How to clean an oven

Inspired by Good Housekeeping UK. This guide draws on the "Cleaning Your Oven Can Be QUICK & EASY" video from Good Housekeeping UK, which tests products and methods on real ovens and shows which approaches actually shift the baked-on mess. Good Housekeeping is one of the most trusted household names in the UK for exactly this kind of thing.

1. Gather what you need

You will need a dedicated oven cleaner (spray or gel), rubber or nitrile gloves, a large bin bag or old towels for the shelves to soak in, a scraper or wooden spatula, a non-scratch scour pad, and some dry cloth or kitchen paper for wiping down at the end.

A bowl of warm soapy water and a few old cloths will deal with the lighter parts of the interior. For heavy carbonised build-up, a proper oven cleaner gel is more effective than any amount of scrubbing with washing-up liquid.

2. Remove the shelves and soak them

Slide out all the wire shelves and any enamel shelf guides. Put them straight into a large bin bag with a generous spray of oven cleaner gel, seal the bag, and leave them outside or in a utility room to soak while you work on the interior. A few hours is ideal; overnight is better for really gunked-up shelves.

To be fair, you can also use a bath of hot water with biological washing powder — leave them for several hours and the grease lifts off surprisingly well without harsh chemicals.

3. Apply cleaner to the oven interior

With the oven cold, spray or apply gel oven cleaner to the base, sides, top, and back of the cavity. Avoid the heating elements in an electric oven and the gas burner assembly in a gas oven. Wear gloves — oven cleaners are alkaline and caustic.

Follow the dwell time on the product — typically 30 minutes to a few hours. Longer is better for heavy soiling. Some people warm the oven very slightly first (about 50°C, then off) to open the grease; this helps the cleaner penetrate more quickly.

4. Tackle the door glass

Smear a thick layer of cleaner onto the inside of the door glass and leave it to work. Some oven doors can be removed entirely — check your model's manual. A detached door lying flat lets you really press into the glass without it all running down.

Once the cleaner has had time to work, scrape off the softened carbon with a plastic scraper held at a shallow angle. Follow up with a damp cloth and repeat if any stubborn patches remain.

5. Wipe out the cavity

Using a damp cloth or non-scratch pad, wipe the interior surfaces in sections. The softened grease and carbon should come away with moderate pressure. Rinse the cloth frequently in clean water so you are not just spreading dissolved grease around.

Several passes with a clean damp cloth are needed at the end to remove all the cleaner residue. Leftover oven cleaner burns the next time the oven heats up and produces unpleasant fumes — take the time to rinse it properly.

6. Clean the shelves and refit

Take the shelves out of the bin bag and rinse them with hot water. Most of the grease should wipe or scrub off easily after soaking. A non-scratch pad deals with anything still stuck. Dry them off before refitting — wet shelves left in an oven can mark the enamel.

Slide everything back, run the oven at 200°C for about 15 minutes to burn off any last traces of moisture or cleaner, then leave the door ajar to air out before cooking again.

7. Keep on top of it going forward

A quick wipe of the base and door after cooking while the oven is still warm (but not hot) takes two minutes and stops the build-up forming in the first place. Line the base with foil or a reusable oven liner to catch spills — just make sure it does not cover any vents.

When to call a handyman

Oven cleaning is mostly a DIY job, but call Richard if the oven itself needs a repair — a broken door seal, a faulty element, or hinges that are failing. A damaged door seal in particular affects cooking efficiency significantly and is worth sorting out.
