How to remove odours from microwave oven with natural remedies is easy and satisfying. See a step-by-step guide below:

White vinegar

Boil a cup of water with four tablespoons of white vinegar in the microwave for just four minutes

Once the solution is steaming let it stand for another five minutes before opening the door

Wipe out the oven with a damp cloth or paper towel keeping the bowl inside for another 15 minutes for a refreshing scent

Lemon juice

Keep the door closed for an extra five minutes to let the steam penetrate through.

Baking soda

  • Dipping a sponge into a mixture of five teaspoons of baking soda with 0.95L of warm water
  • Use the solution to thoroughly cleanse all parts of the oven by wiping in a circular motion

Adding Finer Scents


Put two tablespoons of ground coffee mixed with half a cup of water into the microwave and heat for around three minutes to give a smell of fresh coffee


Put a bowl of cloves in the oven and leave overnight to add a spicy aroma without any heating at all


You can create a sweeter smell by heating four teaspoons of vanilla extract with two cups of water and heating for a couple of minutes to steam. Leave the container in for about 30 minutes to ensure the scent penetrates throughout


A covered bowl of berries microwaved for a few minutes will spread a fruity scent and cancel out any unpleasant smells along the way

Preventative Maintenance

How to maintain a microwave oven is quite simple if you just follow these guidelines:

  • Keep the interior cabinet clean by wiping down regularly with a mild detergent solution. This will stop any food residues absorbing energy resulting in the oven becoming less efficient. Mop up any spills immediately
  • Wipe down the outside of the oven to avoid residues building up on the control panel
  • Use microwaveable containers and cover food with microwave-safe plastic to prevent splashes hitting the walls or the ceiling of the oven
  • Don’t use metal or foil containers as this can damage the oven as emitted microwaves bounce off these materials
  • Make sure the door closes properly to stop radiation escaping and food not cooking evenly
  • Avoid running on empty as components aren’t designed to withstand the energy absorption caused
  • Call in the professionals if you experience any problems to see if the oven is worth repairing
