Hi, Granpop4! Self-clean is a great feature and is available on several of our models. Since this model does not have it, it is safe to use oven cleaners. Gentle scouring with a soapy non-abrasive scouring pad will remove most spots. Rinse with a 1:1 solution of clear water and ammonia. If necessary, cover difficult spots with an ammonia-soaked paper towel for 30 to 40 minutes. Rinse with clean water and a damp cloth, and then scrub with a soap-filled non-abrasive scouring pad. Rinse and wipe dry with a clean cloth. Do not allow food spills with a high sugar or acid content (milk, tomatoes, sauerkraut, fruit juices or pie filling) to remain on the surface; they may cause a dull spot even after cleaning. The oven interior is porcelain coated and is safe to clean using oven cleaners. After cleaning, remove any oven cleaner or the porcelain may become damaged during future heating. Do not spray oven cleaner on any electrical controls or switches. Do not spray or allow oven cleaner to build up on the oven temperature sensing bulb. Do not spray cleaner on the oven door trim, door gasket, plastic drawer glides, handles or any exterior surfaces of the range. Clean any soils from the oven frame, the door liner outside the oven door gasket and the small area at the front center of the oven bottom. Clean with hot, soapy water, and rinse using clean water and a cloth. ~ Brandi
