Exterior cleaning

Exterior cleaning is the process of cleaning a building's exterior, including the restoration of good hygiene or removal of litter or dirt. Not to be confused with interior cleaning (e.g., office cleaning), exterior cleaning draws on aspects of environmental care, architecture preservation, and psychological well-being, in addition to traditional cleaning. In some jurisdictions, exterior cleaners must be licensed to practice, e.g. window cleaners require a license to operate in Scotland.
