Every day, more and more specialists in clothing care and energy efficiency are warning about the disadvantages of washing at 40°C, a common practice. Although this temperature seems to be the ideal solution for certain fabrics, recent studies show that it is possible to obtain the same results, and even better ones, at lower temperatures.
Advances in washing machine technology and the development of more efficient detergents mean that clothes can be washed completely clean at temperatures of 30°C or even 20°C, without having to resort to washing programs that consume more energy and can damage fabrics.
The risks of washing at 40°C
One of the main problems of drying at 40°C is the accelerated wear of the clothes. At this temperature, the fibers of the fabrics suffer more stress, which can cause wrinkles that are difficult to remove and even irreversible damage in delicate fabrics, such as those made with synthetic or natural materials like wool and silk.
In addition, color loss is more frequent, especially in dark or brightly colored fish, which can fade over time and lose their original appearance. In contrast, rinsing at lower temperatures helps to preserve color intensity and keeps fish in better condition for longer.
Another key aspect is energy consumption. Scalding water to 40°C involves a considerable expenditure of electricity, which not only affects the wallet, but also has a significant environmental impact. According to various studies, reducing the temperature of the washing from 40°C to 30°C can decrease energy consumption by more than 30%, which represents a notable saving on the electricity bill and a lower carbon footprint.
As if that were not enough, washing at 40°C does not always guarantee the total elimination of germs and bacteria. Because specific products such as textile disinfectants are used, some bacteria can survive at this temperature. In cases where disinfection is crucial, such as baby clothes, towels or bedding of sick people, it is preferable to resort to higher temperatures (60°C or more) or to use antibacterial additives.
Washing at 30°C or less: an effective alternative
Reducing the washing temperature to 30°C, or even 20°C, can offer surprising results. Thanks to advances in washing machine technology and the development of more efficient detergents, cleaning dishes is still effective without the need to resort to higher temperatures.
To maximize results at low temperatures, experts recommend:
- Treat visible stains with specific products before washing, especially if they are grease, wine or coffee stains, which can be more difficult to remove.
- Opt for longer cycles, as when washing with cold water, the detergent needs more time to act and break down the dirt effectively.
- Use detergents designed for low temperatures, which contain active enzymes capable of eliminating dirt and bacteria without the need for hot water.
- Do not overload the washing machine, as an excess of clothes hinders the circulation of water and detergent, reducing the effectiveness of the wash.
Low-temperature washing programs have been designed to adapt to different types of fabric. From cotton to technical and synthetic fabrics, there are now options that guarantee optimal cleaning without compromising the durability of the fabric.
Benefits of adopting lower temperatures
Washing clothes at temperatures below 40°C not only extends the lifespan of the fibers and preserves their colors better, but also significantly reduces energy consumption. This translates into a lower environmental impact and long-term economic savings.
In addition, modern washing machines are designed to maximize efficiency even in cold washing programs. Many of them include pre-wash or spin options, which help eliminate damage without the need to resort to high temperatures.
Another important benefit is the reduction of plastic microfibers in the water. It has been shown that washing synthetic clothes at high temperatures contributes to the release of microplastics into the oceans, which affects marine ecosystems. Opting for lower temperatures helps to minimize this environmental problem.
Finally, choosing to wash at a lower temperature also favors the conservation of special fabrics, such as sportswear with technical fabrics, delicate lingerie or woolen garments, which can shrink or deform in the heat.
Conclusion: lower temperature, more benefits
So why continue drying at 40°C when you can achieve the same results with less wear and tear on your clothes and lower electricity bills? Opting for lower temperatures is a smart decision for your wardrobe and for the planet.
If you still have doubts, try reducing the temperature of your next few washes and see the results. You will probably be surprised by the effectiveness of washing in cold and, at the same time, contribute to a more sustainable and efficient lifestyle.
