For dishwashers in catering are typically used special detergents. Such detergents may be either in solid form or liquid (in different volume cans). Professional detergents may be intended for dishes made of various materials (porcelain, glass etc). For example, professional detergents for glass washing machines have pH 9 and contain protective agents, herewith, there is no chloro in them, which avoids unpleasant odor and damagesof the surface. High concentration and professional detergents require careful compliance with all safety procedures. Together with professional detergents are also used rinsers, which keep dishes spotless so you don't have to spend too much time on wiping and polishing. The concentration of professional detergent directly affects the result, and its supply in dishwashers is usually made through the use of rinse aid and detergents dispenser,so that avoids excessive foaming and provides an opportunity to achieve the required quality of washing.
