Cleaning the microwave is not a particularly fun chore, though. A clean oven keeps your kitchen hygienic, fresh, good, and free from bad smells. Food particles and grease quickly build up inside, affecting both appearance and performance. Cleaning a microwave is simple and requires only a few household items. For some, the microwave oven is one of the hardest-working appliances in your kitchen.
From reheating coffee to cooking or microwaving quick dinners, it’s probably used multiple times a day. But because most of its messes are hidden behind a closed door, it’s easy to ignore the splatters and spills building up inside. That is until a funky smell reminds you it’s time for a deep clean. And by then, it’s usually a tougher job.
The truth is, your toaster oven needs regular attention to keep it safe, sanitary, and working efficiently. In this post, we’ll cover how often to clean it, why cleaning it matters, and what products work best for the job. Food particles and moisture create a breeding ground for bacteria if left uncleaned. In a dirty microwave, bacteria build up quickly. A dirty stainless steel microwave can also reduce efficiency and produce unpleasant smells during use. Once you know how to clean a microwave the right way, keeping it spotless becomes effortless.

Quick Glance—How to Clean a Microwave?
The easiest method is to take water in a bowl and mix it with lemon juice, vinegar, or a some drops of dish soap. Heat the compound in the microwave to create steam. Let it sit for a couple of minutes, then wipe the microwave interior with a soft cloth or sponge. For the microwave exterior, use the same cloth with a little dish soap to remove the fingerprints and the splatter. Remove the turntable and wash it separately for a complete clean.
In the sections below, we’ll cover the essential tools you’ll need, explain why regular cleaning matters, and walk you through the best techniques to keep your toaster oven fresh and spotless.
Why Should You Clean Your Microwave?
A dirty microwave isn’t just unpleasant; it can also cause problems you might not expect:
- Odors stick around. Old food particles absorb and release smells every time you cook. Yuck!
- Bacteria can multiply. Remaining food and moisture create the ideal environment for germs to grow.
- Cooking performance suffers. Built-up grime can absorb heat, making cooking less efficient.
- Lifespan may shorten. Sticky messes can damage the interior finish or even clog vents over time.
Keeping your microwave clean is part of protecting your investment and your health.

What Are the Best Natural Microwave Cleaning Methods?
In this section, we are going to learn easy and effective natural cleaning methods to remove stains, eliminate smells, and keep your toaster oven sparkling clean with minimal effort.
How to Clean a Microwave With Lemon Juice and Steam
| Cleaning time: 7 minutes | Ease of use: 3/5 | Performance: 4/5 | Overall rating: 3/5 |
Method: Lemon is supposedly one of the best natural cleaners around because it is high in citric acid. Plus, it smells great. First, squeeze half of a lemon (about a tablespoon of lemon juice) into a bowl and add half a cup of water. Then microwaved it for two minutes and let the steam stay in the interior for another two. When the time is up, use a sponge (both the soft side and the scrubby side) to clean the splatters.
How it went: The splatters came off, and it seemed like they were loosened by the steam. But you have to do a good deal of scrubbing with the more abrasive side of the sponge. You also would not love using half of a lemon and wasting the other half. So, you can use the remaining part in your cooking. (If you have your own lemon tree, though, this might be a convenient and cost-effective method.)
How to Clean the Oven with Vinegar and Steam?
| Cleaning time: 6 minutes | Ease of use: 4/5 | Performance: 3/5 | Overall rating: 4/5 |
Method: Vinegar is one of the most efficient natural cleaners because its acidity helps cut through grease and loosen stubborn grime. To try this method, add one tablespoon of white vinegar to a microwave-safe bowl with half a cup of water. Microwave the bowl for two minutes, then leave the door closed for another two minutes so the steam can soften dried-on food and grease. Once the time is up, carefully get rid of the bowl and clean the interior with a sponge, using the scrubby side where needed to remove any remaining splatters or stains.
How It Went: You will likely appreciate how much easier it is to pour vinegar into a bowl compared to cutting and squeezing a lemon. It is definitely a more budget-friendly option. The vinegar steam cleaned slightly better than the lemon method, but compared to the other techniques below, it still fell a little short. You may still need to do some scrubbing to remove all the splatters.
