Key Steps:

Don’t be a lemon, use a lemon! Citrus fruit is an easy and natural way to a fresh-smelling, clean microwave oven.

  1. Fill a bowl with water halfway.
  2. Cut a lemon in half. Then squeeze the lemon juice into the water and drop the halves into the bowl.
  3. Put the bowl in the microwave and heat for 3-5 minutes, or until boiling. Keep an eye on the microwave during this process.
  4. Leave to stand for 5 minutes. Keep the microwave door shut, as the steam inside will help to loosen food particles.
  5. Carefully remove the bowl and use a warm, damp sponge or cloth to wipe the insides of the microwave ­– don’t forget the door! Any food stains should now wipe off easily.

We all know how important it is to keep a high standard of hygiene around food. While cleaning a microwave oven can seem like a chore, it’s something that should be done on a regular basis to keep appliances energy-efficient and germ-free. Closing the door and forgetting about the stains is all too easy with a microwave (out of sight, out of mind and all that!) but burnt-on food can cause electrical sparking and affect the microwave’s performance. Here’s how to clean a microwave oven and keep it in great condition.

To remove grease and grime from the outside of your microwave, use a multipurpose cleaner like Cif – it lifts dirt without the need for scrubbing.

What is the Best Way to Clean a Microwave? The Traditional Way

When it comes to cleaning your microwave, it’s a good idea to check what the manual says before attempting any of the methods below. Most manufacturers recommend a method similar to the following steps for cleaning a microwave:

  • Prevent splatter by loosely covering food with microwavable plastic film or other items like a lid or paper towel when using the microwave.
  • Avoid food explosions by ensuring covered containers allow steam to escape, and are made of microwavable materials.
  • Never put metal, wood, or certain plastics into a microwave.
  • Clean up any spills straight away.
  • Clean regularly with water, an anti-bacterial spray, and a soft, non-abrasive cloth. Check labels to choose a product that’s suitable for cleaning a microwave, and always follow the manufacturer’s instructions to get the best results and avoid damaging your appliance.
  • Consult the manual for specific care instructions.

What is the Best Way to Clean a Microwave? A Guide to Easy Methods

Steam cleaning your microwave comes in three easy ways. Each ‘cooks’ a different item coated in or containing water for a specific length of time to produce steam, which helps shift those stubborn stains. Make sure you watch the process closely when doing this, as continuing to heat your cloth or bowl once the water has evaporated can be unsafe.

1) A paper towel

  • Soak a folded paper towel in water.
  • Place it on the glass turntable.
  • Microwave on ‘high’ for 60 seconds until steam is produced. Pay attention to this process – don’t get distracted and walk away from the microwave!
  • Leave for 5-10 minutes to cool.
  • Use the paper towel to wipe down the inside of the microwave.

2) A cotton dishcloth

  • Soak the cloth in water and place it on the glass turntable
  • Soak the cloth in water and place it on the glass turntable
  • Microwave on ‘high’ for 3 to 4 minutes
  • Pay attention to this process – don’t wander off and start doing something else!
  • Wait for 5 to 10 minutes for the dishcloth to cool down and be careful when removing it from the inside of the machine.
  • Use the dishcloth to wipe down the inside of the microwave.

3) A cup or bowl of water

  • Fill a small microwavable cup or dish halfway with water.
  • Place it in the centre of the glass turntable.
  • Microwave on ‘high’ until the water reaches a rolling boil (2 to 3 minutes on most machines).
  • Pay attention to this process – again, keep your eyes on the microwave!
  • Wait for 5 to 10 minutes while the water cools down.
  • Carefully remove the cup or bowl from the machine and use a cloth or paper towel to wipe down the interior.
