Cleaning guidelines
Further information on stainless steel surfaces:
● The surface should be properly ventilated.
● Keep the surface clean. Remove cleaners and food residue immediately. Make sure that
foodstuff does not splash back into the production process.
● If mechanical cleaning is necessary, do not use cleaning equipment made of metal.
– Use brushes made of plastic or natural materials, or a microfiber pad.
– Use plenty of water to clean the surface.
– Remove cleaners without leaving any residue, including corners and confined areas.
● Make sure surface is not damaged: Do not damage the device during operation, or by
cleaning or repairing it using hard objects, in particular objects made of non-stainless
steel material.
● Avoid contact of the surface with corrosive parts: Extraneous rust from water lines, file
chips, residue of wire brushes or steel wool and rust films have a corrosive effect on parts
made of stainless steel.
– Remove any stains or extraneous rust immediately.
– Remove new rust spots with a mild abrasive detergent in order to prevent any further
corrosion.
– Rinse the part thoroughly after you cleaned it.
