By definition, cleaning is the removal of visible and invisible dirt (organic matt, dust, bacteria, etc.) from an object using water and special products (soap or detergent). The main purpose of cleaning is hygiene and cleanliness. It is necessary before disinfecting because if the soiled objects are not cleaned, the elimination of unwanted materials will be difficult. Cleaning is important in everyday life because it not only keeps places or objects clean but also preserves human health.
