8 TIPS TO HELP PREVENT RUST ON STAINLESS STEEL
•
Maintain the Cleanliness of Your Equipment –
build-up of hard stains by cleaning frequently. Use
cleaners at the recommended strength (alkaline
chlorinated or non-chloride).
•
Use the Correct Cleaning Tools –
tools when cleaning your stainless steel products.
The stainless steel's passive layer will not be
harmed by soft cloths and plastic scouring pads.
•
Clean Along Polishing Lines –
are visible on some stainless steels. Always scrub
parallel to polishing lines when visible. Use a plastic
scouring pad or soft cloth when you cannot see the
grain.
•
Use Alkaline, Alkaline-Chlorinated or Non-Chloride
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.
•
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.
•
Never Use Hydrochloric Acid (Muriatic Acid) on
Stainless Steel –
Even diluted, hydrochloric acid
can cause corrosion, pitting and stress corrosion
cracking of stainless steel.

•
Water Treatment –
water when possible. Installation of certain filters
can remove corrosive and distasteful elements.
Salts in a properly maintained water softener can
also be to your advantage. Contact a treatment
specialist if you are not sure of the proper water
treatment.
•
Regularly Restore & Passivate Stainless Steel –
Stainless steel gets its stainless properties from
the protective chromium oxides on its surface.
If these oxides are removed by scouring, or by
reaction with harmful chemicals, then the iron in
the steel is exposed and can begin to oxidize, or
rust. Passivation is a chemical process that removes
free iron and other contaminants from the surface
of stainless steel, allowing the protective chromium
oxides to re-form.
