How to clean a microwave with lemon, washing-up liquid and baking soda

How to Clean the Inside of a Microwave

A combination of splatters and smells can leave your microwave looking, well, sad. To target your microwave’s interior – turntable included — follow this step-by-step:

  1. Combine 1 cup water and lemon, lime or orange slices (squeeze juice from the fruit slices into the water) in a microwave-safe bowl. Or, if you have white or apple cider vinegar on hand, combine a few tablespoons and 1 cup water in a microwave-safe bowl.
  2. Place the bowl in the microwave and turn it on high power for several minutes until the mixture boils and the window steams up.
  3. Let cool for 5 minutes before opening the door, then remove the bowl and wipe the inside clean with a sponge.

You will need

  • A microwave suitable bowl or jug large enough to hold around half a cup (200ml) of water
  • One whole lemon
  • A clean, dry cloth

This natural spring cleaning and all-year-round microwave maintenance method will help the environment, save you money and keep your family healthy too!

1. Simply cut your lemon in half (you could also use lime or an orange if you only have these citruses to hand) and squeeze the juice from one half into 200ml of water. 

2. Place both halves of the lemon, leaving the rind on, into the water. 

3. Turn the machine on high for several minutes (five should be fine) allowing the solution to boil and make the window steamy. 

4. Let the microwave cool a little and then simply wipe down the inside with a damp, clean sponge afterward.

5. Let the microwave dry out completely.

How to clean a microwave with baking soda

As baking soda is a mild alkali it’s perfect for cutting through grease and other dirt around your home, and that includes any that might have built up in your microwave. For this tip you’ll need to have some kitchen gloves and a clean cloth to hand.

  • Remove your microwave plate and turntable ring
  • Sprinkle 1/4 cup of baking soda around the bottom of your microwave
  • Use a dampened cloth to work the baking soda into any stains in your microwave
  • Rinse your cloth and wipe away any remaining soda. Do this twice if any residue remains

How to Keep Your Microwave Clean

The best and easiest way to prevent having to “deep clean” your microwave is to clean as you go. Wipe up any spills or spatters with a clean sponge, microfiber cloth, or paper towels after each use before they get hard and crusty.


Add a lemon juice or vinegar-and-baking soda cleanse to your regular weekly routine to keep your microwave interior bright and shiny. And while you are wiping things down inside the microwave, take a pass over the exterior surfaces as well, paying particular attention to the touch pad, where greasy fingerprints can build up over time.

Of course, one of the best ways to keep your microwave clean is to prevent food spatters and spills in the first place by using microwave covers over the food that you are heating. These handy kitchen accessories are typically constructed of plastic, silicone, or glass and come in various sizes and shapes to help contain messes.

Cleaning a Microwave with Vinegar or Lemon Juice

If you want a natural option, try cleaning your microwave with distilled white vinegar or lemon juice, which is effective due to its acidity. Mix a tablespoon with one cup of water and heat it in a microwave-safe container for 2 to 5 minutes to create steam. Then, wipe down all the interior surfaces. Keep in mind that lemon juice may leave behind a nicer scent than vinegar.

How to clean microwave filters

Now you know how to clean inside the microwave, it’s time to consider other areas you should clean. Most over-the-range microwaves have two filters — a charcoal filter to reduce odors, and a grease filter to prevent buildup in the exhaust fan mechanism. Both should be cleaned and/or replaced on a regular schedule.

Charcoal filters are usually located under the top vent panel. You’ll probably need a screwdriver to remove the panel to get to the filter. These filters should typically be changed every 6 months, but consult your microwave owner’s manual for specific instructions.

Grease filters are located on the underside of the microwave, and are easier to access. These filters should be washed once a month to remove accumulated grease. It’s easy to remove a grease filter, just slide it out of its housing. Then submerge it in a sink full of hot water, dish soap, and ¼ cup baking soda. Let the filter soak for 10-15 minutes, and then clean with a scrubbing brush, taking care not to bend the metal. Dry the cleaned filter and slide it back into position.

