How to Clean Microwave After Explosion / Splatter

Why Food Explodes in the Microwave

Microwave explosions happen when steam builds up inside food faster than it can escape. Foods with skins (eggs, potatoes, grapes), sealed containers, and liquids heated too quickly are the most common culprits. The result is a spectacular mess — food splattered across every surface of the microwave interior. The good news: it looks worse than it is, and with the right approach it cleans up quickly.

Act Fast — Before It Dries

The single most important thing you can do is clean the splatter before it dries and hardens. Fresh food splatter wipes away in minutes. Dried, baked-on splatter can take significant scrubbing to remove. If you can't clean immediately, at least wipe up the bulk of the mess with a damp cloth right away.

What You'll Need

• Microwave-safe bowl
• White vinegar and water
• Dish soap
• Microfiber cloths and sponge
• Old toothbrush
• Rubber gloves (for messy explosions)

A steam clean with white vinegar and water is the fastest way to loosen dried splatter. Use microfiber cloths for wiping — they handle wet, sticky messes without scratching. A squirt of dish soap in warm water handles greasy splatter effectively. Going forward, a microwave splatter cover prevents this from ever happening again.

Step-by-Step: How to Clean a Microwave After an Explosion

Step 1: Let It Cool

Don't open the microwave immediately after an explosion — the interior will be very hot and steam may escape suddenly. Wait 1–2 minutes before opening the door carefully.

Step 2: Remove Large Debris

Use paper towels or a damp cloth to remove the bulk of the food splatter. Work from the ceiling down — top, walls, then floor. Don't worry about getting it perfectly clean at this stage; just remove the majority of the mess.

Step 3: Remove the Turntable

Take out the glass turntable plate and roller ring. These will be washed separately in the sink.

Step 4: Steam Clean to Loosen Dried Splatter

For any splatter that has already dried or is stuck to the walls, steam cleaning is the most effective solution. Fill a microwave-safe bowl with 1 cup of water and 1 cup of white vinegar. Microwave on high for 5 minutes. Leave the door closed for 3–5 minutes. The steam softens dried food splatter dramatically, making it easy to wipe away.

Step 5: Wipe Down the Interior

After steaming, wipe down the entire interior with a damp microfiber cloth — ceiling, walls, floor, and the inside of the door. Work from top to bottom. The steam will have loosened all remaining splatter. For any stubborn spots, apply a small amount of dish soap directly to the cloth and scrub gently.

Step 6: Clean the Ceiling

The ceiling of the microwave is often the hardest-hit surface in an explosion. After steaming, press a damp cloth against the ceiling and hold for a few seconds to let the moisture penetrate, then wipe in circular motions. A toothbrush helps with any textured ceiling surfaces.

Step 7: Clean the Door Interior

Wipe the interior of the door glass and the door frame thoroughly. Splatter reaches every surface, including the door. Use a toothbrush to clean the door seal folds where food residue hides.

Step 8: Wash the Turntable

Wash the glass turntable plate and roller ring in the sink with hot soapy water. Scrub thoroughly, rinse, and dry before replacing.

Step 9: Final Wipe and Odor Check

Do a final wipe of the entire interior with a clean damp cloth. If there's a lingering food odor, place a bowl of baking soda inside the closed microwave overnight to absorb it.

How to Prevent Microwave Explosions

• Use a splatter cover every time you heat food — it's the single most effective prevention measure.
• Pierce foods with skins before microwaving — potatoes, sausages, egg yolks, and similar foods need venting holes.
• Never microwave sealed containers — always leave a vent or remove the lid partially.
• Use lower power settings for liquids and foods prone to boiling over.
• Never microwave eggs in the shell — they will always explode.

Final Thoughts

A microwave explosion looks catastrophic but cleans up quickly with a steam clean and a thorough wipe-down. The key is acting before the splatter dries. And going forward, a microwave splatter cover costs just a few dollars and prevents the mess entirely — it's one of the best small investments you can make for your kitchen.
