Preventing Rust on Stainless Steel:
1. Use the Correct Cleaning Tools

cloths and plastic scouring pads .
2. Clean Along the Grain
Polishing lines or grain are visible on some stainless steels . Always scrub
parallel
to these visible
lines on stainless steel using a plastic scouring pad or soft cloth . If no lines are visible, use a soft
touch with a soft cloth or plastic scouring pad .
3. Use Alkaline, Alkaline Chlorinated, or Non-Chloride Containing Cleaners
While many traditional cleaners are loaded with chlorides, commercial suppliers are providing
an ever increasing choice of non-chloride cleaners . One of the best is
Noble Chemical Excel
Stainless Steel Cleaner
. 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 & Dry
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 the stainless steel .
7. NEVER USE HYDROCHLORIC ACID ON STAINLESS STEEL
8. Regularly Restore/Passivate Stainless Steel
