Exterior cleaning is the process of cleaning a building's exterior part including the restoration of hygiene or removal of litter and/or dirt on the outside of the building. It is not to be confused with interior cleaning, the act of cleaning inside a building.
The procedure for maintaining a building's exterior includes the removal of filth and restoration of cleanliness, as well as the elimination of litter and other unwanted materials on the outer surface of the edifice. This is distinct from interior maintenance, which focuses on cleaning inside a structure.
