A Dirty Hotel Secret
Zero waste is something eco-conscious hotels are striving for, but there are a lot of rumors flying around about their practices. Considering the room you are showering in and sleeping in has already been used by up to thousands of other people, hotels are kind of unhygienic by definition.
You don’t know how well those rooms are cleaned or if those clean-looking glasses are really clean. The least we would expect though is the linens to be boil-washed with a strong detergent, not one that’s been homemade from leftover bars of soap.
