Kitchen ovens walls will always have splattering of the food being cooked and the external cover too gathers grime from the kitchen. There is no alternative really to cleaning up the kitchen oven regularly after use. This will ensure that the grease comes off much faster than dried up and layered grease. Products like ammonia in a glass dish left overnight in the oven helps remove grime. It is also worthwhile to try cleaning the grease with lemon and a mild detergent. For stubborn stains, the kitchen oven manual can be checked to confirm the kind of abrasive that can be used. The external oven cabinet can be cleaned regularly with a damp cloth and the wiped clean with a dry cotton or linen cloth. Any stains or food grease needs to be scrubbed off with a mild sponge damped with soap. It is necessary to leave the surface dry at all times.
