How to Clean Microwave with Dish Soap

When to Use Dish Soap to Clean Your Microwave

While steam cleaning with vinegar or lemon is the easiest method for loosening baked-on residue, dish soap is the go-to for a direct, hands-on clean — especially for fresh splatters, greasy surfaces, and the turntable plate. Dish soap is a surfactant that breaks the bond between grease and surfaces, making it highly effective when combined with a little warm water and a good sponge. It's also the safest method for cleaning the microwave door seal and exterior.

What You'll Need

• Dish soap
• Warm water
• Microfiber cloth or non-scratch sponge
• Small bowl
• Old toothbrush (for the door seal)

A plant-based grease-cutting dish soap like Puracy Natural Dish Soap is gentle enough for microwave interiors while still cutting through grease effectively. Use microfiber cloths for wiping — they clean without scratching and leave no lint behind. A non-scratch scrub sponge handles any stubborn spots.

Step-by-Step: How to Clean a Microwave with Dish Soap

Step 1: Unplug or Turn Off the Microwave

For safety, unplug the microwave or ensure it's off before cleaning the interior with a wet cloth. This prevents accidental activation during cleaning.

Step 2: Remove the Turntable

Take out the glass turntable plate and the roller ring beneath it. Set aside for separate washing.

Step 3: Make Your Cleaning Solution

Mix a few drops of dish soap into a bowl of warm water. You want a sudsy solution — not overly soapy, as you'll need to rinse thoroughly afterward.

Step 4: Wipe Down the Interior

Dip a microfiber cloth or sponge into the soapy water, wring it out well, and wipe down the entire microwave interior — ceiling, walls, floor, and the inside of the door. Work from top to bottom so drips fall onto surfaces you haven't cleaned yet. For fresh splatters, this is usually all you need.

Step 5: Tackle Stubborn Spots

For dried-on or baked-on food, apply a small amount of undiluted dish soap directly to the spot. Let it sit for 2–3 minutes to penetrate the residue, then scrub with the sponge using circular motions. A toothbrush works well for corners and tight spots.

Step 6: Rinse Thoroughly

This step is critical. Rinse your cloth with clean water and wipe down the entire interior again to remove all soap residue. Soap left inside the microwave can produce an unpleasant smell when the microwave heats up. Repeat the rinse wipe 2–3 times until no soap remains.

Step 7: Dry the Interior

Wipe the interior dry with a clean dry cloth. Leave the door open for a few minutes to allow any remaining moisture to evaporate before closing.

Step 8: Wash the Turntable and Roller Ring

Wash the glass turntable plate and roller ring in the sink with warm soapy water. Rinse thoroughly and dry before replacing. The turntable can also go in the dishwasher if it's dishwasher-safe (check your microwave manual).

Step 9: Clean the Door Seal

Dip a toothbrush in the soapy water and gently scrub the door seal (the rubber gasket around the door opening). Wipe clean with a damp cloth and dry.

Step 10: Wipe the Exterior

Wipe the exterior of the microwave — top, sides, front panel, and handle — with a damp soapy cloth. Rinse with a clean damp cloth and dry. For stainless steel exteriors, wipe in the direction of the grain.

Dish Soap vs. Steam Cleaning: Which Should You Use?

• Dish soap: Best for fresh splatters, greasy surfaces, and targeted spot cleaning. Requires more manual wiping but gives you direct control.
• Steam cleaning: Best for baked-on residue and overall deodorizing. Less scrubbing required but needs a few minutes of wait time.
• Best approach: Steam clean first to loosen residue, then follow with a dish soap wipe-down for a thorough clean.

Tips to Keep Your Microwave Cleaner

• Use a microwave splatter cover every time you heat food — it prevents splatters from reaching the walls in the first place.
• Wipe up fresh splatters immediately after the microwave cools — they're dramatically easier to remove before they dry.
• Do a quick dish soap wipe-down weekly to prevent buildup.

Final Thoughts

Dish soap is a reliable, straightforward way to clean your microwave — especially for regular maintenance and fresh messes. The key is thorough rinsing to remove all soap residue. Combine it with a weekly steam clean and your microwave will stay spotless with minimal effort.
