A:Answer Hi Teal - Thanks for reaching out to us! We recommend to wash the racks with warm, soapy water. The standard oven racks / shelves are chrome plated and can be cleaned in a self-cleaning oven; however, it is not recommended since they may discolor and lose some of their luster. They typically discolor to a deep gray after self-cleaning. To keep the luster, the racks should cleaned with soap and water rather than cleaned in the oven's self-cleaning cycle. Commercial oven cleaner may used for the racks, but some cleaners cause discoloration. Be sure to do a small test area to check the results, and rinse the racks thoroughly after cleaning. You can also view cleaning recommendations for the various parts of your range in the Owner's Manual at the following link: https://products.geappliances.com/MarketingObjectRetrieval/Dispatcher?RequestType=PDF&Name=49-80805-1.PDF - Thanks for choosing GE!
