Further damages can occur due to:
§
extraneous rust (e.g. from other components, tools or rust film)
§
iron particles (e.g. grinding dust)
§
contact with non-ferrous metals (element formation)
§
lack of oxygen (e.g. no admission of air, low-oxygen water).
General working principles for the handling of appliances made of "refined stainless steel":
§
Always keep the surface of appliances made from stainless steel clean and accessible to the air.
§
Use cleaning agents suitable for stainless steel. No bleaching and chloride-containing cleaning
agents should be used.
§
Remove layers of lime scale, grease, starch and egg-white daily by cleaning. Corrosion can occur
underneath these layers due to lack of air admission.
§
After each cleaning operation remove all cleaning agent residues by rinsing thoroughly with copious
fresh water. Afterwards, the surface should be thoroughly dried.
§
Do not bring parts made of stainless steel into contact with substances such as concentrated acids,
seasonings and salts for longer than is absolutely necessary. Acid fumes which generate during
cleaning of tiles also promote the corrosion of "refined stainless steel".
§
Avoid damaging the surface of the stainless steel, particularly by metals other than stainless steel.
§
Residues of extraneous metals produce extremely small amounts of chemical elements which can
cause corrosion. In any case, contact with iron and steel should be avoided because that leads to ex-
traneous rust. If stainless steel comes into contact with iron (steel wool, steel particles from pipes, wa-
ter containing iron), this can be a trigger for corrosion. Therefore, for mechanical cleaning use exclu-
sively refined steel wool or brushes with natural, plastics or refined steel bristles. Steel wool or brush-
es with unalloyed steel lead to extraneous rust due to abrasion.
