Principles for working with stainless steel devices
The surface of stainless steel equipment must always be kept clean and open to the air.
–
Stainless steel parts should only be treated with alkaline cleaning agents that contain small amounts
of acid-free oil and not with acidic cleaning agents. Ingredients according to the manufacturer’s data
in accordance with EU recommendations:
less than 5 % non-ionic surfactants,
more than 30 % aliphatic hydrocarbons.
–
Do not use bleaching cleaning agents or cleaning agents that contain chlorine.
–
Remove layers of lime scale, grease, starch, and protein regularly by cleaning. Corrosion can form
under these layers due to lack of circulating air.
Descaling can be performed with
10 % acetic acid,
10 % phosphoric acid, or
with commercially available descaling agents.
–
Parts made of stainless steel must not be in contact with concentrated acids, salts, spices, etc. for
prolonged periods of time.
Acid vapors that form during tile cleaning promote corrosion. Rinse contact surfaces with fresh water
and wipe them dry.
–
Fresh rust spots can be removed with mild scouring agents or fine abrasive paper. More stubborn rust
spots can be washed with a warm 2 to 5 % oxalic acid solution.
If these cleaning agents fail, treatment with 10 % nitric acid is recommended. Because of the hazards
involved, this treatment must only be performed by technically trained personnel in accordance with
current regulations.