Additional Tips for Microwave Maintenance

Preventing a mess is the best way to keep your microwave clean, but how can you do that? Here are a few additional tips to help you keep it clean:

  • Cover the food: Covering the food you’re heating is the best and easiest way to avoid a mess. So if a slight sauce-explosion were to happen, the cover will help to prevent a mess.
  • Wipe it regularly: This is also an easy way to keep your microwave clean. After using the appliance, take a damp cloth and wipe down the sides, ceiling and turntable. Doing this regularly will help to prevent a nasty buildup of germs and gunk.
  • Go slow: If you’re heating liquid food, such as a sauce or soup, go slow. Set the time and heat to a reasonable setting and repeat if necessary. Spills and minor food explosions are more likely to happen when food overheats.

How to maintain a clean microwave

  • Daily wipe downs: In order to make it easier to clean your microwave next time wipe the inside of your microwave every day, depending on how often you use it.
  • Treat spills immediately: Try and remove any splattered food as quickly as possible, it’s easier to remove when the food is warm and yet to harden.
  • Anti-splash plate cover: Cover your food before cooking using something like an anti-splash plate cover, available from Amazon.

How often should you replace your microwave?

Most microwaves are manufactured to last up to 10 years. But, yours will only last that long if you maintain it properly and clean it frequently.

How to clean the microwave

You can use any all-purpose or DIY cleaning solution to clean your microwave. Simply spray the inside of the appliance, wait a few minutes, and wipe all surfaces with a microfiber cloth. The removable glass turntable can be cleaned in the same way, or if it’s very grubby, wash it in the sink with some dish soap.

Don’t use cleaners that are too harsh inside your microwave — remember, you’re going to eat the food that’s cooked in there. Bleach can damage the microwave surfaces, or leave an unpleasant residue behind. If you use any commercial cleaner, it’s always a good idea to give the microwave a final clean with fresh water once the stains and dried food have been dealt with.

Don’t forget the microwave door! If the window is looking greasy, use dish soap to cut through the buildup and make your microwave look like new again.

How to Clean Microwave Filter with Baking Soda?

If your over-the-range microwave comes with a vent hood, you should clean the filter underneath the microwave hood fan regularly. When there is visible grease on your microwave hood filter, it’s a clear sign that it needs some deep clean.

Step 2. Mix baking soda, dish soap and hot water in a bucket or a sink. Stir the mixture with a tool until the material blends.

Step 3. Soak the microwave filter in this baking soda solution for around 15 minutes. Before you take it out, check if the grease on it is loosened. If not, let the filter sit in this solution for a bit longer.

Step 4. After the immersion, the grease on the microwave filter should be loosened and dissolved from the surface. Now use a brush to scrub the filter until all grease falls off, then flush the whole filter with water to get rid of dish soap and baking soda.

Step 5. Let the microwave filter fully dry before tightening it back with the original screws.

Steam Clean Microwave

Sometimes foods with oils and sauces may burst up in the microwave and most of the time you will find yourself pushing the cleaning for another day. By the time you realize, your microwave will be all messed up with tough stains. If your microwave does not have unpleasant odors, you can heat a bowl with plain water and let it sit for a few minutes to loosen hard food particles making it easier to remove. Remove the tray and clean it separately.

Steaming with water is one the easiest ways to get rid of gunk and grime from your microwave. While you can steam with plain water, the addition of vinegar, lemon juice or baking powder helps to get rid of the odors too. These products also act as antimicrobials and bleaching that get rid of stubborn stains.

Do not forget to clean the exterior of your microwave.

What Youll Need


  • Lemon, orange, or lime slices
  • Distilled white vinegar
  • Baking soda
  • Dishwashing liquid with grease-cutting ingredients
  • Melamine sponge (Mr. Clean Eraser)


  • Microwaveable glass bowl or cup
  • Sponge or microfiber cloth
  • Dishwasher
  • Sink or large tub

What is the best way to clean the inside of a microwave?

