It is important to guard against corrosion 

in the care of stainless steel 

surfaces.  Harsh, corrosive, 

or inappropriate chemicals 

can completely destroy the 
protective surface layer 

of stainless steel.  Abrasive 

pads, steel wool, or metal implements will abrade 
surfaces causing damage to this protective coating 
and will eventually result in areas of corrosion.  
Even water, particularly hard water that contains 
high to moderate concentrations of chloride, will 
cause oxidation and pitting that result in rust 
and corrosion.  In addition, many acidic foods 
spilled and left to remain on metal surfaces are 
contributing factors that will corrode surfaces.

 

Proper cleaning agents, materials, and 

methods are vital to maintaining the appearance 
and life of this appliance.  Spilled foods should be 
removed and the area wiped as soon as possible 
but at the very least, a minimum of once a day.  
Always thoroughly rinse surfaces after using a 
cleaning agent and wipe standing water as quickly 
as possible after rinsing.

use non-abrasive cleaning products designed for 
use on stainless steel surfaces.  Cleaning agents 
must be chloride-free compounds and must not 
contain quaternary salts.  Never use hydrochloric 
acid (muriatic acid) on stainless steel surfaces.  
Always use the proper cleaning agent at the 
manufacturer's recommended strength.  
Contact your local cleaning supplier for 
product recommendations.

The cleaning function can usually be accomplished 
with the proper cleaning agent and a soft, clean 
cloth.  When more aggressive methods must be 
employed, use a non-abrasive scouring pad on 
difficult areas and make certain to scrub with the 
visible grain of surface metal to avoid surface 
scratches.  Never use wire brushes, metal scouring 
pads, or scrapers to remove food residue.
