaning action of baking soda.

Put 3 tablespoons of soap in a bowl and add the baking soda until you get a thick mixture.

Put the resulting paste on a sponge and lightly rub the entire radiator, including the back.

Then rinse with a microfiber cloth and let dry completely.

Aluminum radiators

Aluminum radiators are very easy to clean.

For effective cleaning, you will need vinegar and lemon. These two ingredients have a strong degreasing effect and do not leave traces on the aluminum.

Just fill a bucket with hot water and add half a glass of vinegar and the juice of a lemon.

Use a cloth to wash, first with plenty of water, then dry.

If there are any stains, use a sponge and, with the non-abrasive side, scrub until the stain is completely removed.

You can also put the solution in a spray bottle by filling it with hot water and adding two tablespoons of vinegar and three tablespoons of filtered lemon juice to it.

NB You have to be extra careful if you have marble floors.


Follow the directions carefully to avoid staining the floor. If the radiators show particular anomalies, it is best to seek the advice of an expert before cleaning them.