The best way to clean the inside of a microwave is with lemon. It only requires one lemon, a heat-resistant dish, some water, and a cloth! The microwave does all the work for you, so all you have to do is wipe.

That being said, whether you use lemon, baking soda, vinegar, or dish soap to tackle tough stains, follow the tips in this article and you will be left with a super shiny appliance.

Other Ways to Deodorize the Microwave

If your microwave is clean, but still has an unpleasant odor from your lunch last Tuesday, you need to deodorize it. This is quickly done using one of these methods:

1. Vinegar and Baking Soda

Start by soaking a sponge in pure white vinegar. Place it in the middle of the microwave and sprinkle a generous amount of baking soda on top of the sponge.

Microwave it until it’s warm (about 25 seconds), carefully check the sponge before grabbing it. When you feel confident that it won’t burn you, use the sponge with vinegar and baking soda to wipe down the microwave.

The baking soda will effectively absorb odors while the vinegar neutralizes odors and disinfects. This should get rid of any unpleasant odor in your microwave.

2. Baking Soda

If you don’t have time to clean the microwave but need to get rid of a stench, try this method. Open up a box of baking soda, place it in the center of the microwave, shut the door and leave it overnight. This method is often used to deodorize other areas, such as cabinets, refrigerators and even cars.

3. Lemon Juice

Add five tablespoons of lemon juice to a microwave-safe bowl. Place it in the microwave and heat for five minutes. When it’s finished, keep the door shut for one hour to allow the lemon to deodorize the space.

4. Vanilla Extract

In a microwave-safe bowl, pour in two cups of warm water. Add two teaspoons of vanilla extract and place the bowl in the microwave. Heat until the water boils — about three minutes. Once it’s done, keep the door shut for 30 minutes.

5. Cloves

In a small bowl, add a quarter of a cup of cloves. Simply place the bowl inside the microwave, shut the door and leave it overnight. Cloves have a strong scent and can neutralize odors.

How to Clean a Microwave Turntable

Your microwave’s turntable can be cleaned separately from the rest of the oven. 

Step 1: Check if the microwave turntable is hot

Wait for the turntable to completely cool before washing it. The glass could shatter if exposed to water while it’s still hot. 

Step 2: Wash in the dishwasher or by hand

Many turntables are dishwasher-safe. Check for a dishwasher-safe symbol engraved somewhere on the turntable or reference your microwave’s owner’s manual. If not, hand wash it with a soft sponge and liquid dish soap. 

Step 3: Rinse with clean water and dry

Run the turntable under warm running water to rinse it clean. Dry it with a soft drying towel and replace before using the microwave again.

How to Clean a Microwave with Vinegar and Baking Soda

Vinegar and baking soda combine to create a powerful cleaning agent. Both are inexpensive, and most people tend to keep a box or bottle of each item on hand. (Also, it’s worth mentioning that vinegar acts as a natural disinfectant.)


  1. Add four tablespoons of baking soda to a quart of warm water, being sure to mash and stir so that the powder fully dissolves.
  2. Dip a cloth or sponge into the mixture, repeating as necessary, and wipe down the entire interior.
  3. Pour one-half cup of water and one-half cup of white vinegar into a small, microwave-safe bowl.
  4. Place the bowl in your microwave, running the appliance on high for two or three minutes—long enough for the water to boil vigorously.
  5. Keeping the microwave door closed, let the bowl stand for about 10 minutes while the steam works its magic.
  6. Open the microwave door, take out the bowl, and remove the turntable (if your microwave has one), along with its carousel. Soak these parts in hot, soapy water.
  7. Clean the microwave interior with the vinegar-and-water solution you’ve prepared. Keep at the task until no baking soda residue remains inside the oven.
