How to Clean an Oven Like a Professional (Step-by-Step)
That blackened, crusty mess inside your oven didn’t appear overnight. And honestly? It won’t disappear with a quick wipe either. But don’t worry-we’ve got you covered.
We clean ovens daily, often ones that haven’t been touched in years. Here’s exactly how we tackle even the worst cases, broken down so anyone can follow along.
Why Ovens Get So Bad
Every time you roast, bake, or grill, fat splatters and food particles escape. High heat bakes these onto surfaces almost instantly. Layer after layer builds up over weeks and months.
That brown coating isn’t just unsightly. It affects how your oven heats, can produce smoke, and might even trigger smoke alarms during cooking. Some of it becomes genuinely difficult to shift.
The Smell Problem
That burning smell when you preheat? It’s old grease and food residue being reheated over and over. Beyond being unpleasant, it can taint the flavour of what you’re cooking. A clean oven actually makes food taste better.
Most people put off oven cleaning because it seems like a massive job. And fair enough-it can take hours if you don’t know the right approach. But with proper technique, even neglected ovens come up surprisingly well.
What You’ll Need
Before diving in, gather everything. Nothing’s worse than stopping mid-clean to hunt for supplies. Here’s what professionals actually use-no fancy equipment required.
You probably own most of these already. If not, any supermarket carries them for a few pounds total.
Essential Supplies
Heavy-duty oven cleaner (spray foam works best for vertical surfaces). Bicarbonate of soda for a natural alternative or stubborn spots. White vinegar in a spray bottle. Rubber gloves-proper thick ones, not the thin disposable type.
A plastic scraper or old credit card for stubborn buildup. Non-scratch scouring pads, never wire wool on enamel surfaces. Several microfibre cloths plus old towels you don’t mind ruining. A large bin bag or two for soaking racks.
Washing up liquid for the final wipe-down. Old newspaper or a drop cloth to protect your kitchen floor. A small bowl for mixing paste if using the bicarbonate method.
Safety First
Commercial oven cleaners contain strong chemicals. Always wear gloves, open windows for ventilation, and keep children and pets away until you’ve finished and wiped everything down completely.
Preparation Before You Start
Good preparation cuts your total cleaning time significantly. Skip these steps and you’ll struggle later. Trust us on this one-we learned through trial and error so you don’t have to.
Set aside at least two hours for a moderately dirty oven. Heavily soiled ones might need overnight soaking, which we’ll cover shortly.
Getting Ready
Make sure the oven is completely cold. This seems obvious, but we’ve seen burns from people too eager to start. If you used it today, wait at least two hours or until the next morning.
Remove everything inside. Take out all racks, trays, thermometers, and the grill pan. Even that pizza stone you forgot about. Everything comes out.
Lay protection on your floor. Oven cleaner drips. Grease runs. Old newspaper or towels beneath the door saves your flooring from damage and makes cleanup easier.
Disconnect if needed. For built-in electric ovens, switching off at the fuse box adds a safety margin. Gas ovens should have the supply turned off at the isolation valve.
Open windows. Even with gloves, the fumes from commercial cleaners can be intense. Good airflow protects your lungs and clears the smell faster.
Cleaning The Interior
Now the real work begins. The interior walls, floor, and ceiling of your oven need attention. This is where burnt-on grease lives and where most people give up too quickly.
You have two main approaches here: commercial cleaner for speed, or bicarbonate paste for a gentler option. Both work. We’ll cover each method.
Method One: Commercial Oven Cleaner
Spray the product generously across all interior surfaces. Cover the back wall, sides, floor, and ceiling. Avoid the heating elements directly-wipe around them carefully instead.
Close the door and wait. Most products need 20-30 minutes minimum. For badly neglected ovens, leave it several hours or overnight. The longer it sits, the easier scrubbing becomes.
Return with your scraper and scouring pad. Work in sections, scraping heavy deposits first, then scrubbing. Wipe away residue with damp cloths repeatedly until water runs clear.
Method Two: Bicarbonate Paste
Mix bicarbonate of soda with water until you have a thick, spreadable paste. About half a cup of powder with a few tablespoons of water usually works. It should hold its shape when applied.
Spread this paste across all interior surfaces using gloved hands or an old brush. Really work it into grimy areas. The paste will turn brown as it reacts with the grease-that’s good.
Leave overnight for best results. In the morning, spray white vinegar over the paste. It’ll fizz. Then scrub and wipe clean with damp cloths. Repeat vinegar spraying as needed.
Stubborn Spots
Some carbonised patches resist both methods. For these, apply cleaner or paste directly, cover with cling film to prevent drying, and leave longer. Repeat if needed. Patience beats elbow grease every time.
