An oven is four cleaning jobs in one box: the racks, the enamel interior, the door glass and the element surround. Doing them in the wrong order means carrying grease from one surface onto another, and using one product for all four is how aluminium racks get ruined.
Match the product to the surface
Clean the racks separately by soaking them, treat the enamel interior with a caustic or non-caustic oven cleaner and dwell time, do the door glass with a plastic scraper rather than a blade, and keep caustic away from aluminium racks and painted panels. Rinse twice, because residue browns at the next bake.

Step 1: racks out and soaking
Racks are the dirtiest part and the easiest to damage. Lift them out, put them in a sink or a tub with hot water and a heavy-duty degreaser, and leave them while you do the interior. Twenty minutes is usually enough; overnight for baked-on carbon.
If the racks are chrome-plated steel, a nylon scourer is fine. If they are aluminium, do not use caustic and do not use steel wool — the finish will pit and discolour, and no product restores it.
Step 2: the enamel interior
- Warm the oven to about 50 °C and switch it off. Warm surfaces let the cleaner work; hot surfaces flash it dry.
- Apply the cleaner to the sides, back and floor, keeping it off the element, the fan surround and the door seal.
- Leave it for the label dwell time — ten minutes minimum, twenty for heavy soil.
- Wipe out with a damp cloth, working top down so the run-off does not re-soil what you have cleaned.
- Rinse twice. Caustic residue left in the oven browns again at the next bake.

Step 3: the element and the fan surround
These are the parts most people damage. The element is fragile and caustic overnight soaks will shorten its life; wipe it with a cloth dampened with detergent solution and no more. On a fan oven, grease builds on the fan cover and the rear panel, and that is where the smell comes from at the next bake — remove the cover if the manual shows how, soak it, and clean behind it.
Step 4: the door glass
The inner glass is the same job as any oven door: cleaner, dwell time, wipe, then a plastic scraper for what is left. A metal blade scratches oven glass permanently, and scratched glass traps carbon and looks dirty even when it is clean. The stain between the door panes cannot be reached from the oven side; it needs the inner pane removed. Our guide to cleaning an oven glass door covers that job in detail.
Self-cleaning and pyrolytic ovens
A pyrolytic cycle burns residue to ash at around 450 °C; when it finishes, wipe the ash out with a damp cloth. Two warnings: do not use chemical cleaner before a pyrolytic cycle, because the residue bakes into the enamel, and on some machines the racks cannot go through it. Steam-clean functions are gentler and do less — treat them as a pre-soak, not a clean.
Questions we get asked most
- What is the best way to clean the inside of an oven?
- Warm it, apply a caustic or non-caustic cleaner, leave it for the label dwell time, wipe top-down, then rinse twice. Racks come out and soak separately, and the element and fan cover are wiped rather than soaked.
- Can you clean an oven with a dishwasher tablet?
- People do it because tablets contain alkaline detergent and enzymes, and it works on light grease in a bowl of hot water. It is weaker than a purpose-made oven cleaner and leaves residue that needs rinsing twice.
- How do I get brown stains off my glass oven door?
- Cleaner, dwell time, damp wipe, then a plastic scraper. Stains between the door panes need the inner pane removed — no product reaches them from inside the oven.
- Can I clean my oven myself?
- Yes, provided you match the product to the surface and give it dwell time. The jobs worth paying for are heavy carbon in a commercial range and anything that needs the oven disassembled.
- How often should an oven be cleaned?
- Domestically every few months or when it smells at the next bake. In a commercial kitchen it is a scheduled task, usually daily for the range and weekly for a deeper clean, and recorded.
