Microwave cleaning is one of those tedious tasks that no one likes to do. But, you need to do it regularly to maintain the appliance and ensure good cleanliness without bacteria and bad odours. Whether you have a freestanding or built-in model, we want to introduce you a few different ways how to clean microwave oven in a safe way.

Before cleaning

Before following any of our cleaning tips, make sure you unplug the appliance. In fact, this is the perfect time to check the power lead. Look for dirt or damages that can pose a potential fire. If everything looks normal, clean the accumulation of dust and dirt.

The next step before moving on to cleaning the microwave itself is to look inside to determine where most of the dirt has accumulated. It is also good to be clear with the moving parts of the model. This will allow you to prepare the dirtiest items in advance so that you are comfortable in the cleaning process.

1. Clean microwave with lemon

This is one of the easiest ways to clean a microwave oven. For this, you will need a few things that you can find in any kitchen. Take a bowl that is suitable for microwave and fill it with water. Then cut two lemons into four pieces, squeeze the juice of one in the water and leave the other pieces whole. You can also add a teaspoon of baking soda to better remove odors. Then place the bowl in the oven and set it for 4-5 minutes. Water will help create steam, and lemon will act as a disinfectant. As soon as the minutes have elapsed, you must wipe the inside of the oven with a suitable dry cloth.

Step-by-step instructions:

  • Fill a bowl with water
  • Cut 2 lemons, squeezing one in the water
  • Add baking soda (optional)
  • Run the microwave for 4-5 minutes
  • Wipe with a dry cloth

2. Cleaning with wet wipes

Another quick method of cleaning a microwave oven is to put soaked wet wipes inside and run it at full power for about 4-5 minutes. The created steam will soften the dirt accumulated on the walls. Once the wipes have cooled, you can use them to wipe the interior.

  • Wet wipes
  • Run the microwave at maximum power
  • Wipe the inside of the oven

3. Clean the microwave with baking soda

To remove food debris from the walls or plate of the microwave, make a cleaning paste by mixing two parts baking soda with one part water. Apply it on dirty areas and leave for a few minutes. Wipe the soda with a damp cloth using light pressure, then wipe with a clean, dry cloth.

In case of stubborn dirt, repeat the steps several times or combine with one of the other methods.

4. Water and vinegar

Fill half a glass or bowl with water, add a tablespoon of white vinegar. Run the microwave for five minutes on high power. This process will steam the walls of the microwave and soften the dried dirt. Carefully remove the bowl of water and vinegar and wipe the inside of the microwave with a clean, dry cloth. Take out the glass plate and wash it with warm water and faith. If you have a dishwasher, you can use it instead of washing by hand.

5. Solution with vinegar and baking soda

This is a method of cleaning the microwave with two cheap ingredients that most people have at home.

  • Add four tablespoons of baking soda to a litre of warm water. 
  • Stir the solution well so that the soda dissolves completely. 
  • Dip a cleaning cloth or sponge into the liquid and wipe the entire inside of the microwave well.
  • In a suitable bowl, place equal parts of water and white vinegar. 
  • Put it in the microwave and turn on for about three minutes on high power or until the water boils. 
  • Don’t open the microwave door for 10 minutes to allow the steam to do its job. 
  • Open the door and remove the bowl, glass plate and roller. 
  • Soak the parts in hot soapy water while wiping the inside of the microwave.

6. Cleaning with washing up liquid

Use a safe bowl suitable for microwave. Fill it with water and washing up liquid. Put in the oven for a minute or two until it starts to evaporate. Then wet a towel and wipe the inside of the microwave. The steam will soften any stains on the walls of the microwave so you can easily clean it. You can also add baking soda to the bowl to remove bad odours.

7. Diluted window cleaner

In a bowl, mix one part window cleaner with one part water. Soak a cleaning sponge in the mixture and wipe the inside of the microwave. Remove the plate and clean the bottom, making sure you remove all stains. 

Clean the rest of the inside to eliminate any residue. In the presence of stubborn stains, wet the surface with the prepared solution and wait ten minutes. Be sure to pay attention to the ceiling, as in most cases the food is sprayed on the top of the microwave.

Once the inside is shiny, soak a towel in clean water and wash it once more. This is necessary for the complete removal of the solution, as it contains chemicals. 

Smell the inside and make sure the inside doesn’t smell of window cleaner. If necessary, clean again with clean water.

8. Microwave cleaner

Several types of detergents can adequately clean almost any dirt in your microwave. But they contain chemicals that often create unpleasant fumes that remain in the microwave. Some of the detergents can give a bad taste to food when you use the oven.

If you use a detergent, choose a product that doesn’t evaporate and leave the door open for a few hours after you have finished cleaning. 

Always be careful when using any detergents for your microwave oven. Never combine the above methods with strong detergents. In the case of heating, they can be explosive.

Microwave cleaning tips

Avoid overflow

If you choose one of the ways we mentioned to you with the bowl, then you should pay special attention to the following advice. Adding vinegar to water and heating it can have the opposite effect than expected. You should avoid possible spillage of the mixture. This is quite possible if the water reaches a boiling point. You can solve the problem by placing a toothpick or a small wooden spoon in the bowl. 

Use a microwave lid

Emphasize the top of the microwave. This is where most of the dirt collects most easily. Food splashes stay there, even if you’ve used the microwave once. To prevent this, buy a microwave lid that covers the food. You have no idea how much cleaning this gadget will save you.

Clean the glass plate and the roller

Don’t just focus on cleaning the walls of the microwave. Remove the glass plate, the roller and wash them gently with hot soapy water.

Then, clean the walls and bottom of the oven. Be sure to rinse the towel regularly so that it doesn’t smudge the dirt on the already cleaned areas.

Once you have cleaned the inside, move to the outside of the microwave. Start from the top to the side, the back and finally the front. Dry the roller and the glass plate, then you can plug the microwave back into the socket.
