Radiators are practical, but they are seasonal as well. Generally, they are used extensively during winter to create a warm and comfortable living environment. Before the next heating season arrives, radiators are often left idle. Therefore, it is highly necessary to properly clean and protect radiators before the next heating season to greatly preserve their condition.
Before the start of the new heating season, it is important to inspect the bleeder valves connected to radiators and the fittings on all pipes. If there are loose or detached threads, they should be re-tightened to prevent leaks after heating. If any parts are found to be worn or faulty, they should be repaired or replaced promptly. Additionally, when cleaning the surface of radiators, it is best to use a soft cloth or brush and avoid using any type of organic solvent (to prevent corrosion to the radiators). Common household detergents, such as dishwashing liquid or weakly alkaline soap water, can be used to clean the dirt on the radiator surface.
Another important note is that the material of the radiators can affect the choice of maintenance methods. Different materials require different maintenance approaches, such as steel radiators generally require full-water maintenance, while aluminum radiators do not.
Therefore, it is crucial to conduct thorough cleaning and protective measures prior to reactivating the radiator heating system.
