How to clean the microwave with lemon juice

The humble lemon is always a great place to start if you’re look for ways to clean the microwave. Here’s how you do it:


In-between cleans, the best microwave cleaning trick of all is to avoid the grime in the first place. Make a habit of wiping up spillages as soon as they occur using a piece of absorbent kitchen roll. Plenty Handy Towels come in convenient single sheets, so you can keep them on hand to pick up quickly whenever you need to tackle a spill.

  1. Pour around 150 ml of water into a microwaveable cup or bowl.
  2. Slice a lemon in half and squeeze in the juice (get the kids to help you with this bit).
  3. Drop the lemon halves into the bowl and microwave on a high power for two minutes.
  4. Let the lemon-juice-infused steam do its work for five minutes.
  5. Lemon juice is one of the best ways to clean the microwave interior, too, so remove the microwave plate (if you have one) and scrub it in the sink before rinsing.
  6. Wipe the inner walls, the door and the outside of the microwave down with a moistened paper towel that’s strong when wet, like Plenty Original.
  7. For any stubborn stains, dip your Plenty paper towel in the remaining lemon juice and work it a little harder.
  8. Dry the microwave with the paper towel and replace the microwave plate.


The best microwave cleaning trick is to prevent grime from sticking in the first place. Encourage the whole family to wipe up spillages as soon as they occur with an extra-absorbent sheet of Plenty kitchen roll. They’re super strong when wet, so one sheet is enough to clean up all sorts of spills – getting the job done efficiently to reduce household waste.

Final Thoughts

Keeping your microwave oven clean is the best way to ensure efficient, trouble-free operation and garner the maximum usable life expectancy out of your unit…to say nothing of keeping your kitchen clean and odor-free! To keep things simple, establish a regular cleaning routine using these tips on how to clean your microwave.

What cleaning products can you use in a microwave?

‘The combination microwave is, without doubt, the Swiss army knife of home appliances, perfect for everything from reheating a hot beverage or snack, to preparing a fresh roast dinner for you and your family,’ says Thomson.

‘But that versatility can mean that your slimline microwave needs a little tender loving care from time to time. It’s a busy home appliance and like any often-used appliance, keeping it clean can sometimes seem like a challenge.’

‘No matter how careful you are, food will invariably spill, bubble, and splatter the inside of your microwave. If you wipe it away straight away, then all is good. However, few of us have the time to do that, and if you are halfway through cooking a fresh, healthy meal it just isn’t practical. So the chances are that the inside of your combination microwave will benefit from regular cleaning, but with what exactly?’

‘Before you reach for one of the multitudes of harsh and often abrasive chemical cleaners, it is worth bearing one or two things in mind; firstly and very conveniently, the Panasonic range of slimline microwaves all have sleek stainless steel interiors.’

‘That means something very important; cleaning them is a lot easier. So leave those harsh, foul-smelling, and often irritating cleaning products on the supermarket shelf, because keeping your combination microwave clean, with simple, natural products is an easy and far more sustainable possibility, one which is better for you, better for the environment, and much better for your home appliances.’

How often should you clean your microwave?

Clean your microwave once a week to once every three to four weeks to keep the bacteria build-up and strong smells down in your kitchen. If you heat a lot of messy foods like sauces or gravy, you may need to clean it more often. Or, if you rarely use it, you can go longer than a month without cleaning it. Just don’t let the grime sit for very long.

Step 8: Add Sugar to Hot Lemon Juice and Water

Add sugar to the hot lemon juice and water.  I like to put three tablespoon-fulls in. You could do this right after you pull it out of the Microwave, while it is nice and hot.

Cleaning the Exterior

Cleaning the outside of the microwave is generally much easier, but it is a twofold task. First, you’ll want to use your water and vinegar solution to scrub the door, window, top, sides, and handle. Then rinse with a damp cloth as usual.

For the door gasket, you’ll need to use a bit more caution. You can use your water and vinegar solution on all the plastic parts of the appliance, but you must be careful to use only a water-dampened cloth on the rubber gasket along the edge of the microwave. Once all parts have dried, your microwave should look good as new.

Shower screens

To get rid of watermarks and limescale on your shower screen, Lynsey recommends chopping a lemon in half and covering the chopped side in baking soda.

Squeeze the lemon so its juices begin to squirt out.

Using the lemon, massage the baking soda and lemon juice mix onto your shower screen.

The abrasiveness of the baking soda and the lemon juice should remove any limescale and soap scum.

How do you clean a microwave with vinegar and water?

If you don’t have baking soda or a lemon, vinegar and water is a third effective way to clean your microwave.

White vinegar is best for this household chore; buy yours from Amazon here.

The ratio of vinegar to water is more or less up to you. Just be sure to dilute your vinegar with some water to decrease the strength. For easy stains, one tablespoon vinegar to one cup water will likely do the trick. If this doesn’t work for you, add more vinegar.

You can go all the way up to a 2:1 ratio of vinegar to water (⅓ cup water to ⅔ cup vinegar) if the stains just won’t budge. But, this is most commonly used for tough grease and mold. One to one, or more heavily diluted solutions, are much more popular options to clean your microwave.

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 Clean Greasy Microwave Doors

It’s not just the inside that counts: Remove smudges and grease from the microwave’s exterior with these tips and tricks.

  1. Clean the entire door — edges, both sides and where it seals the oven — with a sponge dampened with water and dipped in a little baking soda. Wipe with a damp cloth or sponge to rinse.
  2. For a greasy window, clean with a 50/50 mixture of vinegar and water. Rinse and wipe dry.
  3. For heavy grease build-up and stuck-on splatters, wipe your microwave door down with an all-purpose, grease-cutting cleaner (like Mr. Clean Clean Freak Mist) or a sudsy mix of dish soap and water. Apply the cleaner with a cloth or sponge to prevent cleaner from getting into the vent holes. Scrub with a non-scratch pad (such as Scotch-Brite), if needed. Similarly, never spray electronic controls directly with cleaner to avoid damage. Always apply the cleaner to a cloth first, then wipe the controls.

Step 4: Pour the Lemon Juice Into the Microwave-safe Cup

Pour the lemon juice and pulp into the Microwave-safe cup with one cup of water. I like to keep the pulp in the juice, so I do not strain in this step.

How to Clean a Microwave with a Commercial Cleanser


Various commercial cleaners on the market are geared toward cleaning microwaves and other appliances. Many of these cleaners produce strong and sometimes quite unpleasant fumes, which linger in the microwave and can make your food taste a little off. If you want to try a commercial cleaner, consider purchasing a fume-free product and letting the door stand open for a couple of hours after you finish cleaning. Also, always thoroughly rinse the interior with water after using a commercial cleanser.


Of course, the more often you use the microwave, the more frequently you should clean it. For the average homeowner, cleaning the microwave once every two weeks is an appropriate schedule if you want to keep the appliance looking—and smelling—its delightfully clean best.
