3.2.3 Cautions with Stainless Steel:
The Stainless Steel may present rust signs, which ARE ALWAYS CAUSED BY
EXTERNAL AGENTS, especially when the cleaning or sanitization 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 formation of a very
thin protective coat. This protective coat is formed through the whole surface of the
steel, blocking the action of external corrosive agents.
When the protective 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 after using the equipment. For
such end, use water, neutral soap or detergent, and clean the equipment with a soft
cloth or a nylon sponge. Then rinse it with plain running water, and dry
immediately with a soft 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.
Acid solutions, salty solutions, disinfectants and some sterilizing
solutions ( hypochlorite s, 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 attack the stainless steel due to the CHLORINE on its
composition, causing corrosion spots (pitting).
Even detergents used in domestic 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 wool and carbon steel brushes, besides scratching the
surface and compromising the stainless steel protection, leave particles that rust
and react contaminating the stainless steel. That is why such products must not be
used for cleaning and sanitization. Scrapings made with sharp instruments or
similar must also be avoided.
Main substances that cause stainless steel corrosion:
Dust, grease, acid solutions such as vinegar, fruit juices, etc., saltern
solutions (brine), blood, detergents (except for the neutral ones), common steel
particles, residue of sponges or common steel wool, and also other abrasives.
