6.0 CLEANING INSTRUCTIONS (Continued)
TO REMOVE HEAT TINT: Darkened areas 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 is not harmful. Heat tint can
normally be removed by the foregoing, but tint which does not respond to this procedure calls
for a vigorous scouring in the direction of the polish lines using SCOTCH-BRITE™ scouring
pads or a STAINLESS scouring pad in combination with a powdered cleanser. Heat tint action
may be lessened by not applying or by reducing heat to equipment during slack periods.
All food contact surfaces must be thoroughly drained and flushed prior to cooking in the kettle.
CONTROL PANEL: The textured control panel should be cleaned with warm water and mild
soap. Never use an abrasive cloth or steel wool. Never use cleaning solvents with a
hydrocarbon base.
