We must first of all have neutral dish soap, a microfiber cloth, rags and, if we have it, a steam cleaner.
We frequently dust the radiators of cast iron radiators in order to remove dirt deposits that can reduce the release of heat.
A particularly effective solution to eliminate excess dust is to place a slightly damp cloth behind the cast iron radiator and point cold air towards it; in a few seconds the dust will be captured by the cloth. To eliminate any residual dust, you can use a duvet or a long-handled brush, so as to be able to reach the most hidden corners more easily and clean easily in the middle of the various sectors of the cast iron radiator. p>
To remove the most stubborn stains, and avoid yellowing of the cast iron, we can use a mixture of warm water and a few drops of neutral dish detergent and a degreaser for more stubborn dirt.
We pour the solution into a spray dispenser and spray on the affected areas after placing a sheet of newspaper under the radiator to collect the dirt that will drip to the floor.
Steam cleaning will also sanitize the structure: we pass the steam cleaner directly on the radiator to dissolve any limescale residues, then dry with a soft cloth before starting with the final cleaning. During this phase, we carry out the purging of the radiators to expel further waste and limescale, which would tend to reduce the efficiency of the radiator. To complete the work, clean the radiator again with the steam cleaner and dry with a cloth.
