How do you keep school library clean?

Lux it every second day, every day if you are in a school with a cleaner. At the start of every day and after every break check all of the books are upright and neat and tidy. Every second day run checks for books in the wrong place, everyday if you have another worker with you. 1ce a week at least clean the front and sides of the books unless you are in a big library in which case do it every time a book is returned- if durasealed!!!!
