Why Does the Inside of My Microwave Keep Bubbling and Peeling? The Real Reason Behind This Annoying Problem (And How to Fix It) 🥣⚡

Tomato sauce.

Vinegar-based marinades.

Citrus juices.

Wine reductions.

These acidic foods left in the microwave after heating begin to eat into the enamel — especially if they drip onto the floor or sides.

Eventually, those spots weaken — and peel.

✅ Pro Tip: Wipe spills immediately while still warm — it takes seconds and saves hours of scraping later.

⚠️ And There’s One More Sneaky Saboteur: The Turntable Wheel

Yes, even your microwave has a hidden troublemaker.

Underneath the glass turntable sits a plastic or rubber roller wheel. If food gets trapped underneath and isn’t cleaned regularly, the turntable grinds against the bottom — scratching and wearing away the enamel .

Over time?

That spot becomes thin, worn, and eventually peels — sometimes unnoticed until it’s too late.

✅ Fix: Remove the turntable weekly and wipe under the wheel. Just don’t forget to put it back — unless you want your mug of soup spinning all day long.

⚡ Is a Peeling Microwave Dangerous?

The short answer?

Sometimes.

Here’s the longer version:

Exposing metal beneath

Can cause arcing (sparks) during use

Arcing sparks

May damage internal components or start a fire

Rust forming on exposed metal

Could flake into food or reduce lifespan of appliance

Uneven cooking

Damaged surfaces reflect microwaves poorly

So while your microwave won’t explode (unless things really go wrong), a damaged interior can:

Shorten your microwave’s life

Ruin future meals with bits of rust or flakes

Become a safety issue if arcing begins

Not exactly appetizing.
