Avoid unnecessary spatters by covering dishes, using wax paper or paper towels when a looser cover is desired. Use an appropriate cover for the cooking process. If oven does not have a removable glass shelf, a plate or paper towel under food cooked directly on oven floor (such as baked potatoes) keeps it cleaner.

Wipe up spills at once. Wash regularly with mild detergent and water and rinse and wipe dry with 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 should 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. Follow manual directions for care. Microwave combination ovens (with convection or conventional heat) may have spills cook on from heat present. Follow manual directions for cleaning.
