Housekeepers in a hotel change linen, wash the floors, dust surfaces and clean the bathrooms. To ensure high levels of hygiene, the housekeeping department has to change all soaps, shampoos, lotions and towels on a daily basis. Housekeepers should also use safe antiseptics to sterilize floors and surfaces. Before a new guest checks into a room, a supervisor has to check that housekeeping has fulfilled all cleaning procedures.
