Cleaning Your Oven With Baking Soda

As the UK’s largest oven cleaning franchise, we know the best way to clean ovens with baking soda. You may have learned about this combination as early as nursery school, where it is often used to introduce kids to the concept of chemical reactions in a harmless environment.

Oven cleaning hacks using baking soda and vinegar find their roots in Chemistry. When vinegar (an acid) and baking soda (a base) meet, they chemically react together, resulting in bubbles and foam.

In the first reaction, the acid-based reaction, hydrogen ions in the vinegar react with the sodium and bicarbonate ions in the baking soda. This results in two new compounds: carbonic acid and sodium acetate.

In the second reaction, which is the decomposition reaction, the freshly produced carbonic acid decomposes into water and carbon dioxide gas, causing bubbles and foam to arise.

Using this recipe for cleaning oven with baking soda and vinegar can help loosen grease and grime from the inside of your oven, making it easier to remove. Although not as effective as professional oven cleaning, this is a wat to clean the oven naturally overnight.

How to Clean Your Oven with Baking Soda and Vinegar

  1. Gather seven tablespoons of baking soda (bi carb), 200ml of vinegar and four tablespoons water. Empty the oven completely, setting any trays, racks and oven dishes aside.
  2. Scrape Out the Loose Build-Up and prepare your vinegar. Pour your vinegar into a spray bottle. Scrape out any crumbs or burnt bits of food in the oven, with a spatula.
  3. Create a baking soda (bicarb) cleaning paste. To form your bicarb (baking soda) paste, in a regular bowl, mix seven tablespoons of baking soda (bicarbonate of soda) with three tablespoons of water until you have a spreadable cleaning paste. If you have a rather large oven or if you’re cleaning multiple ovens at once, you may consider doubling – or even tripling – the amounts. Don’t worry if your paste is not 100% consistent in texture.
  4. Coat the inside of your oven with the paste and leave overnight: Next, get your household gloves out and coat the inside surfaces with a sponge, using your hands and fingers to really get the paste into every nook and cranny. Pay extra attention to particularly greasy areas. As you rub in the paste, you’ll notice it will turn a brownish colour from the grime it is absorbing, so make sure your hands, arms and clothes are protected. Warning: make sure to steer clear of the heating elements when applying the paste.
  5. Let the Paste Sit Overnight: As some of the grease and grime inside your oven may be rather stubborn, leaving the baking soda paste to sit for at least 12 hours will produce the best results. Whilst this magical mixture does its job, you can get on with your day or have a good night’s rest.
  6. Wipe up the baking soda Paste: After the 12-hour work-in period, put on your household gloves again, take a damp dishcloth and wipe out the dried paste as good as you can; consider using a spatula to scrape the paste out of hard-to-reach corners. If you do use a spatula, make sure it’s a soft plastic or wooden one so it doesn’t scratch your oven.
  7. A Final Clean with Vinegar: Spray your vinegar onto the inside oven surfaces. The chemical reaction between the vinegar and the baking soda will produce foam and bubbles, which will loosen the leftover grime and identify any residue of paste.
  8. The Final Wipe Down: Take a damp dishcloth and wipe down any remaining foamy areas of the oven. Spray and wipe away the vinegar until your oven looks as clean as new.
