Have the sheets in the hotel room been disinfected after each guest checked out?

According to the regulations, the guest room sheets of hotels and guesthouses should be replaced at least after the guests leave the hotel, and the replaced sheets must be cleaned and disinfected.

I believe all hotels can be cleaned, but disinfection is hard to say. Perhaps most hotels will abide by the regulations, but individual hotels are hard to say. After all, it will increase the cost of the hotel, and it is hard to say whether the guests will be disinfected.

There are some problems upstairs. There are many ways of disinfection, even wet disinfection (such as disinfectant) has many kinds, and it is not necessary to leave ugly stains.
