Periodically clean the surface of the hood with hot soapy water and a clean cotton cloth. Do not use corrosive or abrasive detergent, or steel wool/scouring pads which will scratch and damage the surface. Do not use products containing chlorine bleach or citrus-based cleaners.
For heavier soil use a liquid degreaser.
After cleaning, you may use non-abrasive stainless steel polish or cleaners to polish and buff out the stainless luster and grain. Using a clean microfiber or cotton cloth, scrub lightly and with the grain.
