What is the term for the physical removal of all visible dust, soil, and other foreign materials from an object?

The term that refers to the physical removal of all visible dust, soil, and other foreign materials from an object is cleaning. Cleaning involves using soap, detergent, or other cleaning agents to remove dirt and impurities from surfaces, ensuring that the area is thoroughly free from visible contaminants.

Sanitizing, while closely related, specifically aims to reduce the number of microorganisms to safe levels as defined by public health standards but does not emphasize the removal of visible dirt or debris. Disinfecting goes a step further by eliminating most germs, viruses, and bacteria on surfaces, typically using stronger agents or chemicals, yet it may still leave behind dust or visible debris. Polishing is focused on enhancing the appearance of an object by providing a shine and is not primarily aimed at removing dirt or contaminants. Therefore, cleaning is the most appropriate term that captures the complete removal of visible impurities.
