Stainless Steel Care and Cleaning
To prevent discoloration or rust on stainless steel, several important steps need to be
taken. 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 break down the
steel and begin to form rust or discoloration. Proper cleaning of stainless steel requires
soft cloths or plastic scouring pads,
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
upon completion.
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. It is al-
ways good
to rub with the grain of the steel. There are also stainless steel cleaners avail-
able which can restore and preserve the finish of the steels protective layer.
Early signs of stainless steel breakdown can consist of 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.
Gasket Maintenance
Gaskets require regular cleaning to prevent mold and mildew build up and also to keep
the elasticity of the gasket. Gasket cleaning can be done with the use of warm soapy
water. Avoid full strength cleaning products on gaskets as this can cause them to be-
come brittle and prevent proper seals. Also, never use sharp tools or knives to scrape
or clean the gasket which could possibly tear the gasket. Gaskets can easily be re-
placed and do not require the use of tools or authorized service persons, The gaskets
are "Dart" style and can be pulled out of the groove in the door and new gaskets can
be "pressed" back into place.

Never use an acid based cleaning solution. Many food products have
an acidic content which can deteriorate the nish. Be sure to clean
the stainless steel surfaces of ALL food products. C ommon items in-
clude, tomatoes, peppers and other vegetables.
