Cleaning and Preventative Maintenance
Protecting Stainless Steel Surfaces
It is important to guard against corrosion
in the care of stainless steel
surfaces. Harsh, corrosive,
or inappropriate chemicals
can completely destroy the
protective surface layer of
stainless steel. Abrasive pads,
steel wool, or metal implements
will abrade surfaces causing damage to this protective
coating and will eventually result in areas of corrosion.
Even water, particularly hard water that contains high
to moderate concentrations of chloride, will cause
oxidation and pitting that result in rust and corrosion.
In addition, many acidic foods spilled and left to
remain on metal surfaces are contributing factors that
will corrode surfaces.
Proper cleaning agents, materials, and methods are
vital to maintaining the appearance and life of this
appliance. Spilled foods should be removed and the
area wiped as soon as possible but at the very least,
a minimum of once per day. Always thoroughly
rinse surfaces aft er using a cleaning agent and wipe
standing water as quickly as possible aft er rinsing.
Cleaning Agents
Use non-abrasive cleaning products designed for
use on stainless steel surfaces. Cleaning agents must
be chloride-free compounds and must not contain
quaternary salts. Never use hydrochloric acid (muriatic
acid) on stainless steel surfaces. Failure to observe
this precaution will void the warranty. Always use
the proper cleaning agent at the manufacturer's
recommended strength. Contact your local cleaning
supplier for product recommendations.
Cleaning Materials
Cleaning can usually be accomplished with the
proper cleaning agent and a soft , clean cloth. When
more aggressive methods are needed, use a non-
abrasive scouring pad on diffi cult areas and make
certain to scrub with the visible grain of surface metal
to avoid surface scratches. Never use wire brushes,
metal scouring pads, or scrapers to remove food
residue. Failure to observe this precaution will void
the warranty.
NOTICE
To protect stainless steel surfaces,
completely avoid the use of abrasive
cleaning compounds, chloride based
cleaners, or cleaners containing
quaternary salts.
Never use hydrochloric
acid (muriatic acid) on stainless steel.
Never use wire brushes, metal scouring
pads or scrapers.

:
The appliance must be cleaned thoroughly
to avoid deposits of grease and or food
residue inside the appliance that may
