MAINTENANCE AND CLEANING 

These units require very little maintenance. They should be cleaned periodically to keep them 
running efficiently. Use the cleaning agents and suggestions below for best results.  

If ¼ to ½ inch of frost accumulates or if the unit will not maintain proper temperature, it should 
be defrosted per the procedure on page 14.

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.