Racks and Trays
Those wire racks and baking trays need separate attention. They’re often the dirtiest parts but also the easiest to clean when you know the trick. Here’s how we handle them.
The bin bag method sounds odd but works brilliantly. It uses less product and lets everything soak properly without taking over your entire kitchen sink.
The Bin Bag Soak Method
Place racks in a large bin bag. Lay it flat in your bathtub, garden, or on protected flooring. The bag contains the mess and the cleaner.
Spray generously with oven cleaner. Coat all surfaces of the racks. Seal the bag and leave for several hours. Overnight works even better for heavy buildup.
Scrub in the bathtub or outside. The grease will have loosened considerably. Use a scouring pad and hot soapy water. Rinse thoroughly and dry before replacing.
For trays, use the same approach. Or fill your sink with hot water, add washing up liquid and a cup of bicarbonate, then soak for an hour before scrubbing.
Chrome vs Non-Stick
Chrome racks can handle aggressive scrubbing. Non-stick trays cannot-use only soft sponges on these. If the non-stick coating is damaged or flaking, consider replacing the tray entirely.
The Door Glass (Inside and Out)
Cloudy, brown door glass ruins the look of even a clean oven. But here’s the thing-most oven doors have multiple glass panels with gaps between them. Grease gets trapped inside.
Cleaning the outer and inner surfaces helps, but sometimes you need to access the space between. We’ll cover all three scenarios.
Outer Glass Surface
Use glass cleaner or a vinegar-water mix. Spray liberally and wipe with a microfibre cloth. For stubborn grease spots, apply bicarbonate paste, leave briefly, then wipe clean.
Avoid abrasive scourers on glass-they create fine scratches that trap dirt later. A razor blade scraper held at a shallow angle removes stuck-on drips without scratching if you’re careful.
Inner Glass Surface
This surface faces into the oven and takes the most abuse. Apply oven cleaner or bicarbonate paste just as you did inside the oven cavity. Let it work, then scrub gently.
The rubber door seal around the edge needs attention too. Wipe it down with soapy water-never use harsh chemicals here. Damaged seals affect oven efficiency and may need replacing.
Between The Glass Panels
Check your oven manual first. Many doors have a removable bottom panel or can be taken apart entirely. If yours allows this, remove the outer glass carefully and clean the inner surfaces.
Some ovens have slots at the bottom of the door. A thin tool wrapped in cloth can reach inside to wipe surfaces you can’t otherwise access. Work patiently-forcing anything risks cracking glass.
If dismantling seems too risky, leave this for professionals. Cracked oven door glass is expensive to replace and can be dangerous. Sometimes good enough is good enough.
Exterior and Finishing Touches
Nearly there. The exterior, control knobs, and surrounding surfaces deserve attention too. Fingerprints, grease splashes, and dust accumulate here more than you’d expect.
Different finishes need different approaches. Stainless steel behaves differently than enamel or painted surfaces.
Finishing The Job Properly
Pull off control knobs if possible-grease hides underneath. Soak them in warm soapy water while you clean the panel behind. Use a toothbrush for any buttons or crevices.
Stainless steel shows every fingerprint. Wipe first with soapy water, then buff dry following the grain direction. Baby oil or specialist steel polish adds shine and resists future marks.
Wipe down the surrounding countertop and splashback. Oven cleaning often splatters beyond the oven itself. A final once-over catches any drips or residue you might have missed.
The First Heat-Up
Before cooking again, run the oven empty at 200°C for 15-20 minutes with windows open. This burns off any remaining cleaner residue and eliminates chemical smells. Your next meal will taste like food, not fumes.
Keeping It Clean Longer
A deep clean takes effort. Wouldn’t it be nice to do it less often? Small habits make a genuine difference. None of these take more than a few minutes.
Maintenance beats major cleaning every time. Five minutes weekly prevents hours of scrubbing monthly. We’ve seen the difference across hundreds of kitchens.
Prevention Tips That Actually Work
Wipe spills immediately. When something bubbles over, wait for the oven to cool slightly, then wipe before it carbonises. Fresh spills come off easily. Baked-on ones don’t.
Use roasting bags or covered dishes. They contain splatters from meat and vegetables. Less mess reaches your oven walls in the first place.
Place a baking tray on the shelf below. It catches drips from whatever you’re cooking above. Much easier to clean a tray than the oven floor.
Quick-wipe after cooling. Once a week, give the interior a fast wipe with a damp cloth while it’s still slightly warm. Takes two minutes and prevents buildup.
Clean the door glass regularly. It’s visible, so you’ll notice immediately when it needs attention. Keeping on top of this makes the whole oven look cleaner.
