Cooking causes 90 percent of kitchen fires, and the first ignited material is usually built-up grease and oil. A quick biannual cleaning (at minimum) will extend you oven’s useful life, improve cooking time and ensure that the next time someone asks, “What’s that smell?” the answer is “grandpa” not your oven.
Check the gasket on the door and make sure that it seals the door to the oven. A bad gasket allows heat to leak out of the oven and skews cook times.
Check the oven light. If it’s out, simply remove the bulb and replace it with a new one from your local home improvement store.
Make a habit of removing soils immediately using hot soapy water and a scouring pad.
For heavier soil, allow a dish of ammonia to sit in the oven overnight with the door closed. Then, use hot, soapy water and a scouring pad to remove the soil. Rinse well with water and a clean cloth.
If you want to use an oven cleaner, please note: Follow the manufacturer’s instructions. Do not spray on electrical controls or switches. Do not allow a film to build up on any temperature-sensing bulb. Do not spray on door trim or the gasket, or on any exterior surfaces.
