Cleaning the inside of the radiator is a little more complex.
The first step is to remove the dust accumulations between the radiator fins. To do this, we suggest using a vacuum cleaner with a thin nozzle that can fit between the radiator slots. Insert the nozzle from one end, and try to close the other end to create a “suction” effect.
If this method is not applicable, you can try to insert a fairly long tool between the cracks, to which you need to tie a microfibre cloth.
In a bucket, mix warm water with white vinegar, baking soda and a little soap. Dampen a cloth and try to pass it between the cracks of the radiator where possible. Finally, use a dry cloth to remove residue and dirt.
