How to Clean a Microwave: Effective and Natural Ways to Get the Job Done

Microwaves are one of the most used kitchen appliances in modern homes, yet they’re often one of the most neglected when it comes to cleaning. Whether you’re reheating leftovers or cooking meals, frequent use leads to inevitable spills and splatters, making the inside of the microwave a sticky, stained mess. Fortunately, you don’t need harsh chemicals to clean your microwave. With natural ingredients like lemon, vinegar, and baking soda, and by harnessing the power of steam, you can leave your microwave sparkling clean in just minutes.

In this guide, you’ll learn how to clean the inside of your microwave safely and effectively. From quick methods using household staples to deep-cleaning strategies for stubborn stains, we’ll cover everything you need to know to keep your microwave in top condition.

Why It’s Important to Clean Your Microwave

Over time, microwave splatter, spills, and stuck-on food debris build up inside your microwave, which can:

  • Produce unpleasant odors

  • Affect the flavor of your food

  • Harbor bacteria or mold

  • Reduce the efficiency of the appliance

Regular maintenance not only ensures hygiene but also prolongs the life of the microwave oven.

Best Ways to Clean a Microwave

There are many ways to clean a microwave, but the most effective methods use natural products and steam to loosen grime. Below are some tried-and-true techniques.

Use the Power of Steam and Lemon Juice

Why Lemon Works:

Lemon juice has natural antibacterial properties and a refreshing scent. Combined with the power of steam, it’s one of the best ways to clean your microwave without chemicals.

Instructions:

  1. Fill a microwave-safe bowl with 1 cup of water.

  2. Add the juice of one lemon (or a few slices).

  3. Place the bowl in the microwave.

  4. Run the microwave for 3 to 5 minutes on high power.

  5. Leave the door closed for another 2 minutes to let the steam loosen grime.

  6. Carefully remove the bowl (it will be hot).

  7. Wipe down the interior using a soft cloth, sponge, or paper towel.

This method is ideal for light to moderate cleaning and leaves a pleasant citrus smell.

Clean Your Microwave with Vinegar and Steam

Why Vinegar Works:

White vinegar is a natural disinfectant and odor neutralizer. It’s perfect for deep cleaning without damaging the microwave’s interior.

Instructions:

  1. Mix 1 cup water with 2 tablespoons of vinegar in a microwave-safe container.

  2. Microwave on high for 3–5 minutes, until the inside steams up.

  3. Leave the microwave door closed for a few minutes.

  4. Remove the bowl.

  5. Wipe down the microwave door, walls, and turntable.

Vinegar and steam are powerful allies against stuck-on food and microwave splatter.

Use Baking Soda to Scrub Away Stubborn Stains

If the inside of your microwave has tough spots or smells, baking soda is the answer.

Baking Soda Paste:

  1. Mix 2 tablespoons of baking soda with a bit of water to create a paste.

  2. Apply it to stuck-on food or stains.

  3. Let sit for 5–10 minutes.

  4. Scrub gently with a damp sponge or soft cloth.

  5. Rinse with soapy water and wipe down the interior.

Baking soda also absorbs odors, making your microwave clean and fresh.

Dish Soap and Water for Regular Cleaning

For everyday maintenance:

  1. Fill a microwave-safe bowl with soapy water (a few drops of mild dish soap in 1 cup of water).

  2. Heat for 2–3 minutes.

  3. Let the steam sit for a few more minutes.

  4. Remove the bowl.

  5. Use a damp cloth or sponge to clean the inside and microwave door.

This method is gentle yet effective for frequent wipe downs.

How to Clean the Microwave Turntable

Don’t forget the turntable, which catches a lot of food spills.

Instructions:

  1. Remove the turntable.

  2. Wash it in the sink with warm soapy water.

  3. Let it dry or wipe it dry with a soft cloth.

  4. Reinsert it after cleaning the rest of the microwave.

Deep Cleaning the Microwave Interior

Sometimes a dirty microwave needs more than just a quick wipe.

Step-by-Step Deep Clean:

  1. Unplug the appliance.

  2. Remove the turntable and any removable parts.

  3. Use the lemon and steam method (or vinegar).

  4. Apply baking soda paste to any remaining stuck-on areas.

  5. Use a sponge or soft cloth to scrub.

  6. Wipe all surfaces with a damp cloth.

  7. Dry thoroughly with a soft towel.

Make sure you check your microwave manual for any model-specific cleaning recommendations.
