STAINLESS STEEL CARE AND CLEANING 

Use the proper tools- 

When cleaning  stainless steel surfaces;  take care to use non-abrasive 

tools. Soft cloths and plastic scouring pads will not harm the steel’s passive layer.  Stainless 

steel pads may be used but be sure to always scrub in the direction of the polishing lines. 

Clean with the polish lines- 

Some stainless steels come with visible polishing lines or “grain”.  

When visible lines are present, you should always scrub in a motion that is parallel to them.  

When the grain cannot be seen, play it safe and use a soft cloth or plastic scouring pad. 

Use alkaline, alkaline chlorinated or non-chloride containing cleaners- 

While many traditional 

cleaners are loaded with chlorides, there is now an ever increasing choice of non-chloride 

cleaners.  If you are not sure of your cleaner 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 also can attach stainless steel and cause pitting and 

rusting. 

Treat your water- 

Though this is not always practical, softening hard water can do much to 

reduce deposits.  There are certain filters that can be installed to remove corrosive elements.  

If you are not sure of the proper water treatment, call a treatment specialist.
