CAUTION:
Do not use any steel wool, abrasive or chlorine based products to clean stainless steel surfaces. Please
ensure that you use appropriate products when cleaning and polishing your True unit. Cleaners containing chlorine
must not be used as these will attack the stainless steel causing damage and in some cases corrosion. Your supplier of
cleaning products should be able to advise you of the products suitable to keep your True unit looking like new.

Stainless Steel Opponents
There are three basic things which can break down your stainless steel’s passivity layer and allow
corrosion to rear its ugly head.
1) Scratches from wire brushes, scrapers, and steel pads are just a few examples of items that can be
abrasive to stainless steel’s surface.
2) Deposits left on your stainless steel can leave spots. You may have hard or soft water depending on
what part of the country you live in. Hard water can leave spots. Hard water that is heated can
leave deposits if left to sit too long. These deposits can cause the passive layer to break down and
rust your stainless steel. All deposits left from food prep or service should be removed as soon 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 that can help prevent rust on stainless steel:
1. Using 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. Step 2 tells you how to find the polishing marks.
2. Cleaning along the polish lines
Polishing lines or “grain” are visible on some stainless steels. Always scrub parallel to visible lines on some
stainless steels. Use a plastic scouring pad or soft cloth when you cannot see the grain.
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 you are not sure of your cleaner’s chloride content contact your cleaner supplier.
If they tell you that your present cleaner contains chlorides, ask if they have an alternative. Avoid cleaners
containing quaternary salts as they can attack stainless steel, causing pitting and rusting.
4. Water Treatment
To reduce deposits, soften the hard water when possible. Installation of certain filters can remove corrosive
and distasteful elements. Salts in a properly maintained water softener can be to your advantage. Contact a
treatment specialist if you are not sure of the proper water treatment.
5. Maintaining the cleanliness of your food equipment
Use cleaners at recommended strength (alkaline, alkaline chlorinated or non-chloride). Avoid build-up of hard
stains by cleaning frequently. When boiling water with your stainless steel equipment, the single most likely
cause of damage is chlorides in the water. Heating any cleaners containing chlorides will have the same
damaging effects.
6. Rinse
When using chlorinated cleaners you must rinse and wipe dry immediately. It is better to wipe standing
cleaning agents and water as soon as possible. Allow the stainless steel equipment to air dry. Oxygen helps
maintain the passivity film on stainless steel.
7. Hydrochloric acid (muriatic acid) should never be used on stainless steel
8. Regularly restore/passivate stainless steel
