Why do laundromats advise against washing clothes at 40 degrees?

4. Wash bedding with cold water

Dust mites thrive in blankets, bed sheets, and pillowcases. Not only that, but they are susceptible to yellow stains caused by dead cells and sweat released by the body.

Washing with cold water will save some power, but it will not adequately remove yellow stains or kill bacteria.

It is preferable to wash them with hot water every two weeks, but be cautious not to use too hot water to avoid deforming the material.

5. Cleaning the washing machine

There are small gaps and holes between the washing drum and the exterior shell of the washing machine that allows water to enter and depart. During the washing process, dirt will adhere to the inside of the washing machine or the corners of the drain pipe via these microscopic gaps and holes, producing bacteria.
