Eight Steps that can help prevent rust on stainless steel:
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 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 chloride content contact the cleaner supplier. If
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. Installation of certain filters can be an advantage. Contact a
treatment specialist about proper water treatment.
5. Maintain 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 standing cleaning agents and water
as soon as possible. All 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.
