To remove grease and food splatter or condensed vapors that have hardened on the equipment, apply
cleaners to a damp cloth or sponge and rub cleanser on the metal in the direction of the polished lines on the
metal. Rubbing cleanser as gently as possible in the direction of the polished lines will not mar the finish of
the stainless steel. NEVER RUB WITH A CIRCULAR MOTION. Soil and burned on deposits which do not
respond to the above procedure can usually be removed by rubbing the surface with SCOTCH-BRITE
scouring pads or STAINLESS scouring pads.
a wire brush, steel or abrasive scouring pads (except stainless), scraper, file or other steel
tools. Surfaces which are marred collect dirt more rapidly and become more difficult to clean. Marring also
increases the possibility of corrosive attack.
