Many consumers, convinced they are saving energy and preserving their clothes, set all washing machine washes at 30 degrees. An apparently harmless practice which, in the long term, can turn into a real boomerang for the household appliance. Industry experts explain that always using low temperatures is not only ineffective for deep tissue hygiene, but also ends up damaging the washing machine itself.
With constant washing at 30 degrees, detergent residues, limescale, bacteria and mold accumulate in the drum, in the seals and in the internal ducts. The result? Bad smells, reduction in energy efficiency, possible breakdowns and – ironically – the need for technical interventions that make you spend much more than you thought you would save.

Periodic washing at high temperatures
A periodic cycle at 60 or 90 degrees, however, acts as a “deep cleaning” not only on the fabrics, but above all on the machine. It eliminates germs and grease, dissolves detergent residues and protects the washing machine from accumulations that compromise its functioning over time. You shouldn’t exaggerate with high temperatures, but inserting them strategically, for example once a month, is considered essential to keep the appliance efficient.
There is also a hygienic aspect that should not be underestimated: always washing at a low temperature may not completely eliminate microbes and bacteria present in garments, especially those in contact with the skin, such as towels, underwear and sheets. Modern detergent formulations have improved the effectiveness of cold washes, but are not able to completely replace the thermal action in situations where deeper sanitization is required.

How to clean the washing machine and eliminate residues
A further intervention recommended by specialists is the periodic use of citric acid (ecological alternative to descaler) diluted in water and inserted into the drum for a 60 degree cycle. This treatment helps dissolve limescale, eliminates persistent odors and restores the cleanliness of the tub, prolonging the life of the washing machine. To be repeated approximately every two or three months, especially in areas where the water is particularly hard. It’s not a miracle cure, but it makes a real difference.
Many users fear that high temperatures will wear out their clothes. True, some fabrics require delicate washing, but this does not justify the exclusive use of 30 degrees. Just read the labels and balance the cycles: delicate at 30, daily at 40, sanitizing at 60 or more when necessary.
In summary, the washing machine needs variety. Alternating low and high temperature washes not only guarantees better cleaning and hygiene, but preserves the technical efficiency of the machine. Saving a few kilowatts today by ignoring these recommendations could mean spending tomorrow on repairs or buying a new washing machine. The experts are clear: cleaning, sanitizing and using adequate temperatures is not optional, it is preventative maintenance.
