Learning how to clean a double oven means learning how to treat two very different cavities. The top is usually a smaller grill oven that scorches everything within centimetres of the element, and the bottom is a full-size fan oven that catches every drip from a roast. This guide covers both cavities, the shared door and the trims in between, whether you have a built-in double oven or an electric double oven that stands on its own.
Quick answer
To clean a double oven, treat the top and bottom cavities separately. Remove all shelves, soak them in warm soapy water, then apply a bicarbonate of soda paste to each cavity. Leave for thirty minutes, wipe out with an e-cloth, then rinse. The top usually needs less soak time; the bottom often needs a second pass on the floor.
Double oven vs single oven — why cleaning differs
In a double oven electric setup, the top cavity is small, hotter per centimetre because the grill sits close to the food, and mostly used for toasting, grilling and reheating. The bottom is the main oven, often fan-assisted, and gets a full week of roasts, tray bakes and pizzas. Because they share a control panel and, in many built in double oven models, a single outer casing, the trims and hinges between them collect grease from both cavities. Cleaning as two jobs, one for each cavity, keeps the results even and stops you working carbon from the bottom oven up onto the top grill element.
What you’ll need
- Rubber gloves
- Two mixing bowls (one for each cavity’s paste)
- Bicarbonate of soda
- White vinegar in a spray bottle
- Washing-up liquid — Ecover or Method work well
- Three or four e-cloths
- A soft-bristled brush for the grill element housing
- An old towel for the floor in front of the oven
Step-by-step: cleaning both cavities
- Isolate the oven at the wall switch. Let it cool completely if it has been used that day.
- Remove shelves and side rails from both cavities. Lay them on an old towel in the sink or bath and cover with warm soapy water.
- Mix a bicarbonate paste at three parts powder to one part water. Split into two bowls.
- Spread paste thinly across the top cavity walls, floor and grill panel. Avoid the exposed grill element directly.
- Repeat in the bottom cavity, paying attention to the floor and the back where the fan cover sits.
- Leave both cavities for thirty to forty minutes.
- Wipe out the top cavity first with a damp e-cloth, top down. Mist with vinegar to lift residue and buff dry.
- Wipe out the bottom cavity the same way. If the floor still feels tacky, apply a second thin paste and leave a further twenty minutes.
- Scrub the shelves in the sink, rinse and dry.
- Restore rails, then shelves, then power.

The shared door and trims
Most double ovens have a single tall door for the main cavity and a smaller door above. Wipe both inner glasses with a bicarbonate paste, working with a damp e-cloth in small circles. The metal trim between the two cavities is a magnet for splatter — a soft brush and warm soapy water lifts it without scratching the enamel. If the outer stainless-steel fascia is streaky, finish with an e-cloth and a drop of Method stainless-steel spray, always following the grain of the metal.
Common mistakes to avoid
Using strong sprays in the top cavity
The grill cavity is small and closes in on the fumes. Strong caustic sprays are much harder to rinse out here. Bicarbonate paste is a safer choice for the top oven.
Forgetting the grill pan handle
The plastic or bakelite handle on a grill pan is not dishwasher safe. Wash it by hand and dry it fully before storing.
Cleaning while warm
A warm cavity dries paste on before it can work. Always clean cold.

How often to clean a double oven
Because the two cavities are used differently, they need cleaning on different rhythms. Wipe the top cavity every fortnight after grilling — grease bakes on quickly there. Deep-clean the bottom cavity every eight to twelve weeks for a family that cooks daily. Both cavities benefit from a professional strip once a year, especially if the oven is built in and the shelves have never been dipped. Neglecting either cavity eventually transfers grease and smells to the other.
Conclusion
A double oven electric appliance is only as convenient as its cleanest cavity. Treat top and bottom as two separate jobs, keep bicarbonate paste as your default cleaner, and never spray strong products near the exposed grill element. If yours has not had a full strip in a year, book a professional oven cleaning in London and we will bring both cavities back to showroom condition.
