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 a day. Always thoroughly rinse
surfaces after using a cleaning agent and wipe
standing water as quickly as possible after rinsing.

USE AUTHORIZED COMBITHERM
CLEANER ONLY
Cleaning agents must be chloride-free compounds
and must not contain quaternary salts. Never use
hydrochloric acid (muriatic acid) on stainless steel
surfaces. Unauthorized cleaning agents may discolor
or harm interior surfaces of the oven. Read and
understand label and material safety data sheet
before using the oven cleaner.

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.
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.
