cleaner

Cleaner is a term with several related meanings. It can refer to a person whose job is to remove dirt and grime from spaces, such as a house cleaner, janitor, custodian, or commercial cleaning staff. It can also denote a device or chemical used to remove dirt, including cleaning products, solvents, or equipment.

In occupational use, cleaners perform routines to maintain hygiene, safety, and appearance. Household cleaners may be responsible for cleaning kitchens, bathrooms, floors, and surfaces. In healthcare, cleaners follow infection control protocols, using approved disinfectants and personal protective equipment. In hospitality, room attendants prepare guest rooms. Training typically covers proper use of cleaning agents, safety data sheets, equipment operation, and ergonomics.

Tools and methods: Common tools include brooms, mops, vacuums, microfiber cloths, scrub brushes, and steam cleaners. Cleaning methods depend on the surface and contaminant and may involve sweeping, washing with detergents, rinsing, disinfection, and stain removal. Checklists are common in institutions to ensure coverage.

Products and standards: Cleaning products range from all-purpose cleaners and glass cleaners to degreasers and laundry detergents. They may contain surfactants, solvents, enzymes, and sanitizers. Safety labels, dilution instructions, and hazard information are provided in safety data sheets. Environmental and regulatory considerations promote safer formulations; many markets encourage green cleaning products with reduced toxicity and environmental impact.

Etymology and usage: The word derives from clean + -er. In some regions “cleaner” specifically refers to a professional domestic worker; in others it is used more broadly for cleaners and janitorial staff.
