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 burnt deposits that do not respond to
the above procedure can usually be removed by rubbing the surface with SCOTCH-BRITE brand scouring
pads or STAINLESS scouring pads. DO NOT USE ORDINARY STEEL WOOL, as any particles left on the
surface will rust and further spoil the appearance of the finish. NEVER USE A WIRE BRUSH, STEEL
SCOURING PADS (EXCEPT STAINLESS), SCRAPER, FILE OR OTHER STEEL TOOLS. Surfaces that are
marred collect dirt more rapidly and become more difficult to clean. Marring also increases the possibility of
corrosive attack. Refinishing may then be required.
Darkened areas, called “heat tint,” sometimes appear on stainless steel surfaces where the area has been
subjected to excessive heat. These darkened areas are caused by thickening of the protective surface of the
stainless steel and are not harmful. Heat tint can normally be removed by the above cleaning techniques, but
tint which does not respond to that procedure calls for a vigorous scouring in the direction of the polish lines,
using SCOTCH-BRITE brand scouring pads or a STAINLESS scouring pad in combination with a powered
cleanser. Heat tint action may be lessened by not applying or by reducing, heat to equipment during slack
periods.
