Cleaning with vinegar is a fool-proof method for many areas in the house, including the microwave. Vinegar has both antimicrobial and antibacterial properties and will clear your microwave of any nasties that may be lurking as a result of old food remnants.

Follow the steps below to learn how to clean a microwave with vinegar:

What you'll need

  • White vinegar
  • A microwaveable bowl
  • A bottle of a fresh and strongly scented essential oil that masks smells well, like Lemongrass or Rosemary which you can buy on Amazon
  • Water
  • Kitchen gloves
  • A clean cloth

1. Fill a bowl with water and vinegar

Fill a microwave safe bowl with 2 cups of water and 2tbsps of white vinegar.

2. Add an essential oil of your choice

Add a few drops of your favourite essential oil if you want to leave a nice scent - the only downside to cleaning with vinegar is the strong smell it leaves behind. We like a fresh scent like lemongrass essential oil from Nikura on Amazon to help mask the vinegar whiff.

Then, put the microwave on for 2-3 minutes on a high setting. Use oven gloves to remove your bowl.

3. Clean the microwave with the mixture

Dampen a clean cloth in the bowl and wipe down dislodged grease and dirt.

FAQs

Microwave steam cleaner – do I need to use one?

You can pick up portable microwave steam cleaners for under £10 on Amazon, such as the popular Angry Mama microwave steam cleaner, but you will still need to add a mix of water and white vinegar to them and it may prove just as easy to follow the tips above.

However, the benefit of microwave steam cleaners is that these products can be reused up to a hundred times and require minimal prep.

If your microwave is beyond saving with a deep clean, it might be time to look at our pick of the best microwaves, invest in a new model, and try your hand at cleaning this one more often.

How do you clean a microwave naturally?

'The best way to tackle unwanted smells and bacteria from a microwave is to fill a microwaveable bowl halfway with water and half a lemon,' says cleaning experts Steph and Jade.

'Heat on high for 3-5 minutes until boiling and leave the steam to work its magic. Once it’s cooled, wipe out with a microfibre cloth.'

Lemon is acidic enough to break down stubborn grease and leftover food stains, and it will work just as well if not better than cleaning products specifically formulated for microwave cleaning. Other natural products that work well are baking soda and vinegar. Trial out each one and see which you prefer.

The top tip for learning how to clean a microwave is to let a bowl of water mixed with either lemon, vinegar, or baking soda sit in the microwave for three minutes on high heat before you start scrubbing with a cloth. The steam created from the water solution will work wonders, and make cleaning ten times easier. 

'If you're still left with any stubborn marks after this, add a bit of plain white vinegar to a cloth,' says Lara Brittain, Kitchen Expert, Currys. 'And always leave the door of the microwave open for a few minutes to air after cleaning.'

What products can I use to clean inside the microwave?

Aside from natural cleaning agents such as lemon, vinegar, and baking soda, washing-up liquid is a tried and tested product that you can use to clean the microwave. You can use a little bit of washing-up liquid and water for more frequent cleans, then stick to the natural cleaning agents when the microwave needs a deeper clean. 

'Microwaves should be wiped out after every use and then cleaned fully with a warm damp cloth and a little washing up liquid once a week,' says Sophie Lane, Product Training Manager, Miele. 'Be careful not to use too much water as this can damage the appliance.'

Regular anti-bacterial cleaning sprays are fine to use inside the microwave as well. 'But you should never use harsh chemicals or bleach to clean your microwave,' says Lara from Currys.

No, there's no excuse for a grubby microwave, but give one of these easy cleaning hacks a whirl to make it gleam again. Problem solved.
