In larger schools, sometimes clean crews are employed that take care of cleanliness.
Every day they sweep the corridors, wash the floors and throw out rubbish, while at specified intervals they also deal with window cleaning, fine grating of the dust and pasturing of the floors.
In the spring-summer and autumn period, the school area is also cleaned.
In the abrasive cleaning and cleaning of the floor, generally available cleaning and fragrances help, while the use of a vacuum cleaner makes it possible to reach all corners of the room.
All cleaning activities are carried out several times a month, usually at the end of the week, and more detailed cleaning is done before the visit of family members and friends.
All these buildings must be cleaned up well, and the equipment used in them must be arranged in such a way that they do not endanger the safety of people staying in a university building.Therefore, from time to time, university buildings include cleaning crews that clean up lecture rooms and sanitary and sports facilities.
Their tasks include grinding the dust, washing floors, removing spider webs that are being created, and disinfecting sanitary facilities.
