PROTECTING STAINLESS STEEL SURFACES
I
t is important to guard against
c
orrosion in the care of
s
tainless steel surfaces.
H
arsh, corrosive, or
i
nappropriate 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 a day.
Always thoroughly rinse surfaces after using a
cleaning agent and wipe standing water as quickly
as possible after rinsing.
CLEANING AGENTS
U
se non-abrasive cleaning products designed for
u
se on stainless steel surfaces. Cleaning agents
m
ust be chloride-free compounds and must not
c
ontain quaternary salts. Never use hydrochloric
a
cid (muriatic acid) on stainless steel surfaces.
Always use the proper cleaning agent at the
manufacturer's recommended strength.
Contact your local cleaning supplier for
product recommendations.
CLEANING MATERIALS
The cleaning function can usually be accomplished
with the proper cleaning agent and a soft, clean
cloth. When more aggressive methods must be
employed, use a non-abrasive scouring pad on
difficult 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.
