I want to know if it is really safe to be using washers and dryers that other people use. There is no telling what they had on their clothes and what can get into the washers and onto other people’s clothes.Very safe.
The detergent in the washing water and the water temperature destroy whatever bacterial or viral pollution there might be on the clothes of the person before you.
And the temperature used for drying, as well as the drying out of the clothes, does the same thing once again.
No virus or bacteria does well with detergent, high heat and low humidity.
Just don’t leave your clean clothes lying in the common room, don’t hang them up , and you’re safe.
