Oven door glass comes clean with a paste of bicarbonate of soda and water, spread over the inside pane of a cold oven, left to soften the grease, then wiped off with a soft sponge and rinsed. The outside pane needs only warm water and washing-up liquid. The brown streaks you can’t reach are between the panes, and on many doors the inner glass lifts out so you can wash each pane on its own.
Interest peaks in December. Over the last five years, UK Google searches for cleaning oven glass have run highest in December, at almost twice the July level (Google Trends). The oven is also the first thing an inventory clerk opens at a check-out, so the same door matters if you are moving out after the new year.
An oven door has two, three or four panes
Beko’s oven guide says a door can have two, three or four pieces of glass, depending on the model. Each pane collects a different kind of dirt and wants a different clean.
| Pane | What builds up on it | How to clean it |
|---|---|---|
| Outer pane, facing the kitchen | Fingerprints, splashes from the hob | Warm water and washing-up liquid on a microfibre cloth, then dry it |
| Inner pane, facing the food | Baked-on grease and spatter | Bicarbonate paste and a soft sponge, on a cold oven |
| The panes in between | Brown streaks and drips that got in through the door vents | Only reachable by taking the door apart, on doors designed for it |
Cleaning the inside pane
- Let the oven go completely cold. Paste on warm glass dries in streaks, and warm glass can burn.
- Mix bicarbonate of soda and water into a thick paste. Which? suggests equal parts for oven grease; Housekeep uses three tablespoons of bicarbonate to one of water.
- Spread it over the glass and keep it off the rubber door seal.
- Leave it. Twenty to thirty minutes shifts a light film; heavy, dark grease wants a few hours.
- Wipe it off with a soft, damp sponge. No scourer, no wire wool and no blade.
- Rinse twice with clean water and buff the glass dry. Bicarbonate left on the glass dries to a white haze.
If you like vinegar for the final wipe, use it after the paste, never in the same bowl. Which? explains that bicarbonate of soda and vinegar neutralise each other when they are mixed, and the fizz is just carbon dioxide.
Shop-bought oven cleaner can go on the inside pane if its label says it suits glass and your type of oven. Keep it off the door seal and, on an oven with catalytic liners, off those panels: Beko says catalytic liners clean themselves once the oven reaches 200°C and don’t need cleaning. Never use it alongside another cleaning product.
Getting between the panes
Grease, crumbs and cooking liquid get into the gap through the vents in the door (Hunker points to the vents along the top). Heat then bakes them onto the inner faces of the glass, where no sponge can reach while the door is in one piece. That film is why an oven can still look dirty after a whole afternoon of scrubbing the inside pane.
Many doors are designed to come apart for exactly this. Bosch’s first instruction is to check in the manual that your model’s door can be removed. If it can:
- Lay towels on a flat surface so the glass can’t get scratched.
- If your manual says to take the door off first, open it fully, open the locking levers on the hinges and keep your fingers away from them, then lift the door off the way the manual shows.
- Take off the cover or trim along the top of the door. On some doors it lifts away; on others there is a screw at each side first.
- Photograph each pane in place, then lift them out one at a time.
- Wash each pane in warm water and washing-up liquid, using the paste above on any baked-on spots, and dry every pane completely.
- Put them back in the order they came out. Beko’s instruction for its doors is that the shiny side of the last pane faces towards the oven. Refit the trim.
If you leave the door on the oven, hold it while you work. Ransomspares’ Hotpoint guide warns that the door may begin to close once the inner glass is out, because it is suddenly lighter.
Some doors aren’t built to come apart. Housekeep notes that some older ovens, range cookers and Agas have fixed or riveted panels that only a specialist can open. On those, a damp microfibre cloth fixed round a thin ruler or a straightened coat hanger and slid in through the vent will lift some of the film, though it won’t leave the glass clear.
Self-cleaning ovens still need the door done
A pyrolytic cycle heats the empty oven to a very high temperature (480°C on Beko’s pyrolytic models) and locks the door until it has finished, turning residue inside the oven to dust. The film between the panes sits inside the door, out of the cavity the cycle cleans, so it needs the glass taking out like any other oven. Our kitchen appliance cleaning guide explains what enamel, catalytic and pyrolytic linings can each take.
Oven door glass can shatter without warning
Oven doors use tempered glass, which copes with heat and knocks far better than ordinary glass and is still brittle. Which? found that doors can shatter on their own, sometimes because of tiny flaws from manufacture such as nickel sulphide, which can expand years later, and sometimes after a knock in transit. The part you control is scratching. Which? warns that any kind of scourer can put tiny scratches in the glass that leave it vulnerable to shattering, so use a soft sponge and give the paste longer to work. If a pane is chipped, get an engineer to look at it before the oven goes back on.
Booking an oven clean before Christmas
Our oven clean takes out the racks, trays and other removable parts to soak, along with the inner door glass where the door design allows. The cavity and every pane are cleaned by hand in your kitchen, and most ovens are ready to cook with the same evening. A single oven is £77, a double £110, a single wide oven £114 and a 90cm range cooker £143. Where there’s no free parking, we add just what parking costs us.
Moving out? With an end of tenancy clean the oven is an add-on at £31 per oven, or £62 for a double or a range cooker, and the invoice is useful evidence if the oven is questioned at check-out. For a check-out date, book a week or more ahead. Our guide to what London inventory clerks check covers the rest of the kitchen.
Questions we get asked
Can you clean between oven glass without taking the door apart?
Partly. A damp microfibre cloth wrapped round a thin ruler or a straightened coat hanger, slid in through the vent at the top of the door, lifts loose grease and dust. It won’t give a clear finish. For that, the inner glass has to come out, which many doors allow; the manual for your model says whether yours does and how.
Why is there grease between the panes of my oven door?
Cooking vapour, splashes and crumbs get in through the vents in the door and settle on the inside faces of the glass. Every time the oven heats up, the film bakes on a little harder and turns brown. On doors where the inner glass comes out, warm water and washing-up liquid shift it once the panes are apart.
Can I use oven cleaner on the door glass?
On the inside pane, usually, if the label says it suits glass and your oven. Bosch recommends its own degreaser, sprayed on and left for five to ten minutes, then wiped off with a damp cloth. Follow the label, keep the product off the rubber seal and any catalytic liners, and never mix it with another cleaner.
Does a pyrolytic clean do the door glass?
It cleans the inside of the oven, but the gap between the door panes is inside the door, so the cycle doesn’t reach it. That film still needs the inner glass taken out and washed. Take the shelves and accessories out before any pyrolytic cycle, as Beko’s guide instructs.
