How to Clean a Microwave: The Ultimate Guide for Sparkling Results
Microwaves are one of the most-used appliances in any kitchen, so it’s no surprise they can quickly become a magnet for spills, splatters, and smells. Whether you’re dealing with dried-on food or just want to freshen things up. This guide will show you how to clean your microwave thoroughly, using only gentle, non-harsh chemicals.
Whether you have a built-in, combination, freestanding, or flatbed microwave, these simple methods will help you keep it spotless and odour-free.
How to Clean Your Microwave: Quick and Easy Methods
You don’t need specialised cleaning products to get great results. Most of the time, a few household items will do the trick.
1. Steam Cleaning (The Effortless Way)
This method is ideal for loosening dried-on food and tackling unpleasant smells.
What you'll need:
- Microwave-safe bowl
- 1 cup of water
- 1–2 tablespoons of white vinegar or lemon juice
- A few drops of essential oil (optional)
Steps:
- Add the water and vinegar or lemon juice to the bowl.
- Place in the microwave and heat on high for 5 minutes.
- Let it sit (door closed) for an additional 2–3 minutes.
- Carefully remove the bowl, then wipe down the interior with a cloth or sponge.
Tip: Drop a wooden toothpick into the bowl before heating to prevent superheating—an often-overlooked safety hack.
2. Baking Soda Paste for Stubborn Grime
If steam alone doesn’t do the job, try this natural scrub.
Steps:
- Mix 2 tablespoons of baking soda with a little water to form a paste.
- Apply it to stubborn stains.
- Leave for 5–10 minutes, then scrub gently.
- Wipe clean with a damp cloth.
Works especially well for flatbed models that can accumulate grime without a turntable.
3. Coffee Grounds to Neutralise Odours
Surprisingly effective—and it leaves a pleasant scent.
Steps:
- Add 2 tablespoons of used coffee grounds and half a cup of water to a microwave-safe bowl.
- Heat for 2–3 minutes.
- Leave the bowl inside (with the door closed) for up to an hour.
- Remove and wipe down the interior.
4. Don’t Forget the Door and Exterior
Even if the inside is spotless, the outside can collect grease and fingerprints.
Steps:
- Mix equal parts white vinegar and water in a spray bottle.
- Spray onto the door, handle, and control panel.
- Wipe with a microfibre cloth and dry with a paper towel to prevent streaks.
Why You Should Clean Your Microwave Regularly
Keeping your microwave clean isn’t just about appearances. Here's why it matters:
- Better hygiene – Leftover food residue can harbour bacteria and mould.
- Improved performance – A clean microwave heats food more evenly and efficiently.
- Prolonged lifespan – Regular maintenance helps protect components, especially for advanced models like Combination Microwaves.
Extra Tips for Ongoing Freshness
- Absorb Odours: Leave a small bowl of baking soda inside the microwave overnight.
- Prevent Splashes: Cover food with a microwave-safe lid or kitchen towel when heating.
- Quick Refresh: Heat a bowl of water with lemon slices for 2 minutes before wiping down.
A Note on Different Microwave Types
While these methods work for all models, a few things to keep in mind:
- Built-in models: Take care not to let moisture seep into any integrated cabinetry or control panels.
- Combination microwaves: Remove accessories and check for removable racks or trays that may need separate cleaning.
- Freestanding models: Unplug before cleaning to stay safe, especially when cleaning exterior surfaces.
- Flatbed models: Since they don’t have a turntable, spills tend to sit longer—clean them promptly to avoid baked-on messes.
Knowing how to clean a microwave doesn’t require special equipment—just a few clever tricks and everyday ingredients. A little regular attention can go a long way in keeping your microwave clean, safe, and efficient.
