one location to another. Ask your municipal
water supplier for details about your local
water supply prior to installation. Presence of
sediment, silica, excess chlorides or other
dissolved solids may lead to a
recommendation for alternate form(s) of water
treatment. Test the water with the test strip
included with the steamer. Other factors
affecting steam generation are iron content,
amount of chloridation and dissolved gases.

STAINLESS STEEL EQUIPMENT

CARE AND CLEANING

Contrary to popular belief, stainless steels
ARE susceptible to rusting.

Corrosion on metals is everywhere. It is
recognized quickly on iron and steel as unsightly
yellow/orange rust. Such metals are called
“active” because they actively corrode in a natural
environment when their atoms combine with
oxygen to form rust.

Stainless steels are passive metals because
they contain other metals, like chromium,
nickel and manganese, that stabilize the
atoms. 400 series stainless steels are called
ferritic, contain chromium, and are magnetic;
300 series stainless steels are called
austenitic, containing chromium and nickel;
and 200 series stainless, also austenitic,
contains manganese, nitrogen and carbon.
Austenitic types of stainless are not magnetic,
and generally provide greater resistance to
corrosion than ferritic types.

With 12 to 30% chromium, an invisible passive
film covers the steel’s surface acting as a shield
against corrosion. As long as the film is intact
and not broken or contaminated, the metal is
passive and stainless. If the passive film of
stainless steel has been broken, equipment
starts to corrode and starts to rust.

Enemies of Stainless Steel

There are three basic things which can break
down stainless steel’s passivity layer and
allow corrosion to occur.

1. Mechanical abrasion.

Water comes out of the faucet in varying
degrees of hardness. Depending on what
part of the country you live in, you may have
hard or soft water. Hard water may leave
spots, and when heated leaves deposits
behind that if left to sit, will break down the
passive layer and rust stainless steel. Other
deposits from food preparation and service
must be properly removed.

Chlorides are found nearly everywhere. They
are in water, food and table salt. One of the
worst chloride perpetrators can come from
household and industrial cleaners.

So what does all this mean?
Don’t despair!

Here are a few steps that can help prevent
stainless steel rust.

1. Use the proper tools.

When cleaning stainless steel products,
use non-abrasive tools. Soft cloths and
plastic scouring pads will not harm steel’s
passive layer. Stainless steel pads also
can be used but the scrubbing motion
must be in the direction of the
manufacturers’ polishing marks.

2. Clean with the polish lines.

Some stainless steel comes with visible
polishing lines or grain. When visible lines
are present, always scrub in a motion
parallel to the lines. When the grain cannot
be seen, play it safe and use a soft cloth or
plastic scouring pad.

3. Use alkaline, alkaline chlorinated or
non-chloride containing cleaners.

2. Deposits and water.

3. Chlorides.

Mechanical abrasion means those things that
will scratch a steel surface. Steel pads, wire
brushes and scrapers are prime examples.

While many traditional cleaners are loaded
with chlorides, the industry is providing an
ever-increasing choice of non-chloride
cleaners. If you are not sure of chloride
content in the cleaner used, contact your
cleaning supplier. If your present cleaner
contains chlorides, ask your supplier if
they have an alternative. Avoid cleaners
containing quaternary salts; it also can
attack stainless steel and cause pitting
and rusting.

— 15 —

C24EO SERIES STEAMER

4. Treat your water.

Though this is not always practical,
softening hard water can do much to
reduce deposits. There are certain filters
that can be installed to remove distasteful
and corrosive elements. To insure proper
water treatment, call a treatment specialist.

5. Keep your food equipment clean.

Use alkaline, alkaline chlorinated or non­chloride cleaners at recommended
strength. Clean frequently to avoid build­up of hard stubborn stains. If you boil water
in stainless steel equipment, remember
the single most likely cause of damage is
chlorides in the water. Heating cleaners
that contain chlorides have a similar effect.

6. Rinse, rinse, rinse.

If chlorinated cleaners are used, rinse and
wipe equipment and supplies dry
immediately. The sooner you wipe off
standing water, especially when it contains
cleaning agents, the better. After wiping
equipment down, allow it to air dry; oxygen
helps maintain the stainless steel’s
passivity film.

7. Never use hydrochloric acid (muriatic
acid) on stainless steel.

8. Regularly restore/passivate stainless
steel.

Review

1. Stainless steels rust when passivity (film-shield) breaks down as a result of scrapes,
scratches, deposits and chlorides.

2 Stainless steel rust starts with pits and cracks.

3. Use the proper tools. Do not use steel pads, wire brushes or scrapers to clean stainless steel.

4. Use non-chlorinated cleaners at recommended concentrations. Use only chloride-free cleaners.

5. Soften your water. Use filters and softeners whenever possible.

6. Wipe off cleaning agent(s) and standing water as soon as possible. Prolonged contact causes
eventual problems.

To learn more about chloride-stress corrosion and how to prevent it, contact the equipment
manufacturer or cleaning material supplier.

saved. Liquids can be collected in a solid 12" x
20" pan placed under a perforated pan.

Perforated pans are used for frankfurters,
wieners and similar items when juices do not
need to be preserved. Solid pans are good for
cooking puddings, rice, and hot breakfast
cereals. Vegetables and fruits are cooked in
solid pans in their own juice. Meats and poultry
are cooked in solid pans to preserve their juice
or retain broth.

Canned foods can be heated in their opened
cans (cans placed in 12" x 20" solid pans) or
the contents may be poured into solid pans.
DO NOT place unopened cans in the steamer.

COOKING GUIDELINES

The steamer cooks vegetables, frankfurters,
eggs in their shells, and certain other meats or
food items at atmospheric pressure.

These cooking guidelines are suggestions only.
You should experiment with your food products
to determine the cooking times that will give you
the best results. Variables which affect cooking
time include size, weight, thickness of foods,
temperature, density, previous condition of the
foods (fresh, pre-blanched or frozen) and degree
of doneness desired.

Frozen Food Items

Separate frozen foods into smaller pieces to
allow more efficient cooking.

Use a pan cover for precooked frozen dishes
that cannot be cooked in the covered
containers in which they are packed if they
require more than 15 minutes of cooking time.
When a cover is used, approximately one­third additional cooking time is necessary.

Cooking time for frozen foods depends on
the amount of defrosting required. If time
permits, allow frozen foods to partially thaw
overnight in a refrigerator. This will reduce
their cooking time.
