Do you wash your laundry at 40 degrees because it's "safest"? You're not alone. This number has become almost an automatic choice - like a kind of silent agreement between us and our washing machine. We turn the knob, close the door, press start. The machine hums, the water heats up, and we calmly go about our day. But while the drum is spinning, your washing machine may be literally wasting money.
It turns out that many people spend more on electricity every month simply because they automatically select higher washing temperatures. And rightly so water heating is the part of the process that uses the most energy. The higher the temperature, the higher the cost. So simple – and so overlooked.
The temperature that costs us more than we think
Laundry piles up quickly. T-shirts, jeans, sportswear, work clothes – the washing machine is turned on almost every day in many households. And if every cycle is at 40 or even 60 degrees, this is evident. Not only in the wear and tear of the fabrics, but also in the payment slip.
Research shows that it can transition from 40 to 30 degrees reduces energy consumption for about 38 percentBut if you switch even at 20 degrees, the difference can be up to 62% lower electricity bill.
Hygiene myth: is a higher temperature really necessary?
Many people insist on 40 or 60 degrees because they believe it is more hygienic. The idea that hot water kills bacteria is deeply rooted. But the modern reality is different.
Today's washing machines and detergents are designed to work effectively even at lower temperatures. Enzymes in detergents are optimized for washing at 30 degrees, where they successfully break down stains and impurities. For everyday dirty clothes, a higher temperature is simply not necessary.
T-shirts, jeans, sweaters or sportswear usually they do not require extreme heat. If they are not visibly dirty, 30 degrees is quite enough. And let's be honest - most of our clothes are not as dirty as we think. We often wash them out of habit, not out of necessity.
Lower temperature, longer life of clothes
High temperatures accelerate the wear of fibers, cause colors to fade, and can lead to shrinkage of materials. Fabrics become thinner, less elastic, and lose their shape more quickly.
If you've ever noticed that your favorite shirt isn't as vibrant in color after a few months or that your jeans have lost their original texture, the culprit may be Washing temperature too high. Washing at 30 degrees is gentler on textiles and preserves the appearance of clothes for longer.
When do higher temperatures still make sense?
Of course, this doesn't mean you should completely forget about 60 or 90 degrees. Higher temperatures have their place. Towels, bedding and children's clothes are recommended to be washed at 60 degrees for better hygiene. This involves contact with skin, moisture and possible bacteria, so a slightly higher temperature is justified.
Program at 90 degrees is usually only needed for dishcloths and cleaning cloths, where grease and microorganisms accumulate. But such cycles are much less common in the average household than washing everyday clothes.
The key is balance. Not all laundry is the same and not every stain requires a high temperature.
The next time you reach for the button and it automatically selects 40 degrees, stop for a moment. Is that really necessary? Would 30 degrees be enough? In most cases, the answer is yes. And when you open your electricity bill in a month and notice the difference, you will know that you made the right decision.
