How to Clean Microwave
The bowl will be extremely hot after microwaving. Use oven mitts to remove it.
What You'll Need
- 1 lemon or 2 tbsp vinegar
- 1
- 1 cup
- 1
Step-by-Step Method
Fill a microwave-safe bowl with 1 cup of water. Add 2 tablespoons of white vinegar OR the juice of one lemon (drop the lemon halves in too). The acid helps break down grease.
Place the bowl in the microwave and run on high for 5 minutes. The water will boil and create steam that loosens all the baked-on splatter. Do not open the door when it finishes.
Keep the door closed for 3 minutes after the cycle ends. The trapped steam continues softening stuck-on food. This is the step most people skip, and it makes all the difference.
Carefully remove the bowl (it will be hot). Remove the turntable and wash it in the sink. Wipe all interior surfaces with a damp cloth. Everything should come off with almost zero effort.
- Do not use metal scrapers or abrasive scouring pads inside the microwave
- Do not run the microwave empty (damages the magnetron)
- Do not use commercial oven cleaner inside a microwave
- Cover food with a microwave-safe lid or damp paper towel to prevent future splatter
- Wipe up spills immediately after they happen. Fresh splatter takes 10 seconds to clean. Baked-on splatter takes 10 minutes.
- For persistent odors, leave an open box of baking soda inside overnight
Frequently Asked Questions

Yes. This method works on all standard microwave types including countertop, over-the-range, and built-in models.
Sources & Methodology
Steam cleaning exploits the principle that heated water vapor penetrates and rehydrates dried food residue, making it easy to wipe away. Acidic additives (vinegar or citric acid from lemon) accelerate grease breakdown.
