Avoid unnecessary spatters by covering dishes, using wax paper or paper towels. If the oven does not have a removable glass shelf, a plate or paper towel placed under the food (such as baked potatoes) keeps it cleaner. Wipe up spills after cooking. Wash regularly with mild detergent and water. Rinse and wipe dry with a paper towel or clean cloth. Especially clean around edge of door and door opening, to prevent soil buildup which would prevent door closing tightly. If spots seem dried on, boil water in a glass cup a few minutes; steam will help loosen soil. Leave in oven 5 minutes. Then wipe dry. If odors, either clean the interior with a solution of 1 tablespoon baking soda to 1 cup warm water, rinse and dry. Or mix 1 part lemon juice to 3 parts water in a large glass cup and boil 3-5 minutes. Let cool. Then remove water and wipe dry. Never use abrasive pads or powders on oven. click here
