Stainless Steel Care and Cleaning
To prevent discoloration or rust on stainless steel several
important steps need to be taken. First, we need to
understand the properties of stainless steel. Stainless
steel contains 70- 80% iron, which will rust. It also
contains 12-30% chromium, which forms an invisible
passive film over the steel's surface, which acts as a
shield against corrosion. As long as the protective layer
is intact, the metal is still stainless. If the film is broken or
contaminated, outside elements can begin to breakdown
the steel and begin to form discoloration or rust. Proper
cleaning of stainless steel requires soft cloths or plastic
scouring pads.
NEVER USE STEEL PADS, WIRE BRUSHES OR
SCRAPERS!
Cleaning solutions need to be alkaline based or non-
chloride cleaners. Any cleaner containing chlorides
will damage the protective film of the stainless steel.
Chlorides are also commonly found in hard water,
salts, and household and industrial cleaners. If cleaners
containing chlorides are used be sure to rinse repeatedly
and dry thoroughly. Routine cleaning of stainless steel
can be done with soap and water. Extreme stains or
grease should be cleaned with a non-abrasive cleaner
and plastic scrub pad. Always rub with the grain of the
steel. There are stainless steel cleaners available which
can restore and preserve the finish of the steels protective
layer. Early signs of stainless steel breakdown are small
pits and cracks. If this has begun, clean thoroughly and
start to apply stainless steel cleaners in attempt to restore
the passivity of the steel.
Never use an acid based cleaning solution!
Many food products have an acidic content,
which can deteriorate the finish. Be sure to
CAUTION
clean the stainless steel surfaces of ALL food
products. Common items include, tomatoes,
peppers and other vegetables.
