A microwave is one of the most-used appliances in any kitchen — but it's also one of the most overlooked when it comes to cleaning. If you’ve ever asked yourself, “How to clean my microwave properly?”, you’re definitely not alone.
From food splatters and grease to stubborn odors, a dirty microwave isn’t just unappealing — it can affect performance, harbor bacteria, and even become a fire risk. In this guide, AZParts shares the most effective tips on cleaning microwave interiors and exteriors, so you can keep your appliance in top shape for years to come.
Why You Should Clean Your Microwave Regularly
Many people assume microwaves don’t need cleaning because they heat food at high temperatures. But that’s a dangerous myth. According to a 2017 NSF International study, microwave keypads are among the most contaminated surfaces in your kitchen — more than sinks and cutting boards — often harboring bacteria like E. coli and Salmonella.
Here’s why regular cleaning matters:
- Prevents bacterial growth: Food residue is a breeding ground for germs.
- Eliminates lingering odors: Stuck-on particles cause bad smells that transfer to fresh meals.
- Improves heating efficiency: Greasy buildup can block heat and cause uneven cooking.
- Reduces fire hazards: The NFPA reports microwaves are responsible for 4% of cooking-related fires — often due to grease.
- Extends lifespan: A clean, well-maintained microwave can last 7–10 years vs. 5 or fewer if neglected.
How to Clean a Microwave
1. Quick & Easy Cleaning (For Light Messes)
If your microwave has minimal splatters or mild odors, this simple method will work effectively.
What you need:
- A damp sponge or microfiber cloth
- Mild dish soap
- Warm water
Steps:
- Unplug the microwave – Always disconnect the power before cleaning.
- Wipe down the interior – Use a damp sponge with warm, soapy water to clean the walls, ceiling, and turntable.
- Clean the turntable – Remove the glass tray and wash it separately with dish soap.
- Wipe the exterior – Clean the door, handle, and control panel with a damp cloth.
- Dry with a clean towel – Ensure all parts are completely dry before plugging the microwave back in.
Recommended Frequency: At least once a week to prevent buildup.
2. Steam Cleaning with Vinegar or Lemon (For Moderate Stains & Odors)
For stubborn stains and lingering odors, steam cleaning is the best solution.
What you need:
- 1 cup of water
- 2 tablespoons of white vinegar (or 1 sliced lemon)
- Microwave-safe bowl
- Sponge or cloth
Steps:
- Prepare the cleaning solution – Add 1 cup of water and 2 tablespoons of vinegar (or use sliced lemons) in a microwave-safe bowl.
- Microwave on high for 5 minutes – This creates steam that loosens dried-on food and grease.
- Let it sit for 2 minutes – Allow the steam to continue breaking down grime.
- Wipe down the interior – Use a sponge or cloth to remove softened debris.
- Clean the turntable & exterior – Wash the turntable separately and wipe the control panel with a damp cloth.
Recommended Frequency: Every 1-2 weeks to keep the microwave fresh and odor-free.
3. Deep Cleaning with Baking Soda (For Heavy Grease & Burnt Stains)
For tough stains, dried-on grease, or burnt food residue, a baking soda paste works best.
What you need:
- 3 tablespoons of baking soda
- Water (enough to form a thick paste)
- Sponge or scrub brush
Steps:
- Mix baking soda and water – Create a thick paste.
- Apply to stained areas – Focus on stubborn spots inside the microwave.
- Let sit for 5 minutes – This helps loosen grime.
- Scrub gently – Use a sponge or brush to remove stains.
- Wipe with a damp cloth – Clean off any residue and dry the microwave with a towel.
Recommended Frequency: Once a month or as needed for deep cleaning.
5 Maintenance Tips on Cleaning Microwave (and Keeping It Clean)
- Cover your food with a microwave-safe lid or paper towel to prevent splatters.
- Clean spills immediately to avoid them hardening.
- Never use metal or foil — it can cause sparks and fires.
- Check and clean vents/filters (especially for over-the-range microwaves).
- Wipe the door seal regularly to prevent leaks and maintain efficiency.
