Pitting On Stainless Steel Pans

So, the other night, I made a beautiful filet mignon. I got the pan screaming hot, added a slick of oil, and dropped that steak in. The sizzle was music, the crust was forming, and I felt like a culinary god. Then I looked down and saw it: a constellation of tiny, dark pits spreading across the bottom of my beloved stainless steel pan. My heart sank faster than my sear.

That’s when I learned the harsh truth about stainless steel. It’s not invincible, even if it looks like it can survive a nuclear blast. Those little pits are the enemy, and they’re called pitting corrosion. Sounds fancy, right? It’s actually just chemistry being a jerk.

What the heck is pitting corrosion?

Think of it as the stainless steel equivalent of acne. But way more permanent. It happens when the protective layer of chromium oxide on your pan gets a tiny, microscopic break.

And what’s the number one culprit? Salt. That’s right, the most basic seasoning in your kitchen is a ticking time bomb for your pans. If you add salt to cold water, or—worse—sprinkle it directly onto a hot, dry pan, the salt ions gang up on that chromium layer. They create a little chemical battle that eats a tiny hole, and that hole is the pit.

The rookie mistakes (that I definitely made)

You know what I used to do? I’d boil pasta, dump the water, and leave the pan on the burner with salty water residue drying out. Classic amateur hour. That concentrated saltwater creates a perfect environment for pits to form.

And let’s not forget the “cook’s trick” of letting oil smoke. Super high heat is fine for searing, but if you leave an empty pan on high for too long, you can actually warp the metal and break down the protective oxide layer. The pan gets these rainbow-colored patches, which look cool but are actually a sign of weakness.

Side note: have you ever left a pan of tomato sauce simmering for hours? The acidity can also do a number on it. It won’t pit as fast as salt, but it will dull that mirror finish. Your pan ends up looking tired and abused. Just like me on a Monday morning.

How to spot the damage (before you cry)

Pitting doesn’t look like rust. It looks like tiny, dark craters or pinpricks. You might only see them when the pan is dry and you tilt it under the light. Run your finger over them—they feel rough and textured, like sandpaper.

The bad news: once a pit forms, it’s there forever. You can’t scrub it out. You can’t polish it away. It’s a scar. The good news? A few small pits won’t ruin your cooking. They’re just annoyances, like a scratch on your phone screen. You’ll still get a good sear.

The fix? Prevention, not cure.

Okay, here’s the real talk. How do you keep your stainless steel looking like a mirror and not a moonscape? First, never add salt to cold liquid. Wait until your water is boiling, then add the salt. The heat disperses it faster, so it doesn’t sit in a concentrated pile.

Second, don’t leave salty or acidic food in the pan to cool down. Clean it as soon as you’re done. I know, I know, you want to eat first. But your pan will thank you. Just rinse it with hot water and a soft sponge. No steel wool. Ever.

Third, if you burn something (and you will, we all do), don’t panic. Soak the pan with a little water and baking soda. Let it sit. Scrub gently. The goal is to remove the burnt gunk without scratching the protective layer.

The final sizzle

Look, stainless steel pans are workhorses. They’re not meant to be heirlooms you pass down for generations (unless you treat them like royalty). They’re tools. A little pitting is a badge of honor—it means you actually cook in that kitchen.

That filet mignon I made? It was perfect. The pan has a few pits now, and I see them every time I dry it. But you know what? I remember that meal. So don’t let the fear of a few tiny holes stop you from cranking up the heat and searing something delicious. Just maybe keep the salt away from the dry steel, okay? Your future self will thank you.
