It works well on ornaments and other stainless steel, too. What about stainless steel refrigerator doors? These doors are usually made of brushed steel but caution should be used. Aggressive rubbing on refrigerator doors will polish the brushed look and make it look a bit different. In some cases, the stainless steel may not be stainless steel, therefore the use of the polish will make the metal shine. There are instructions that come with the appliance and should be followed.
