Always try the least abrasive method depending on the amount of discoloration. Degreasers, powdered cleaners and cleaning pads may all be used. When using pads, please take care to use minimum pressure and go with the grain of the stainless steel. For stubborn stains, you may use oven cleaners making sure to follow the instructions on the product for use on stainless steel. In most cases this means protecting the burner heads when applying the product to the stained area, and allowing it to stand for the recommended time. When finished, please be certain to rinse well to remove any remaining residue.
