4.2 THE MOST COMMON CAUSES OF CORROSION:
Floor cleaning
The cleaning of tiles (after work, or during regular service) is often carried out with very aggressive
products. If the product is sprayed under pressure without caution, the splashes beneath the appliances
cause corrosion of bottoms and panels.
Even worst, the vapour from these products, if the premises are not immediately and forcefully
ventilated, fall on the equipment and can extend the corrosion to all surfaces.
Inappropriate cleaning products (Bleach, Acids, Soda)
If products, such as Bleach, acids or soda dilutions,... (all products not especially designed for use
on stainless steels) are used, an irreversible attack occurs on the stainless steel surfaces.
Cleaning product applied at too high temperature
All cleaning products become more aggressive if applied to a hot surface. As a general rule, the
temperature must not be higher than 60°C, not to attack the stainless steel in an irreversible way
(Blackening of surfaces...).
Cleaning product not properly rinsed
If the interior surfaces once cleaned are not thoroughly rinsed in order to eliminate any trace of
cleaning product, the latter, with time, will carry on its action and risk provoking corrosion.
Even worst, if this interior surface reaches temperatures higher than 60°C (Inside an oven, a well,
cooking-top...), the problems mentioned previously, will inevitably occur.
Stagnation of cleaning products
In the same way, any zone that can retain some cleaning products, particularly gutters, drains of
combi ovens, taps,... must be rinsed thoroughly and abundantly. (Use a nylon brush to strengthen the
rinse action with clear water).
Salt concentration
Salt, which is an ordinary element in cookery, often causes attacks (pinholes) in stainless steel.
Spillage on the cooking surfaces must be cleaned immediately
Special case of boiling in a boiling pan:
Salting the water by throwing cooking salt into the tank, presents risk: The cooking salt, by setting at
the bottom of the tank, may well, before dissolving, corrode the bottom in an irreversible way, if the
operation is frequent.
Water should be stirred until the salt has completely dissolved, or table salt should be used.
Intensive use in brined environment
Certain products such as sauerkraut (acid juices), seafood (presence of salt), and generally
speaking, brine should be given particular attention. In case of occasional use and standard equipment
this does not pose problem, if they are thoroughly and systematically cleaned after each use.
In case of intensive treatment, cooking equipment (Cooking ovens, boiling pans...) should be chosen
with steel specifically designed for this type of operation.
