5 | Refrigerated Chef Base Instruction Manual
CLEANING THE INTERIOR OF UNIT
• When cleaning the cabinet interior, use a solvent of warm water and mild soap.
• Do not use steel wool, caustic soap, abrasive cleaners, or bleach that may damage the stainless steel
surface.
• Wash door gaskets on a regular basis, preferably weekly. Simply remove door gasket from the frame
of the door, soak in warm water and soap for thirty (30) minutes, dry with soft cloth, and replace.
• Check door gaskets for proper seal after they are replaced.
• Periodically remove the shelves and pilasters from the unit and clean them with mild soap and
warm water. To remove the pilasters, rst remove the shelves and shelf brackets. Then, simply lift the
pilaster up and out.
STAINLESS STEEL CARE AND CLEANING
• CAUTION: Do not use any steel wool, abrasive or chlorine-based products to clean stainless
steel surfaces.
Recommended cleaners for stainless steel:
• Soap, ammonia, and detergent medallion applied with a soft cloth or sponge for routine cleaning.
• Arcal 20, Loc-O-Nu Ecoshine provide a barrier lm for ngerprints and smears.
• Cameo, Talc, Zud First Impression is for stubborn stains and discoloration.
• Rub in the direction of polish lines.
• Easy-Off and De-Grease It oven Aid are excellent for removals on all nishes for grease-fatty acids,
blood, and burnt-on foods.
• Any good commercial detergent can be applied with a sponge or soft cloth to remove grease
and oil.
• Benet, Super Sheen, Sheila Shine are good for restoration/passivation.
Three things that can break down stainless steel’s passivity layer and allow corrosion to occur:
1. Scratches from wire brushes, metal scrapers and steel pads are just a few examples of items that can
be abrasive to stainless steel’s surface.
2. Deposits left on stainless steel can leave spots. Hard water can leave spots. Hard water that is heated
can leave deposits if left to sit for too long. These deposits can cause the passive layer to break down
and rust stainless steel. All deposits left from food prep or service should be removed as quickly as
possible.
3. Chlorides are present in table salt, food and water. Household and industrial cleaners are the worst
type of chlorides to use.
8 Steps to help prevent stainless steel from rusting:
1. Use the correct cleaning tools. Use non-abrasive tools when cleaning your stainless steel products.
The stainless steel’s passive layer will not be harmed by soft cloths and plastic scouring pads.
2. Clean along the polish lines. Polish lines or grain are visible on some stainless steel. Always scrub
parallel to visible lines. Use a plastic scouring pad or soft cloth when the grain is not visible.
3. Use alkaline, alkaline chlorinated or non-chloride containing cleaners. While many traditional
cleaners are loaded with chlorides, the industry is providing an ever-increasing choice of non-
chloride cleaners. If unsure of the chloride content, contact the cleaner supplier. If the present
cleaner contains chlorides, ask for an alternative. Avoid cleaners containing quaternary salts as they
can attack stainless steel, causing pitting and rusting.
4. Water treatment. To reduce deposits, use soft water whenever possible. The installation of certain
lters can be an advantage. Contact a treatment specialist about proper water treatment.
5. Maintain the cleanliness of food equipment. Use cleaners at recommended strength (alkaline,
alkaline chlorinated or non-chloride). Avoid buildup of hard stains by cleaning frequently
6. When using chlorinated cleaners, you must rinse and wipe dry immediately. It is better to wipe
6 | Refrigerated Chef Base Instruction Manual
standing cleaning agents and water as soon as possible. All stainless steel equipment should be
allowed to air dry. Oxygen helps maintain the passivity lm on stainless steel.
7. Hydrochloric acid (muriatic acid) should never be used on stainless steel.
8. Regularly restore/passivate stainless steel.
