Quick answer: Remove the racks and soak them in hot, soapy water. Make a paste from bicarbonate of soda and water, spread it over the oven interior and glass door, and leave it for at least twenty minutes, longer for heavy grease. Wipe away with a damp cloth, then scrub the racks separately before rinsing everything and drying thoroughly.
Few kitchen jobs get put off as often as cleaning the oven, and few appliances make such a visible difference once the job is finally done. Whether you prefer a natural approach with store-cupboard ingredients or want to understand what your oven’s self-cleaning function actually does, this guide covers every part of the job from racks to glass doors.
What You Will Need
- Bicarbonate of soda
- White vinegar
- Washing-up liquid
- A soft cloth or sponge, plus a non-abrasive scrubber
- Rubber gloves
- A spray bottle
- An old towel to line the sink or bath for soaking racks
Avoid wire wool or other harsh scourers on glass or enamel surfaces, since these can leave fine scratches that weaken the surface over time.
Step 1: Remove the Racks and Loose Debris
Take out the oven racks, trays, and any other removable parts. Tip out or brush away any loose crumbs and debris from the base of the oven before you start applying any cleaning products, so you are not working around loose mess.
Step 2: Clean the Oven Interior With Baking Soda
- Mix bicarbonate of soda with a small amount of water to form a thick paste, roughly the consistency of toothpaste.
- Spread the paste generously over the interior walls, ceiling, and base of the oven, avoiding the heating elements themselves.
- Leave it to sit for at least twenty minutes. For an oven that has not been cleaned in a while, leaving it overnight gives the paste much longer to break down baked-on grease.
- Wipe away the paste with a damp cloth, using a non-abrasive scrubber on any stubborn patches.
- For particularly tough spots, spray a little white vinegar over the remaining paste residue. The fizzing reaction helps lift the last of the grime.
Step 3: Clean the Glass Door
- Apply a paste of baking soda and water to the glass, avoiding any rubber seals around the edge.
- Leave it for around twenty minutes.
- Wipe away with a damp cloth, then follow with a vinegar-based glass cleaner for a streak-free finish.
- If your oven allows it, check the manual for how to remove the glass panel for a deeper clean between the inner and outer layers, where grease often accumulates unseen.
Avoid caustic-based oven cleaners on glass, since these can damage the surface over time even if they work well on metal interiors.
Step 4: Clean the Racks and Trays
- Line a sink or bathtub with an old towel to prevent scratching, then fill with hot water.
- Add washing-up liquid, or for tougher grease, a biological washing powder or a dishwasher tablet.
- Submerge the racks and trays fully and leave to soak for several hours, or overnight for heavily soiled items.
- Scrub with a sponge or non-abrasive brush once the grease has loosened.
- Rinse thoroughly and dry before returning them to the oven.
Understanding Self-Cleaning Ovens
If your oven has a self-cleaning function, it is worth knowing which type you have before reaching for baking soda and a scrubbing brush.
Pyrolytic
Pyrolytic ovens heat to a very high temperature, burning off grease and food residue until it turns to ash, which you then wipe away once the oven has cooled. This is the most thorough self-cleaning method but uses more energy during the cycle.
Catalytic
Catalytic ovens have special panels lining the interior that absorb grease during normal cooking and break it down at regular oven temperatures, reducing how often a full manual clean is needed.
Steam Cleaning
Steam-clean ovens use a cycle with water to loosen grime, which is then wiped away by hand. This is gentler than pyrolytic cleaning but generally needs more manual effort afterwards.
Check your oven’s manual to confirm which type you have and follow the manufacturer’s instructions for the self-clean cycle, since the process differs between models.
Does Oven Type Affect Cleaning?
Gas ovens can trap grease in and around burners and igniters, which need a closer inspection alongside the main interior clean. Electric ovens are often more straightforward, though burnt-on food around heating elements can be stubborn. Enamel-coated interiors need gentler treatment, since strong acidic cleaners like neat vinegar can react poorly with some enamel finishes, so always check your manual if you are unsure.
How Often Should You Clean Your Oven?
A deep clean every few months keeps most ovens in good condition, with a quick wipe-down after particularly messy cooking sessions in between. Spills and heavy grease are much easier to remove while still fresh, so wiping up major spills as soon as the oven has cooled prevents a much bigger job later.
Professional Oven Cleaning
If the job feels too daunting, or the oven has not been cleaned in a very long time, professional oven cleaning services are widely available across the UK, typically starting from around £50 depending on whether you have a single or double oven, and whether the service also covers the hob and extractor hood.

Frequently Asked Questions
How do you clean an oven naturally?
A paste of bicarbonate of soda and water, left to sit for at least twenty minutes before wiping away, is the most widely used natural method. White vinegar sprayed over stubborn residue helps lift the last of the grime.
What is a self-cleaning oven and how does it work?
Self-cleaning ovens use one of three methods: pyrolytic, which burns residue to ash at very high heat, catalytic, which uses special panels that absorb grease during cooking, or steam cleaning, which loosens grime with a water-based cycle.
How do I clean oven racks without scrubbing?
Soaking them for several hours, or overnight, in hot water with washing-up liquid or biological washing powder loosens most grease so it wipes away with minimal scrubbing.
How much does professional oven cleaning cost?
Professional oven cleaning in the UK typically starts from around £50, with the exact price depending on whether it is a single or double oven and whether the hob or extractor is included.
Final Thoughts
A dirty oven is one of those jobs that feels bigger than it is once you actually get started. Bicarbonate of soda handles most of the work naturally, racks clean up easily with a long soak, and knowing whether your oven has a pyrolytic, catalytic, or steam self-clean function can save you a lot of scrubbing in future.
