How to Clean an Oven: Door Glass, Racks and Burnt-On Grease

How to clean an oven comes down to one question: what are the walls made of? A smooth enamel oven can take a cleaner marked safe for enamel, or a bicarbonate paste. A catalytic oven has rough liners that sprays will ruin. A pyrolytic oven burns its own grease to ash, and usually needs only a damp cloth afterwards.

Whichever you have, the order is the same. Switch off and let it cool. Take out the racks and everything else that moves. Clean the racks away from the oven, because they need a long soak. Clean the inside according to its type. Do the door glass last, with hot soapy water and a soft cloth. Then rinse everything well, because residue left in the cavity ends up near your food.

If you only have an hour, do the door glass, the racks you can reach and the floor of the oven, since those are what people see. If you are moving out, give yourself two days: one to soak, one to finish. Our end of tenancy cleaning checklist shows where the oven sits in the rest of the job.

Open the door and run a finger along the side wall of a cold oven. Enamel feels smooth and looks glossy. A catalytic liner feels rough, like fine sandpaper, as Which? describes it. If the controls include a cleaning programme, or the manual mentions pyrolysis, you probably have a pyrolytic oven, and Hotpoint says dial models show a square with dots as the symbol. A steam or hydrolytic function is a fourth type, which needs water in the base or a tin, or in a reservoir on some models.

Do not guess if you are unsure, particularly in a rented flat where the appliance is not yours. The model number is usually on a plate inside the door frame, and most makers publish manuals online. Beko's advice is the same: check the manual or download it if you cannot tell. That five-minute check matters more than any product you buy.

Many ovens combine types. Which? notes that some catalytic ovens line the sides, roof and back, while others line only the back wall, so the plain surfaces still need cleaning by hand. AEG tells owners to clean non-catalytic surfaces in the usual way before running a catalytic cycle.

Manufacturers are clearer about what to avoid than about what to use, and the warnings overlap. Bosch tells owners to avoid chlorine-based and abrasive cleaners, abrasive cloths and harsh chemicals that can damage the appliance. It also warns that using special cleaners in a hot oven can be dangerous and can damage the enamel. Which? adds that many products should not touch door seals, heating elements, aluminium or non-stick surfaces.

Catalytic liners need the strictest care. AEG says never to apply detergent to them, and not to use oven sprays, abrasive cleaners or soap. Beko says not to clean them at all, and to run the oven at 240°C for an hour. Hoover agrees that oven cleaners must not be used, but says hot soapy water is fine for wiping the liners. So the makers disagree on soap. Our advice is to use water and soap only if your own manual allows it, and otherwise leave the liners alone. AEG also says spots or discolouration may remain and do not affect the oven, so do not try to scrub them out.

The parts you should keep dry, or at least keep cleaner away from, are the same on almost every oven. Which? says to avoid the fan and, on gas ovens, the gas supply elements and pilot light. Whitegoods Help, a UK appliance repair site, adds the thermometer probe and warns that harsh chemicals can make rubber seals crack or perish. Wipe seals with a damp cloth and a little washing-up liquid. Wipe around the fan cover, and leave the blade where it is.

Treat a strong oven cleaner as a corrosive chemical, because that is often what it is. A study of calls to the UK National Poisons Information Service between 2009 and 2015 covered 780 patients, and about 96% of the products involved contained sodium hydroxide, potassium hydroxide or both. Most effects were minor, and about 4% of cases were moderate or severe, but burns occurred in 44% of skin exposures, mostly on the hands and arms. Sodium hydroxide is also called caustic soda, and UKHSA says stronger solutions can cause pain, burns and ulcers on skin, and burns to the eyes.

Read the label before you open the box, including the small print on the back. The Health and Safety Executive says labels and safety data sheets show whether a product can harm skin, and lists a corrosion symbol among the GB hazard pictograms. If you see that symbol, follow the instructions exactly. HSE's COSHH rules bind employers rather than householders, but the logic carries over to your kitchen: avoid the substance if you can, swap it for something milder, and keep your skin away from it.

Rinsing matters as much as scrubbing. The same poisons study recorded 182 people who ate food they believed had been contaminated by oven cleaner. Whitegoods Help suggests running the empty oven at about 180°C for 15 to 20 minutes before you next cook.

The NHS says to call 999 if a chemical gets on someone's skin or in their eyes, because these burns need to be checked and treated in hospital. Wear gloves if you are helping someone else. Remove clothing with the chemical on it, taking care not to spread it. Rinse the area with cool or lukewarm running water for about an hour, and do not put creams or anything else on the burn.

