When someone places a cup (or bowl) of vinegar and water in the microwave and runs it, it’s not for cooking—it’s a simple trick to steam-clean the interior. Here’s why it’s genius:
🌬️ How & Why It Works
1. Creates soap-like steam
Heating vinegar/water generates steam that loosens dried-on food, grease, and splatters—making them easier to wipe away with just a cloth
2. Cuts through odors and bacteria
Vinegar’s acidity breaks down grime and deodorizes the microwave, helping remove lingering smells
3. Safe and non-toxic
Unlike harsh chemicals, vinegar is food-safe, eco-friendly, and won’t release toxic fumes inside the microwave
🔧 Reddit Wisdom
Real-life tips echo the method:
“Pro‑tip: do half vinegar, half water… steam melts the crud off so you can just wipe the inside”
“Place a shallow dish of vinegar… run it until it’s nice and steamy. Open and wipe out”
They also recommend letting it steam for a few minutes post-heating to let the loosened gunk settle before wiping
🧼 Step-by-Step
- Mix about 1 cup water with 1–2 tablespoons of distilled white vinegar.
- Microwave it on high until steam billows (2–5 minutes).
- Let it sit with the door closed for a few minutes.
- Carefully remove the bowl (use oven mitts).
- Wipe the interior with a soft cloth or sponge—no scrubbing needed!
📝 Quick Tips
- You can add lemon slices to improve the scent.
- Always use a microwave-safe container and avoid metal.
- Avoid overheated or straight vinegar—always dilute to prevent overly strong fumes.
✅ Final Take
Placing a vinegar-water cup in your microwave isn’t a gimmick—it’s a smart, chemical-free cleaning hack that softens grime, neutralizes odors, and leaves your appliance spotless with minimal effort.
