Stainless steel hoods should be washed regularly with a clean cloth, warm water and mild soap or dish detergent. Clean in the direction of the polish lines. Rinse well with clear water and wipe dry immediately. You may wish to apply light oil used for furniture polishing to emphasize its bright finish. Wiping regularly with mild soap/detergent and warm water should protect painted hood surfaces. Be cautious about using "New and Improved" cleaning agents. Your hood is installed over hot cooking equipment. Most chemicals found in cleaning agents react with heat to loosen paint.
