How to Clean an Oven with Bicarbonate of Soda Paste Overnight

Cleaning an oven is not always straightforward, particularly when burnt-on grease and residue have built up over time. One of the best-known home methods is to make a bicarbonate of soda paste and leave it to work overnight. Allowing it to sit helps soften some of the grime, making it easier to remove the following day without needing as much effort during cleaning.

Why leave bicarbonate of soda paste to work for several hours?

Bicarbonate of soda is widely used for household cleaning because of its mildly abrasive action. Once combined with water to create a paste and spread over the dirt, it stays in contact with the residue for several hours, helping to loosen it gradually.

This resting time is particularly helpful for dried grease and burnt splatters, which often stick to the oven's inner walls. After the paste has worked for an extended period, less scrubbing with a sponge is generally needed.

How do you make a bicarbonate of soda paste to clean the oven?

The mixture is easy to prepare and requires just two ingredients. In a container, combine bicarbonate of soda with small amounts of water until you have a thick paste that is easy to spread.

Then spread the mixture over the internal walls of the oven, avoiding heating elements and any parts the manufacturer identifies as areas where cleaning products should not be used. Leave it in place overnight, then wipe away the paste the next day with a damp cloth.

• 120 ml bicarbonate of soda
• Enough water to make a paste
• A container for mixing
• A spatula or spoon for application
• A microfibre cloth
• A soft sponge to finish cleaning

How should you remove the paste and finish cleaning the oven?

Once the resting period has passed, use a damp cloth to remove most of the paste. If any bicarbonate of soda residue remains, wipe it again with another clean cloth until the product has been fully removed.

Any small grease marks left behind will usually come away more easily after the paste has worked. Once cleaning is complete, leave the oven door open for a few minutes so it can dry fully before using it again.

• Apply the paste only when the oven is completely cold
• Do not wet electrical components
• Use a microfibre cloth to remove the paste
• Repeat the process in very greasy areas
• Finish with a clean, dry cloth
• Clean the oven regularly to prevent fresh build-up

What precautions should you take when using this method?

Although bicarbonate of soda is regarded as a mild product, it is important to check the oven manufacturer's guidance before cleaning. Some models have special coatings that require particular care.

It is also not advisable to mix bicarbonate of soda with chemical products unless the manufacturer advises it. Using water alone to make the paste is normally enough for routine cleaning.

Try this method to make oven cleaning easier

Leaving bicarbonate of soda paste to work overnight can make removing grease and accumulated dirt far more manageable. With only a few ingredients and a little patience, you can reduce the effort needed to clean the oven.

When this step becomes part of the kitchen-cleaning routine, less residue builds up and the oven stays clean for longer, making everyday maintenance easier.