Sources give different rinsing times. UKHSA's advice on sodium hydroxide says at least 10 to 15 minutes for skin and eyes, with contact lenses removed, then medical advice. The NHS says about one hour. Follow the NHS and keep rinsing until help tells you to stop.

If fumes make you cough or your chest feels tight, move into fresh air and get medical advice, because UKHSA says serious effects on the lungs can take up to 36 hours to develop. If someone swallows oven cleaner, get medical advice straight away and take the container with you, so whoever treats them can see what it was.

This is the full method for an enamel oven, or for the plain surfaces of a catalytic one. For a pyrolytic oven, skip to the short version under the list. Allow an evening to apply the cleaner and a morning to finish it, or use a fast product and a free afternoon. The chart below shows why the timings vary so much.

Pyrolytic cleaning is close to hands-free, but it is not nothing. Sources quote slightly different heat: Hotpoint says 470°C, Bosch 485°C and Which? roughly 500°C. Cycle times differ too, from one to four hours in the Which? self-cleaning guide, two to four hours from Hotpoint, and three to five hours in Which?'s oven cleaner guide. Treat it as a job for half a day when you are at home.

First, take out everything. Hotpoint says always to remove shelves, trays and side supports, because they cannot withstand the heat, and Bosch warns that telescopic racks can get stuck. Wipe up any large spills, then close the door and start the cycle. The door locks automatically and must not be forced. The glass can get hot, so keep hands off it. Which? says the smoke can smell unpleasant, so run the cooker hood or open a window, and keep children and pets out of the kitchen. When it has cooled, wipe out the ash with a damp cloth.

A cycle costs about £1.33 at the October to December 2026 energy price cap, according to Which?, against 31p for a catalytic clean and 6p for a steam clean. Which? also notes the heat can wear elements and cloud the door glass over time. That is one more reason to run it as a deep clean, every 6 to 12 months as Bosch advises, and not as a weekly habit.

For a catalytic oven, take out accessories and removable shelf supports, clean the plain surfaces first, then run the programme. AEG says to use its dedicated programme if there is one, or set 250°C for an hour. Beko says 240°C for an hour. When the oven has cooled, wipe the floor with a soft cloth. Which? rates catalytic the least effective of the three types, says it works on grease and fat but not on sugary spills, and says liners wear out over time. If grime stays on a liner, the honest answer is that it may be time for a replacement liner, and not a stronger cleaner.

Baking soda and vinegar are worth trying on a lightly soiled enamel oven, and they are the gentlest option for someone who wants to avoid caustic products. They are not magic. Bicarbonate of soda is a mild abrasive and a weak alkali, and it works mainly by softening grease over a long time. Burnt carbon that has been through a hundred Sunday roasts usually needs something stronger, or a professional.

To clean an oven with baking soda, mix equal parts bicarbonate of soda and water into a paste. Rub it onto the greasy areas of a cold oven, keeping it off the elements, fan, seal and any catalytic liner. Which? says to leave it for at least an hour, longer for stubborn spots, and overnight for hard deposits. Then scrape it away with a plastic spatula and wipe with a damp cloth. The white film takes several rinses to clear, so allow for that.

The vinegar part is mostly theatre if you mix the two. A Which? scientist explains that bicarbonate is an alkali and vinegar an acid, so they neutralise each other, and the fizz is just carbon dioxide. Which? says they can work on ovens if used one after the other, not mixed beforehand. So use the paste, wipe it away, then spray a solution of one part white vinegar to three parts water to help lift the last of the film.

One warning: do not use bicarbonate on the door glass. Which? says it can leave tiny scratches. And keep it away from high-shine finishes such as polished stainless steel and chrome.

The dishwasher tablet trick is popular online, and the honest result is mixed. Which? tested it and found tablets were most effective on the shelves, and less so on oven doors or walls. Which? also lists rubbing a tablet over the oven as a popular method it has compared with others, but its detailed findings sit behind a free account.

So use a tablet for what it does well. To clean racks with one, fill a bath or large tub with hot water, drop in a tablet, and submerge the racks for a few hours. Which? says to cushion them with towels or a mat, so they do not scratch the bath. Wear rubber gloves when you take them out, because dishwasher tablets are strong detergents, and rinse the racks thoroughly.

We would not rub a wet tablet over the inside of an oven. A tablet breaks up as it gets wet, the residue then has to be rinsed out of the whole cavity, and Which?'s result suggests the effort is poorly repaid. We would also not put a tablet in a hot oven, as some videos do. None of the makers' pages we read recommends either, and heating an unknown cleaning product in a closed box near your food is an easy thing to skip.

