3.4 Cauons with Stainless Steels
The Stainless Steel may present rust signs, which ARE ALWAYS CAUSED BY EXTERNAL
AGENTS, especially when the cleaning or sanizaon is not constant and appropriate.
The Stainless Steel resistance towards corrosion is mainly due to the presence of chrome,
which in contact with oxygen allows the formaon of a very thin protecve coat. This
protecve coat is formed through the whole surface of the steel, blocking the acon of
external corrosive agents.
When the protecve coat is broken, the corrosion process begins, being possible to avoid
it by means of constant and adequate cleaning.
Cleaning must always be done immediately aer using the equipment. For purpose, use
water, neutral soap or detergent, and clean the equipment with a so cloth or a nylon
sponge. Then rinse it with plain running water, and dry immediately with a so cloth, this
way avoiding humidity on surfaces and especially on gaps.
The rinsing and drying processes are extremely important to prevent stains and corrosion
from arising.
IMPORTANT
Acid soluons, salty soluons, disinfectants and some sterilizing soluons
(hypochlorites, tetravalent ammonia salts, iodine compounds, nitric acid and
others), must be AVOIDED, once it cannot remain for long in contact with the
stainless steel.
These substances aack the stainless steel due to the CHLORINE on its composion,
causing corrosion spots (ping).
Even detergents used in domesc cleaning must not remain in contact with the stainless
steel longer than the necessary, being mandatory to remove it with plain water and then
dry the surface completely.
Use of abrasives:
Sponges or steel wools and carbon steel brushes, besides scratching the surface
and compromising the stainless steel protecon, leave parcles that rust and react
contaminang the stainless steel. That is why such products must not be used for cleaning
and sanizaon. Scrapings made with sharp instruments or similar must also be avoided.
Main substances that cause stainless steel corrosion:
Dust, grease, acid soluons such as vinegar, fruit juices, etc., saltern soluons (brine),
blood, detergents (except for the neutral ones), common steel parcles, residue of sponges
or common steel wool, and also other abrasives.

17
Observaon:
It is necessary to preheat the oven and such procedure may take 10 minutes to heat. The
oven temperature will be one programmed in the controller by the operator being able to
vary from 1 to 5 degrees (+ or -).
The mes and temperatures here presented are guides that must be adjusted according
the recipes and sizes of each product and preferences of the client.
