3.4 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.
IMPORTANT
Acid solutions, salty solutions, disinfectants and some sterilizing solutions
(hypochlorites, tetravalent ammonia salts, iodine compounds, nitric acid and
others), must be AVOIDED, once they cannot remain for long in contact
with the stainless steel.
