Cleaning

Stainless steel equipment and fixtures must be cleaned on a regular basis to prevent them from rusting. A water wash is often sufficient for cleaning a stainless steel surface; hot water and steam can be used in special cases. Impurities and deposits that have adhered to the stainless steel surface can be removed by rubbing them with an emery cloth, for example.

The emery cloth must be non-ferrous. It is advisable to first try the treatment on a less noticeable part of the product.

A sink with rounded edges, removable washing arms, overflow protection pipe, pump screen, rubber curtains and strainer baskets are all easy to keep clean. The washing arms can be removed by simply releasing the latch locking mechanism. The aforementioned parts must be washed on a regular basis.

The pipe of the magnetic float must be cleaned and checked for fouling on a regular basis to ensure sufficient water supply to the pump. Washing with a brush from the outside and from the inside where accessible, for example, is sufficient.

The machine is designed to have enough room under it so as to be readily accessible with cleaning equipment so that it is easy to keep clean.

If the machine is to be out of service for a prolonged period of time, it must be washed thoroughly.

Detergents

Standard cleaning powders or power detergents such as soda, borax or sodium perborate can be used for cleaning stainless steel surfaces.

Alkaline solutions, such as soda, ammonia and diluted soda lye, can be used for dissolving grease. Acetone, petrol, alcohol and similar organic solvents can also be used for removing grease deposits or other water-insoluble matter.

Detergents that contain sulphuric or hydrochloric acid may not be used for cleaning stainless steel surfaces.

Disinfection

The most affordable disinfectant that is suitable for stainless steel is nitric acid; even mild concentration solutions have a bactericidal effect.

The sterilising agents used for disinfection often contain sodium hypochlorite or potassium hypochlorite. However, these substances are dangerous to stainless steel as they easily give rise to pitting corrosion. Other disinfectants that contain chlorine, such as chloramines, are also dangerous.