Oven racks are the part that gets left until last and takes longest, so start them first. Which? says they are usually easy to remove and soak. The right method depends on how bad they are. Light grease comes off in hot soapy water, as Bosch advises: soak for several hours, then scrub, rinse and dry. Bosch's page also suggests a bath of dish soap and dryer sheets, though we cannot confirm the sheets add anything.

For heavy, baked-on grease, a bag kit works well. The racks go into a large resealable bag with a specialist fluid, and Which? says to leave them for at least four hours, then rinse off the residue. Which? warns that this fluid is very harsh and corrosive, so wear full protection, seal the bag properly and keep it in a tub on the floor or outside, away from children and pets. Check first that your racks are not aluminium or non-stick, because Which? says many cleaners must not touch either.

Be careful with the bath. Which? says to use only gentle, natural products in an enamel bath, because harsh ones can corrode it. That rule matters more in a rented flat, where a marked bath is one more thing to explain at check-out. Our recommendation is to use a plastic tub, a washing-up bowl or a strong bin bag for anything stronger than washing-up liquid, and to keep caustic products out of the bath altogether.

Oven door glass is the first thing an inspector or a guest sees, and also the easiest part to damage. Start gently. With the oven cold, lay a towel on the floor below the door, wipe the glass with hot soapy water and a sponge or microfibre cloth, and let it soak for a few minutes under a wet cloth. Wipe again. Which? and Bosch both give warm or hot soapy water as a starting point, and most light grease will shift.

Next, for baked-on marks, use a product your oven maker allows. Bosch points to a degreaser, sprayed on, left for 5 to 10 minutes and wiped off with a damp cloth. Neff suggests leaving its cleaner on for at least 15 minutes for stubborn grease. Which? says some chemical cleaners are labelled safe for glass, but that caustic-based ones will damage it, so read the label before you spray.

On finishing products, makers disagree. Bosch says not to use a glass scraper or glass cleaner on the door. Neff tells owners of its Slide&Hide ovens to clean the glass with glass cleaner and a soft cloth. Which? suggests a vinegar-based glass cleaner for a streak-free finish. So we recommend soapy water first on every oven, and a dry microfibre cloth to finish. Use glass cleaner only if your manual allows it.

Whatever you use, keep out wire wool, harsh scourers and scrapers. Which? says they can scratch the glass and weaken it. Bosch adds that you should not press hard on the door while cleaning. Whitegoods Help says cracked glass is a safety issue, and that it should be replaced before you use the oven again. If the marks are inside the glass, no amount of wiping will help; they are between the panes, and that is the next section.

If streaks stay after you have cleaned both faces, the grease is between the layers of glass. Which? says that if the panels can be removed, you can soak them, but to check the manual first. Bosch says the same. Do not try to force a door apart if your manual has no instructions for it. Whitegoods Help suggests asking an engineer in that case.

Doors differ, so the steps below are a typical outline taken from Neff's and Bosch's instructions, not a method for your model. Neff warns that some steps vary, and on its doors it describes pushing the hinge locks up with a screwdriver and turning the locks at the bottom of the door with a coin. Other makes differ. Bosch's method uses locking levers on the hinges and a cover at the top of the door that comes away to release the glass.

Get a second pair of hands, because oven doors are heavy and awkward to hold level. In a rented home, weigh it up: a broken door is a much bigger problem than a streak, and a landlord's appliance is not the place to learn. Our recommendation is to do this yourself only if the manual shows every step and you can read it with the door in front of you.

An oven clean that stops at the door can still look unfinished, so do the hob and the cooker hood on the same day. For a ceramic or induction hob, Bosch says to wait until the surface has cooled, apply a hob cleaner with a non-shedding cloth or kitchen paper, then wipe with a damp cloth and dry. Its maintenance pack includes a glass scraper for burnt-on spills on the ceramic glass, but this is for the hob glass only. Do not use it on the steel surround, and never on the oven door.

For a gas hob, lift off the pan supports and burner caps if your manual allows it, soak them in hot soapy water, and dry them fully before you put them back. Keep liquid out of the burner holes and the ignition points. Oven cleaner does not belong on a hob unless the label says so.

The extractor is where most kitchens are behind. Bosch says to switch off and unplug the hood, take out the metal grease filter, soak it in warm water with mild detergent for 10 to 15 minutes, brush it with something soft, rinse and leave it to air-dry. Do not use a hairdryer. Some filters can go in the bottom of a dishwasher, if the manual says so. Bosch's page on venting hobs says the metal filter should be cleaned every 30 operating hours or at least once a month. Carbon recirculating filters cannot be washed and need replacing.

