How to dust the radiator without leaving traces of dust?
Radiators tend to accumulate dust especially if left for a long time, so a thorough cleaning is essential. To clean the radiator from dust, you can use a vacuum cleaner or hair dryer. We explain how.
Hair Dryer : A quick and easy trick to get the dust off your radiator is to use a hair dryer. For best results, first place a damp cloth behind the radiator and another on the floor. Then activate your hair dryer on a jet of cool air and direct the air towards the places where you have the most dust and dirt.
You will notice that all the dust particles settle directly on the wet clothes. Reproducing this motion throughout the winter will keep you from accumulating dust.
broom : It is a very good way to get rid of excess dust that has accumulated over time. Additionally, for a perfect clean, take a feather duster, anti-static cloth, or brush to pick up dust. They will help remove small dust residues that a vacuum cleaner is not able to neutralize.

How to properly clean the radiator?
A good dusting of the radiator before winter is essential for its proper operation and efficiency. But how do you remove any stains that make it dirty? Although cast iron radiators are difficult to come up with for cleaning because they have an “accordion” surface, you can use the same products with which you would clean an aluminum radiator or any other metal radiator.
External radiator cleaning
Take 1 liter of water and pour 1 cup of vinegar into a bucket, then add 1 cup of alcohol in the preparation and mix. Dip a sponge into the solution and run it across the surface of the cooler. Finally, rinse it with water and dry the cooler with a dry cotton cloth. Your radiators will be like new!
Another natural trick is to use baking soda, a widely used home maintenance remedy that is especially effective on yellow spots.
In a bucket, mix 3 tablespoons of baking soda and 1 liter of water. Dip a sponge into the solution and then run it across the surface of the cooler to clean it. Then, dilute 2 tablespoons of vinegar in a little water and run a sponge soaked in the vinegar over the cooler. Finally, rinse it with water and dry it with a dry cloth.
Cleaning the intercooler
It is not enough to clean the radiator on the surface to ensure proper and safe operation. A thorough cleaning of the radiator’s interior is highly recommended. With this internal cleaning, you can get rid of air bubbles that slow down the system.
First, make sure the coolant is off, then open the valve on the side. Intervention must be done very carefully, with only three-quarters of the valve open (that is, approximately half a turn, no more). If you can’t do this by hand, use pliers or a wrench. Once the water starts coming out, close the valve. Your heater is ready to go! If you are not comfortable with this type of intervention, seek professional help.
Don’t underestimate cleaning your radiator, it is important that you do it well throughout the year. These quick and easy tips will help you do just that.
