Laundry is easier than before. Just open the machine, load your clothes, set the programme and don’t worry about a thing. But not everyone is familiar with modern washing machines, and not everyone knows which programme is the right one.
It’s not only the washing procedures and methods that have evolved, but also the materials we wash. So it’s important to pay attention to what programme we choose and what temperature is right. As every housewife knows, too high a temperature can cause clothes to shrink. But few people realise that too low a temperature can also be a problem. If it is chosen, there is a risk not only of clothes not getting washed, but even many other complications.
Stronger detergents are no substitute for higher water temperatures and poor washing can have a negative impact on our health.
Species of health-threatening bacteria:
- Escherichia coli
- Staphylococcus aureus (golden staph)
A German research team investigating the negative effects of washing at lower temperatures has shown that 100 million intestinal bacteria are found in a washing machine that washes at 40°C or lower. Your fragrant clothes and underwear are contaminated with these bacteria, which are closely linked to many diseases. Scientists agree that only washing at temperatures above 40 degrees Celsius and using a detergent containing bleach significantly reduces the microbes that threaten us.
If you want to at least partially eliminate the germs found in your washing machine, keep your washing machine door clean, including the door seal and detergent drawer.

Try to use multiple programs on your washing machine
Not all laundry needs to be washed at 40°C or lower. For more durable materials, try washing at 60 °C. Towels, tea towels and many bed linens can easily withstand a wash programme labeled tumble, which is a temperature in excess of 90 °C.
The higher temperature programme should be used if there is a sick person or allergy sufferer at home. This is the only way to minimise dust mites and bacteria.
Last but not least, not every laundry needs to be treated with a mild liquid product. It turns out that until most people used strong detergents, bacteria didn’t have as much of a chance to take up residence in our laundry. That has changed today.
Wash wisely
Separate your underwear carefully from other items. Always wash children’s clothes separately, and the same goes for towels and washcloths.
By following these few guidelines for proper laundering, you can easily minimize the risk of laundry germs ending up in your mouth.