Pull the cooker out if it is freestanding and you can do so safely. Do not move a gas cooker beyond what its hose allows. Grease behind a cooker is more than a cosmetic problem: as our guide to cockroaches in the UK explains, it can be food for them. For a kitchen that needs more than this, see our one-off cleaning services.

Clean little and often. Which? recommends a wipe at least once a month, and a clean-up of any spill once the oven has cooled, particularly after roasts or bubbling casseroles. Whitegoods Help suggests a full clean every three months for average use. Those two fit together: a monthly wipe, and a proper clean each quarter. If you cook most days, bring that forward. If you live alone and use the air fryer, every six months may do.

A burning smell when you preheat is the signal. Which? says it usually means an old spill is burning off, so wipe it when the oven is cool, before it bakes on harder. Beko goes further and says that wiping an enamel oven with a damp cloth while it is still warm is the most effective method of all, though it needs care. Wait until it is warm and not hot, and use an oven glove.

Prevention saves the most effort. Which? suggests covering messy dishes with a lid or foil when slow-cooking, and putting a baking tray under anything that may bubble over. Pyrolytic owners should stick to Bosch's 6 to 12 months, and catalytic owners should follow the manual. Which? says the liners work at about 200°C or above, so an oven only ever used on low settings is unlikely to be doing much for itself.

TDS names the oven as a high-use area to check at move-in. An article for the National Residential Landlords Association by TDS's Sandy Bastin says cleaning is the most common type of dispute, and mydeposits says the same of deposit claims. The rule is simple: the Tenancy Deposit Scheme says a tenant should return the property cleaned to the same standard as at the start. It also says cleanliness is not covered by fair wear and tear, so an old oven can be aged but should still be clean.

Your starting point is the check-in report. If it says the oven was professionally cleaned, TDS says you should clean to that standard. If the oven was already greasy when you arrived but the report says clean, mydeposits says to tell your landlord or agent in writing straight away. The TDS articles are from 2018 and 2019 and reflect their authors' views, but the principle is still how disputes are framed. TDS also notes that adjudicators avoid betterment, meaning a tenant should not be made to leave things better than they found them.

Do not leave it until the final day. Start the racks two days before your check-out, finish the cavity the day after, and take dated photos before you hand back the keys. TDS says a written description matters most, but that photos can help with the inside of an oven. Keep any receipt, whether it is for a cleaner or a product. For the rest of the process, read our guides to tenancy deposit cleaning deductions, how much end of tenancy cleaning costs and moving house. The carpets will need attention too, so see how to clean carpet.

Do it yourself if the oven is lightly soiled, you know its type, and you have time. A product costs little: Which? says one of its Best Buy cleaners is under £2. Pay for a clean if the carbon is thick, if you have no safe way to use caustic products, if the door needs to come apart and you do not trust yourself to do it, or if the time is worth more to you than the fee. Which? puts a professional clean at from about £50 for a single oven and £70 for a double, and notes that this can be cheaper than buying a self-cleaning oven if you rarely need one.

Range cookers are their own case. They have more cavities and parts, so we quote them separately from a standard oven. See our range cooker cleaning and Aga cleaning pages before you start on one, because a heat-storage cooker has its own rules. A barbecue has a separate page too: BBQ cleaning.

Our oven cleaning service starts from £45 per visit, for built-in or freestanding appliances. It covers a full interior degrease, with racks and trays soaked separately, and a hob and extractor filter clean. Let the oven cool, and tell us the model or range type if you know it, so we can check the right method for your oven. Appliance size, condition, removable parts and access affect the quote, and the price is confirmed in writing before you book. A wider job can come under appliance cleaning.

If you are moving out, it usually makes sense to book the whole property. End of tenancy cleaning is a flat rate by size: £130 for a studio, £200 for one bedroom, £230 for two, £300 for three and £350 for four. Mention the oven when you enquire, so its scope and any extra cost are in your written quote. An oven or range degrease add-on is £25. End of tenancy cleans carry our 48-hour re-clean guarantee: if your letting agent or landlord raises a cleaning issue within 48 hours, we return and re-clean those areas at no charge. See our prices page for the rest.

We are based on Clements Road in Ilford, cover London, and carry public liability insurance. Our phone lines are open Monday to Saturday, 8am to 8pm. If your mattress needs attention before you hand back the keys, we have a guide on how to clean a mattress as well as a mattress cleaning service.
