To maintain hygiene between deep cleans, it is recommended that surfaces be cleaned with an all-purpose cleaner or disinfectant spray. This will prevent germs from spreading and accumulating in the area. Any areas where slips or falls could be caused by cleaning supplies must be cleaned. After you are done, lock the doors to communal toilets. This will prevent anyone from getting in during cleaning. To ensure everyone can use the common toilets in a safe and clean manner, it is important to keep them clean.
