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 after using a
cleaning agent and wipe standing water as quickly
as possible after 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 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. Failure to observe this
precaution will void the warranty.

To prevent SERIOUS INJURY,
DEATH, or PROPERTY DAMAGE:
The appliance must be cleaned
thoroughly to avoid deposits of
grease and or food residues inside
the appliance that may catch fi re. If
fat deposits and/or food waste inside
the appliance ignite, shut down the
appliance immediately and keep the
appliance door closed to extinguish
the fi re. If further extinguishing is
required, disconnect the appliance
from the main power and use a fi re
extinguisher (do not use water to
extinguish a grease fi re!). Failure
to clean the appliance properly
invalidates the warranty and relieves
Alto-Shaam of all liability.
