Cleaning

Cleaning is the process of removing unwanted substances, such as dirt, infectious agents, and other impurities, from an object or environment.

Cleaning is often performed for aesthetic, hygienic, functional, safety, or environmental protection purposes.

Cleaning occurs in various commercial, domestic, personal, and environmental contexts, which differ in scale and requirements.

Cleaning is broadly achieved through mechanical action and/or chemical processes (usually solvation); many methods rely on a combination of mechanical and chemical action.

Methods include: Some items and materials require specialized cleaning techniques, due to their shape, size, location, or the material properties of the object and contaminants.
