I have already found out that there are no regulations about the temperature at which you should wash guest bed linen in the machine. What have your experiences been? Are there any legal regulations for hosts in your country? At what temperature do you wash the bed linen?
That's exactly what I've been doing for four years now. I always washed everything at 40°. Until today when a neighbor told me that it's compulsory in the catering industry to wash bed linen for guests at 60° for hygiene reasons. But I have to admit that this neighbor often makes up things like this. She worked in a hotel 40 years ago. Of course the world kept on turning in the meantime.
