She kept buying new nonstick pans every couple of years. Same brand, same price, same slow slide from “eggs slide right off” to “everything sticks again.” She figured that’s just how nonstick works.
Then a friend pointed at her cabinet.
Her pans lived the way most of ours do. Big skillet on the bottom, medium pan tucked inside it, small one on top. A neat little tower under the counter. She never dropped them. She never used metal spoons or spatulas on them. She washed them by hand on low heat.
And the coating was still getting chewed up every single day, right there in the cabinet.
She didn’t know it yet, but she was doing one small thing every night that was slowly killing her cookware. Once she stopped, the next pan she bought stayed slick for years instead of months.
What the pan companies quietly admit in their own fine print
Before we get to what she was doing wrong, it helps to know this isn’t a random blog claim. The pan companies themselves put it in writing.
Consumer Reports interviewed cookware makers for its nonstick care guide, and Calphalon told them plainly: if you nest your pans, it can void the warranty they sold you. Read that again. The company that made your pan will refuse to replace it if you store it the same way almost everyone does.
It gets more specific. Made In, the cookware brand a lot of home cooks and chefs use now, says in its own care guide that you should always put a protector or clean towel between stacked pans. It says the same thing in its ceramic cookware guide. OXO, in its non-stick care guide, warns that if you skip that step, “over time the coating can break down and lose its effectiveness.”
Then Le Creuset, the maker of the enameled cast iron pots that cost hundreds of dollars (over €300), takes it a step further. Its official care and use instructions actually spell it out: to keep the outside, inside, and rim from getting scratched or chipped, always put a protector between pieces when you stack them for storage.
And this isn’t new. A US patent from the 1990s (number 5,988,385) was filed for a pan protector, and its opening lines read like a confession. The patent flat out says stacking frying pans on top of each other tends to damage their non-stick coatings, that the rough underside of the top pan scrapes the coating of the pan below, and that repeated stacking wears the coating off so food starts sticking.
The industry has known for almost thirty years. Most of us just never got the memo.
So what’s actually happening in there
The damage isn’t from cooking. It isn’t from washing. It’s from stacking your pans right inside each other with nothing between them.
Every time one pan sits directly inside another, three things start working against you.
The rim of the pan on top presses down in a full circle on the cooking surface below. That rim looks smooth, but up close it has tiny rough spots left over from how it was made. And the full weight of the pan is riding on that thin ring of your coating.
The bottom of that top pan sits on the cooking surface underneath. A lot of pans have slightly bumpy or ridged bottoms so they heat evenly. Cast iron bottoms are rougher. Every time you slide the top pan out to cook, that bottom drags across the coating like fine sandpaper.
And the stuff you can’t see makes it worse. Cooking oil, dust, and tiny crumbs settle everywhere in a kitchen. Once any of that gets trapped between two stacked pans, it acts like grit between two surfaces being rubbed together.
You never hear it happen. You never see the exact moment your pan got scratched. But if the wear on your pan is in a circle or an arc pattern that lines up with the rim of the pan you store on top, that’s your answer. The cabinet did it.
“Just being gentler when I stack them” doesn’t fix it either. The pressure is there whether you set the pan down softly or drop it in. It adds up over hundreds of little moves a year that you can’t even feel.
The fix takes two seconds and can cost nothing
You just need something soft between every pan. That’s the whole thing.
A soft layer takes the pressure off the coating so the metal rim and rough bottom never actually touch it. Every major pan brand agrees on this, and the stuff you can use ranges from free to about $8 (around €7).
Do this. Pick one and use it between every stacked pan:
- Paper towels, folded double. Free, already in your kitchen. Fold once so you get four layers, drop it in the pan, stack the next one on top. Swap them out every few months when they flatten or get grimy.
- Paper plates. Free if you have any. One per layer. Works great for big skillets since a full plate covers the whole cooking surface.
- A clean dish towel. Reusable and thick enough to fully cushion the rim. Can slide a bit under heavy pans, so tuck it in tight.
- Coffee filters. Cheap, thin, don’t shed lint, and gentle on delicate coatings. A good backup when you’re out of towels.
- Felt pan protectors. About $8 to $15 (roughly €7 to €14) for a set of six. Sized to fit standard pans, they don’t slip around, and they last for years. Le Creuset actually sells its own felt version and recommends it by name.
Skip these. They don’t actually help:
- A single sheet of paper. Too thin to do anything.
- Plastic bags. They slide, they trap moisture, and they can melt onto a coating if any pan goes back even a little warm.
- A lid stored upside down inside the pan. The lid rim still presses right on the coating, and you can chip the lid too.
One more thing that matters more than people think: make sure the pan is fully dry before you store it with a paper towel or felt pad in it. Trapped moisture will rust cast iron and can grow mildew on nonstick over time. Made In says this in its own care guide too. Wipe every pan out and let it air dry a few minutes before it goes back on the stack.
Two seconds a pan, and yours stop dying in the dark
That’s it. Drop a paper towel in. Set the next pan on top. Done.
The pans you already own won’t heal, but the damage stops the day you start. And the next pan you buy? This one small change is the difference between tossing it in a year and a half and still cooking on it in five.
The pan wasn’t the problem. The cabinet was.
