How to Clean an Oven Naturally: Step-by-Step Guide

Baked-on grease and grime build up in every oven eventually, and reaching for a harsh chemical spray is not the only option. This guide covers how to get your oven properly clean using baking soda, vinegar, and steam, all without the strong fumes that commercial oven cleaners can bring into your kitchen.

How Do You Clean an Oven Naturally?

To clean an oven naturally, mix baking soda with a little water into a spreadable paste, coat the interior surfaces, leave it to sit overnight, then spray with white vinegar and wipe clean. The vinegar reacts with the dried baking soda to lift baked-on grease and grime without harsh chemical fumes.

What You Will Need

  • Bicarbonate of soda (baking soda)
  • White vinegar
  • A spray bottle
  • Rubber gloves
  • A soft cloth or sponge
  • An old towel to protect the floor

How to Clean an Oven: Step by Step

1. Remove the Racks

Take out the oven racks and any removable trays. These can soak separately while you work on the oven interior, which makes both jobs easier.

2. Clear Out Loose Debris

Vacuum or brush out any loose crumbs, ash, or food particles from the bottom of the oven before applying anything wet. This makes the rest of the cleaning process considerably less messy.

3. Make the Baking Soda Paste

Mix bicarbonate of soda with a small amount of water until it forms a spreadable paste, roughly the consistency of thick toothpaste. Add water gradually rather than all at once, since it is easy to make the mixture too runny.

4. Apply the Paste

Wearing rubber gloves, spread the paste generously over the interior surfaces of the oven, including the sides, bottom, and inside of the door glass. Avoid the heating elements at the top or bottom, since these should not be coated in paste.

5. Leave It to Work

Leave the paste to sit for at least several hours, ideally overnight. This gives it time to soften and lift baked-on grease rather than sitting on the surface untouched.

6. Wipe It Clean

Using a damp cloth, wipe away as much of the dried paste and loosened grime as you can. A plastic scraper can help with any stubborn patches, though metal tools should be avoided, since they can scratch the oven’s interior surface.

7. Spray With Vinegar and Wipe Again

Fill a spray bottle with white vinegar and spray it over any remaining residue. It will fizz slightly as it reacts with the leftover baking soda, helping lift the last of the grime. Wipe the whole interior clean with a fresh damp cloth.

8. Clean the Racks

Soak the racks in a bath or large basin of hot water with a squeeze of washing-up liquid for at least an hour, then scrub with a sponge or soft brush before rinsing and drying.

Alternative Method: Steam Cleaning

For a lighter clean, place an oven-safe dish of water inside the oven and heat it to around 120°C for 20 to 30 minutes. The steam loosens grease and grime, making it easier to wipe away once the oven has cooled, without needing baking soda or vinegar at all. This method works well for regular light maintenance rather than heavily baked-on buildup.

Cleaning the Outside of the Oven

For painted or enamel exteriors, warm soapy water and a soft cloth are usually enough. Stainless steel surfaces benefit from a dedicated stainless steel cleaner to avoid streaking, and glass cleaner works well on the door glass and control panel. Avoid excess liquid around control panels and buttons, since too much moisture can affect the electronics.

How Often Should You Clean Your Oven?

A light interior wipe after any spill, plus a full deep clean every one to three months depending on how often you cook, keeps grease from building up into a stubborn, harder-to-remove layer. Regular light cleaning ultimately means less scrubbing at each deep clean.

Frequently Asked Questions

How long should baking soda paste sit in the oven before cleaning?

Leaving it overnight, or at minimum several hours, gives the paste enough time to soften baked-on grease properly before you wipe it away.

Is it safe to use vinegar and baking soda together in an oven?

Yes. The reaction between the two is mild and commonly used for cleaning, though it will fizz briefly. Always ensure the oven is switched off and cool before applying either product.

Can I use the self-cleaning function instead?

If your oven has a self-cleaning function, it can be effective, but it produces high heat and strong odours, so ensure the kitchen is well ventilated and check your oven’s manual, particularly for older appliances, before using it.

How do I clean burnt-on food from the bottom of an oven?

A thicker application of baking soda paste left for longer, followed by a vinegar spray, usually loosens even stubborn burnt-on food. A plastic scraper can help lift the softened residue without scratching the surface.

Why avoid harsh chemical oven cleaners?

Many commercial oven cleaners contain strong chemicals that can irritate the skin, eyes, and respiratory system, and require good ventilation and protective gloves. Natural alternatives avoid these fumes while still being effective on most everyday grease and grime.


Always ensure your oven is switched off and fully cool before cleaning, and check your appliance’s manual for any specific manufacturer guidance on cleaning products to avoid.
