Preventing Rust on Stainless Steel:

1. Use the Correct Cleaning Tools

Use non-abrasive tools when cleaning . The stainless steel's outer layer will not be harmed by soft

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
