Cleaning involves using cleaning agents to remove food, soil, or other substances from surfaces like dishes, glasses, and cutting boards. The right cleaning agent must be selected based on the surface and intended use, as some cleaners should not be used on food contact surfaces due to the risk of leaving unsafe residues. Common cleaning compounds include detergents, solvent cleaners, acid cleaners, and abrasives, each suited to removing different types of soils while avoiding damage to surfaces.
