Myths and truths about washing

1. "Bacteria disappear in 60 degrees"

FALSE

- Bacteria are everywhere. Harmful bacteria live and spread as long as there is food (dirt and moisture). So it is better to really wash away the dirt and then using the temperature for which the detergent is adapted. Water itself also contains bacteria that can grow if you do not dry the laundry quickly and efficiently. Tumble drying has been found to have a much better effect on killing any bacteria than high washing temperatures.

2. "The sheets start to smell good again if you wash it in 60 degrees or more"

FALSE

- A sheet that smells bad is not easy to get back in the original condition. If a garment has begun to smell that way, it will not help to wash warmer. Try a rinse in dilute vinegar and citric acid, then dry. However, Lyocell is naturally antibacterial which counteracts bad odor and bacteria growth.

3 "Everything that can be washed in dryers should also do so"

FALSE

- Obviously, it becomes an unnecessary wear that shortens the life of beddings. You should never tumble dry anything that is not properly centrifuged because it becomes a very unnecessary energy load. Drying bedding through hanging also makes them less wrinkled.

4. "You should change detergents from time to time because they have different effects"

TRUE

- Some detergents are good at low washing temperatures and others require high temperatures because they contain some form of bleach that you may want to have in their whitewash (but only works on cotton). It is also good to change the detergent sometimes to get another environment in the washing machine that can also have a lot of bacteria in it. Do not forget to open the door to dry between the washers.

5. "You should use fabric softener"

FALSE

- Fabric softener is not good for the environment, the largest part ends up in the drain. The part that remains on the textile material gives a slightly more hydrophobic effect (and binds water), which means that the bedding breathes worse.

6. "The more detergent the cleaner the laundry"

FALSE

- About 80% of Sweden has soft water, which means that less detergent is required. Using too much detergent causes it to foam a lot and then wash it worse as there is no water for the dirt to travel and it will also be difficult to rinse afterward. Rinsing to get rid of dirt and chemical residues are at least as important for a good washing process.

Tip!

Instead of washing on too high temperatures and tearing on both the environment and your clothes/beddings, there is an old trick which says that once a month, you should run an empty washing machine at the highest temperature (90-95 degrees) with 3 deciliters of vinegar instead of detergent. This descales your washing machine and keeps it clean and fresh, which in turn prevents bacterial spread.

Another tip is to switch your cotton sheets to Lyocell. Apart from being way softer, Lyocell has 10 times lower bacteria growth than cotton thanks to its breathability and moisture absorption ability.
