Stainless Steel Care and Cleaning
Stainless steel contains 70-80% iron, which will
rust. It also contains 12-30% chromium, which
forms an invisible passive film over the steel
surface and acts as a shield against corrosion.
As long as the protective film remains intact,
the metal will not corrode. However, if the film
is broken or contaminated, outside elements
can begin to breakdown the steel and begin to
form rust or discoloration. To prevent rust and
discoloration on stainless steel, several
important steps need to be taken.
CAUTION: Never use steel wool pads or
wire brushes or scrapers. Avoid
cleaning solutions that contain
alkaline or chloride.
Use alkaline based or non-chloride cleaning
solutions. Anything containing chloride will
damage the protective film on stainless steel.
Chlorides are found in household and industrial
cleaners and also in hard water and salts. If a
chloride or alkaline cleaner has been used,
rinse repeatedly and dry thoroughly.
Always use only soft cloths or plastic scouring
pads. For routine cleaning, use warm soapy
water. For stubborn stains use a non-abrasive
cleanser. For heavy grease use a degreaser.
For best results, rub with the grain of the steel.
Pitting and cracking are early signs of stainless
steel breakdown. But special stainless steel
cleaners can restore and preserve the protective
film. If signs of breakdown appear, thoroughly
clean and dry all surfaces. Begin regular
application of a high quality stainless steel
cleaner according to the manufacturer's
instructions. Again, always rub with the grain of
the steel for best results.
