CASTER MAINTENANCE
Wipe casters with a damp cloth monthly to prevent
corrosion.
NOTE: The power switch must be turned to OFF and
the unit disconnected from the power source
whenever performing service, maintenance functions
or cleaning the refrigerated area.
REFRIGERATORS
The interior and exterior can be cleaned using soap
and warm water. If this isn’t sufficient, try ammonia and
water or a nonabrasive liquid cleaner. When cleaning
the exterior, always rub with the “grain” of the stainless
steel to avoid marring the finish. Do not use an
abrasive cleaner because it will scratch the stainless
steel and can damage the breaker strips and gaskets.
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 break down 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!
