Microwaves get messy fast—food splatters, grease, and lingering odors can turn them into a sticky, smelly problem. Scrubbing with harsh chemicals isn’t the best idea, especially where you heat your food. That’s where steam cleaning comes in.
In this guide, you’ll learn how to steam clean a microwave quickly and safely using simple items you already have at home. I’ll also share my own tips, a few commercial steam cleaner options, and even how self-cleaning microwaves work.
What Is Steam Cleaning a Microwave?
When you steam clean, you heat water—sometimes with vinegar or lemon juice—until it creates steam that loosens stuck-on food and grease. No scrubbing, no elbow grease—just wipe it away.
Steam cleaning is safer for your microwave, faster, and far less messy than traditional scrubbing. It’s one of the best ways to steam clean a microwave without causing damage.

How to Use a Store-bought Microwave Steam Cleaner?
It depends on the brand you are using, check the instruction to use.
I can say for Angry Mama (as I tried it several times), just fill it with vinegar and water, pop it in the microwave, and heat. As it warms up, steam releases from the top, softening grease and stuck-on stains so you can wipe them away easily.
Best Microwave Steam Cleaners
In my opinion, Angry Mama is the most popular steam cleaner on Amazon. It comes in a lot of different colors and styles. It’s cheap, reusable, and works well, making it great for families that want things to be easy.
What About Self-Cleaning Microwaves?
New self-cleaning microwaves come with a feature with steam and built-in cycles to get rid of smells to make cleaning easier.
These microwaves automatically loosen food residue and get rid of smells with the push of a button, unlike manual steam cleaning. Self-cleaning models save time and effort, but manual steam cleaning is cheaper and works well in most kitchens.
They’re great for families with kids, people who are always on the go, or anyone who hates cleaning the microwave.
How to Steam Clean Self-Cleaning Microwaves?
In most self-cleaning or steam-clean microwaves (GE, Samsung, Whirlpool), you still need to place a bowl of water (sometimes with lemon or vinegar) manually.
Here’s how:
- Fill a Bowl with 1 cup water + a few lemon slices or 2 tbsp vinegar.
- Place in Microwave
- Run Steam Cycle – If your model (GE, Samsung, Whirlpool) has Steam Clean, press the button.
- Wait & Wipe – Let steam loosen grime, then wipe with a soft cloth.
- For Stubborn Spots – Repeat or use mild soap with a damp sponge.
Common Mistakes to Avoid When Steam Cleaning
- Opening the door too early – Don’t let the steam escape before it loosens the mess.
- Using the wrong bowl – Always use glass or microwave-safe, never metal.
- Overheating water – Super-hot steam can cause burns when you remove it.
- Skipping the wipe-down – Steam loosens grime, but you still need to wipe.
- Ignoring seals and vents – Dirt hides here and can cause odors later.
Tip: Reddit users recommend wiping the rubber or silicone seal (the gasket) after each cleaning. It keeps grease and food smells from sticking around.
