How to Clean a Microwave Inside: Easy Tricks to Make It Shine

The microwave is one of the most-used appliances in any kitchen. From reheating coffee to defrosting dinner or popping corn, it works hard—and splashes, grease, and odors soon take over. The good news: you don’t need harsh chemicals or hours of scrubbing to bring back the shine. Learning how to clean a microwave inside is surprisingly quick and easy.

This guide shows the most effective home remedies—using ingredients you already have in your pantry—to make your microwave look like new.

Star Trick: Steam Clean with Lemon or Vinegar

This is the most popular and effective way to loosen stuck-on grime with zero elbow grease. Let steam do the heavy lifting.

• What you need: A microwave-safe bowl, water, a lemon or white vinegar, and a cloth or sponge.

Steps

1. Mix the solution: Half-fill the bowl with water. If using lemon, cut it in half, squeeze the juice into the water, and drop both halves in. If using vinegar, add a generous splash (about 3–4 tablespoons).
2. Heat on high: Place the bowl in the center of the turntable. Heat on high for 3–5 minutes, until the water boils and the microwave fills with steam.
3. Let steam work: Key step! Don’t open the door when it stops. Leave the bowl inside with the door closed for 5–10 extra minutes so the trapped steam loosens grease and dried-on food.
4. Wipe effortlessly: Carefully remove the hot bowl. With a microfiber cloth or sponge, wipe the walls, ceiling, floor, and door—the grime should come off in one pass.
5. Don’t forget the turntable: Remove the plate and wash it in the sink like any other dish. Dry well before replacing.

Stubborn Stains or Burnt Spots? Use Baking Soda

If some marks remain after steaming, baking soda is your best ally.

• Make a paste: Mix a couple of tablespoons of baking soda with a little water until thick.
• Apply and wait: Spread directly over burnt or stubborn areas. Let sit for at least 15 minutes.
• Gently scrub: Rub with a damp cloth or non-abrasive sponge—baking soda is a mild abrasive that won’t scratch.
• Rinse and dry: Remove residue with a clean damp cloth and dry the interior thoroughly.

Microwaves are powerful tools. Even though we’re cleaning them here, remember their limits and avoid dangerous practices. For example, never attempt drying clothes in the microwave, as it can cause a fire.

How to Clean the Exterior & Remove Bad Odors

• Exterior cleaning: Wipe the outside with a damp cloth and a little all-purpose cleaner or soapy water. For stainless steel, use a dedicated cleaner and wipe with the grain to avoid streaks.
• Goodbye odors: If a smell lingers (burnt popcorn, for instance), leave a container with used coffee grounds or a small bowl of baking soda inside the microwave overnight with the door closed to absorb odors.