How to Clean Inside of a Microwave with Dish Soap?
| Cleaning time: 5 minutes | Ease of use: 4.5/5 | Performance: 5/5 | Overall rating: 5/5 |
Method: Add a few drops of dish soap to a microwave bowl and pour in ½ to 1 cup of water. Place the bowl inside and heat on high for 2 minutes, or until the water creates a rolling steam. Leave the stove door closed for another 2 minutes. This allows the steam to fully saturate and loosen the grime. Carefully remove the bowl using oven mitts, and swab the interior walls, ceiling, and turntable with your sponge.
How it went: This method proved to be incredibly effective and powerful. Stubborn sauce splatters and grease came off with virtually no effort, making it one of the easiest cleaning techniques. The extra minute spent preparing the soapy solution saves significant time and heavy scrubbing later. It is a highly recommended go-to for future deep cleans.
How to Clean the Inside of a Microwave with Baking Soda?
| Cleaning time: 6 minutes | Ease of use: 4/5 | Performance: 3/5 | Overall rating: 4/5 |
Method: Baking soda is a popular natural cleaner that helps absorb odors and loosen stubborn food splatters. To try this method, mix 2 tablespoons of baking soda with 1 cup of water in a microwave-safe container and stir well. Microwave the mixture on high for 3 minutes, then leave the door closed for another 5 minutes. So, the steam can soften dried-on messes. Carefully remove the bowl and wipe the inside of the microwave with a clean cloth. Wash the turntable in warm, soapy water, then wipe the outside of the microwave door and handle before drying everything with a clean cloth.
How it went: The steam did a great job of loosening dried food and helping remove unpleasant odors. Most of the splatters wiped away easily, although a few headstrong spots still needed a little extra rubbing. Overall, this method left the microwave looking fresh and smelling clean without using harsh chemicals, making it a simple and budget-friendly cleaning option.
What are The Mistakes You Should Avoid During Microwave Cleaning?
- Skipping the ceiling. Food often splatters upward and dries where you can’t see it easily.
- Spraying cleaner directly inside. Always spray stainless steel-safe cleaning spray or any cleaner onto your cloth to avoid liquid getting into vents.
- Using abrasive scrubbers. These can scratch the interior finish, making it harder to clean in the future. Damage around the gasket can affect the microwave’s ability to close properly.
Tips: How to Keep Your Microwave Clean
The answer depends on how often you use it and how careful you are with food covers. Here’s a simple schedule:
1. Quick Wipe After Spills (Immediately)
If you notice a spill, splatter, or food boil-over, clean it right away. The longer it sits, the more difficult it will be to clean and the more likely it is to attract bacteria or cause odors.
2. Light Clean
Even if there aren’t visible messes, give the inside a quick wipe weekly. This prevents buildup and keeps smells from developing.
3. Deep Clean
Once a month, remove the turntable plate, clean all surfaces thoroughly, and check the exterior (especially the control panel and handle) for fingerprints, grease, and germs.
How Often Should You Clean Your Microwave?
Keeping an oven clean does not require harsh chemicals or complicated methods. A simple weekly routine helps prevent stains, odors, and food buildup. A deeper monthly clean keeps every corner fresh and hygienic. Following both routines can extend the life of the appliance and make everyday cooking more pleasant.
For Weekly Light Cleaning:
- Unplug the toaster oven (optional but safest).
- Remove the turntable plate and wash it in warm, soapy water.
- Spray glass cleaner lightly on a reusable cloth or sponge, never directly into the vents.
- Wipe the interior walls, top, and bottom of the oven.
- Dry with a duster before replacing the plate.
For monthly deep clean:
- Steam first for easier cleaning. Fill a microwave-safe container with water and a splash of lemon juice or vinegar. Heat for 2–3 minutes until steam forms. Let it sit for a minute before carefully removing the bowl.
- Wipe away loosened grime with a damp reusable cloth.
- Spray cleaner on your cloth and clean every surface, including the door gasket and control panel.
- For stubborn spots, sprinkle the cleaner directly onto the spot, let it sit for 1–2 minutes, then wipe.
- Clean the exterior – don’t forget the handle, as it’s a high-touch area.
- Replace the clean, dry turntable and plug the microwave back in.
