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

If you’ve ever opened your microwave to find bubbling paint, peeling enamel, or weird chemical-looking burns on the walls…

You’re not alone.

I was scrolling through a homemaker group late at night (yes, insomnia), and saw a post that made me snort-laugh:

“This happens to every microwave I own. Am I cursed?”

Nope.

You're just dealing with one of the most common — and preventable — microwave mishaps out there.

Let’s break down why the inside of your microwave starts to look like it's shedding skin…

And how to stop it before sparks fly — literally.

🔍 What Causes the Inside of Your Microwave to Bubble and Peel?

It might seem random — but it’s usually due to one of three culprits:

1. Steam From Uncovered Food

When you heat up soups, sauces, or anything liquid-heavy without a cover, steam builds up fast — and blasts the inner walls and ceiling of your microwave.

Over time, this moisture eats away at the interior coating, causing:

Bubbling

Discoloration

Eventual peeling

✅ Fix: Always cover food with a microwave-safe lid or paper towel to contain splatter and steam.

2. Harsh Cleaning Products or Tools:

That steel wool you used to scrub off last week’s tomato sauce explosion?

Yeah… that wasn’t just cleaning.

That was slowly stripping away the protective layer inside your microwave.

Even abrasive cleaners like oven spray or bleach-based formulas can degrade the interior over time.

✅ Fix: Use gentle tools like soft sponges and natural cleaners (vinegar + water, lemon juice) to avoid wear and tear.

3. Acidic Food Left to Sit
