Nobody opens the oven door on a Sunday afternoon and feels good about what they see. The baked-on grease around the edges, the mystery black patch on the bottom, the smell that hits you the second you turn the heat up. It builds up quietly for months, and then one day you notice it all at once.
The good news is you don't need a cupboard full of harsh sprays to fix it. Here's how to clean an oven properly using bicarb, vinegar and a bit of patience, so it's spotless and safe to cook in again without the fumes.
What you'll need
- Half a cup of bicarbonate of soda (bicarb)
- White vinegar in a spray bottle
- Warm water
- A bowl for mixing
- Dishwashing liquid
- A non-scratch scourer or an old toothbrush
- Rubber gloves
- A few old towels or rags
- A butter knife or plastic scraper (optional, for stubborn bits)
Nothing here needs to come from the cleaning aisle at a premium price. Most of it's already in the pantry.
How to clean an oven: step by step
Step 1: Clear it out
Pull the racks and any trays out first. Set them aside, you'll deal with them separately in step 5. Give the inside a quick once-over with a dry cloth to sweep out loose crumbs and bits of debris. It makes a real difference to how far the paste can actually reach.
Step 2: Mix the paste
Combine half a cup of bicarb with a few tablespoons of warm water in a bowl. You're after a thick, spreadable paste, roughly the texture of toothpaste. Add water a little at a time; it's easy to go too thin.
Step 3: Coat the interior and leave it
Using gloves, spread the paste over the base, sides, back and inside of the door, avoiding any exposed heating elements. Get it into the grimiest patches especially. Leave it for at least 12 hours, or overnight if you can. This is the step people rush, and it's the one doing most of the work.
The paste will turn a light brownish colour as it lifts the grease and grime. That's exactly what's supposed to happen.
Step 4: Wipe it out and spray with vinegar
Using a damp cloth, wipe out as much of the dried paste as you can. Expect a bit of a workout on the thicker patches. Once most of it's gone, spray the whole interior lightly with white vinegar. It'll fizz slightly on contact with any leftover bicarb, which helps lift the last of the residue.
Wipe it all down again with a clean, damp cloth until the surfaces come up clear. Two or three passes usually does it.
Step 5: Clean the racks separately
While the paste is working its magic inside the oven, soak the racks in a bath or a large sink of hot water with a squeeze of dishwashing liquid. Half an hour of soaking loosens most of the baked-on residue, and a non-scratch scourer handles the rest. Rinse and dry before putting them back in.
For stubborn, baked-on patches
Some spots don't budge on the first go, particularly the bottom panel under a heavily used grill. For those, apply a slightly thicker layer of paste directly to the patch, cover it with a damp cloth so it stays moist, and leave it a further few hours before scraping gently with a plastic scraper or the flat edge of a butter knife. Never use a metal scourer or anything abrasive on the enamel, it'll scratch the surface and make future buildup stick even more easily.
Don't forget the glass door
The inside of the oven door collects just as much grime as the cavity, and it's usually the most visible bit. Spread a thin layer of the bicarb paste over the glass, leave it for 20 to 30 minutes, then wipe clean and finish with a vinegar spray for a streak-free result. If your door has a removable inner panel, check the manual first, it's often far easier to clean once it's out.
And you're done. A clean oven doesn't just look better, it heats more evenly and stops burning off old grease every time you roast a chook.
When it needs more than a weekend job
This method handles the buildup that happens over weeks and months of regular cooking. If it's been years since the oven last saw a proper clean, or the grime has worked its way into corners and seals you can't reach, it might be worth calling in a hand. Our house cleaning service covers ovens and the rest of the kitchen as part of a broader clean, with fully insured, police-checked cleaners and a satisfaction guarantee if anything's not quite right.
