Cleaning How-To

How to Clean Your Oven Naturally (Without Harsh Chemicals)

Commercial oven cleaners work, but they're harsh, smelly, and full of caustic chemicals you'd rather not have near your food or your family. The good news: you can get a genuinely clean oven using two cheap things you probably already have, bicarbonate of soda and white vinegar. This method takes a little patience (most of it is hands-off waiting), but it's safe, low-fume, and surprisingly effective on baked-on grease.

Why clean your oven naturally?

Caustic oven cleaners rely on strong chemicals that produce fumes and can irritate skin, eyes and lungs. Switching to bicarb and vinegar avoids all of that. It's safer if you have kids, pets or asthma, it's far cheaper, and it leaves no chemical residue near the surfaces your food touches. The trade-off is time: natural cleaning works through soaking rather than instant chemical action, so you'll want to start the night before.

What you'll need

• Bicarbonate of soda (baking soda), about half a cup
• White vinegar in a spray bottle
• Water
• A few drops of dish soap (optional, for extra grease-cutting)
• A damp cloth, a non-scratch scourer or old toothbrush, and rubber gloves

Step-by-step: the bicarb and vinegar method

1. Remove the racks and anything else from inside the oven so you can reach every surface. Set the racks aside to clean separately.
2. Make a paste by mixing about half a cup of bicarb soda with a few tablespoons of water until it's spreadable, like a thick frosting. Add a few drops of dish soap if your oven is especially greasy.
3. Spread the paste over the interior surfaces, avoiding the heating elements and the fan. Focus on the greasiest spots and the glass door. It may turn brownish as it contacts grease, which is fine.
4. Leave it to work overnight, or for at least 6 to 8 hours. This soaking time is what does the heavy lifting, so don't rush it.
5. Wipe out as much paste as you can with a damp cloth. For stubborn spots, use a non-scratch scourer or an old toothbrush.
6. Spray white vinegar over any remaining bicarb residue. It will fizz as the two react, helping lift the last of the grime. Wipe clean with a damp cloth and repeat until no residue remains.
7. For the racks, soak them in a bath or large tub of hot water with bicarb and a little dish soap for a few hours, then scrub and rinse.

Cleaning oven glass naturally

Oven door glass responds especially well to a thicker bicarb paste. Spread it on, leave it for 30 minutes to an hour, then scrub gently in circular motions and wipe away. Repeat for stubborn baked-on layers. A little vinegar spray at the end leaves the glass streak-free.

How to keep your oven cleaner for longer

• Wipe up spills as soon as the oven is cool, before they bake on.
• Use a baking tray or oven liner under dishes likely to drip.
• Do a quick bicarb wipe-down monthly so grease never gets the chance to build up.

Frequently asked questions

Will vinegar damage my oven?

Used as described, diluted and wiped away, white vinegar is safe for oven interiors. Avoid getting any liquid on the heating elements or fan, and never use vinegar on a self-cleaning oven's special coating without checking the manual.

How long does the natural method take?

Active time is about 20 to 30 minutes, but you need to allow 6 to 8 hours (ideally overnight) of soaking in between. Plan for an evening start and a morning finish.
