Building cleaning workers: including janitors, maids, housekeeping cleaners, window washers, and rug shampooers: keep office buildings, hospitals, stores, apartment houses, hotels, and residences clean and in good condition. Some only do cleaning, while others have a wide range of duties.
         Janitors and cleaners perform a variety of heavy cleaning duties, such as cleaning floors, shampooing rugs, washing walls and glass, and removing rubbish. They may fix leaky faucets, empty trash cans, do painting and carpentry, replenish bathroom supplies, mow lawns, and see that heating and air-conditioning equipment works properly. On a typical day, janitors may wet- or dry-mop floors, clean bathrooms, vacuum carpets, dust furniture, make minor repairs, and exterminate insects and rodents. They also clean snow or debris from sidewalks in front of buildings and notify management of the need for major repairs. While janitors typically perform most of the duties mentioned, cleaners tend to work for companies that specialize in one type of cleaning activity, such as washing windows.
        Maids and housekeeping cleaners perform any combination of light cleaning duties to maintain private households or commercial establishments, such as hotels, restaurants, and hospitals, clean and orderly. In hotels, aside from cleaning and maintaining the premises, maids and housekeeping cleaners may deliver ironing boards, cribs, and rollaway beds to guests' rooms. In hospitals, they also may wash bed frames, brush mattresses, make beds, and disinfect and sterilize equipment and supplies with germicides and sterilizing equipment.
       Janitors, maids, and cleaners use various equipment, tools, and cleaning materials. For one job they may need a mop and bucket, for another an electric polishing machine and a special cleaning solution. Improved building materials, chemical cleaners, and power equipment have made many tasks easier and less time consuming, but cleaning workers must learn the proper use of equipment and cleaners to avoid harming floors, fixtures, and themselves.
         Cleaning supervisors coordinate, schedule, and supervise the activities of janitors and cleaners. They assign tasks and inspect building areas to see that work has been done properly, issue supplies and equipment, and inventory stocks to ensure that an adequate amount of supplies is present. They also screen and hire job applicants, train new and experienced employees, and recommend promotions, transfers, or dismissals. Supervisors may prepare reports concerning the occupancy of rooms, hours worked, and department expenses. Some also perform cleaning duties.
       Cleaners and servants in private households dust and polish furniture; sweep, mop, and wax floors; vacuum; and clean ovens, refrigerators, and bathrooms. They also may wash dishes, polish silver, and change and make beds. Some wash, fold, and iron clothes; a few wash windows. General house-workers also may take clothes and laundry to the cleaners, buy groceries, and perform many other errands.
       Working Conditions    Cleaning Maintenance
Because most office buildings are cleaned while they are empty, many cleaning workers work evening hours. Some, however, such as school and hospital custodians, work in the daytime. When there is a need for 24-hour maintenance, janitors may be assigned to shifts. Most full-time building cleaners work about 40 hours a week. Part-time cleaners usually work in the evenings and on weekends.
       Building cleaning workers in large office and residential buildings often work in teams consisting of workers who specialize in vacuuming, picking up trash, and cleaning rest rooms, among other things. Supervisors conduct inspections to ensure that the building is cleaned properly and the team is functioning efficiently.
