It is recommended that you first check the toilets of cafes/restaurants for hygiene before deciding to drink or eat there. The cleanliness of the visible areas is of course important, but we cannot properly analyze the cleanliness of the non-visible areas by eye. Despite regular cleaning, surfaces can be infested with microbes. For example, if you wash your hands while and after entering the toilet, your hands will come again in contact with bacteria by touching the door handle. By using Prosteriel you can reduce germ transmission to the minimum.
