The science behind cookware damage, plus 24 years of professional kitchen evidence. A 2022 study found that a single scratch on a nonstick pan releases up to 9,100 microplastic particles into your food.
After 24 years of professional kitchen experience—including 6 years at Purple Cafe where I trained dozens of line cooks on station work—I've watched more cookware get destroyed by metal utensils than by actual cooking. The scratched nonstick pans that stick. The cast iron skillets with gouged seasoning. The stainless steel pots with permanent scrape marks. Every single one was damaged by metal spoons, metal spatulas, or metal whisks that had no business touching that surface.
This isn't just about aesthetics. A 2022 study from the University of Newcastle found that a single scratch on a nonstick pan releases up to 9,100 microplastic particles into your food. A significantly damaged coating? Over 2 million particles per cooking session. That's not a theoretical concern—that's plastic in your dinner.
Here's what professional kitchens figured out decades ago: the right utensil protects your investment and keeps your food safer.
Nonstick cookware uses PTFE (polytetrafluoroethylene) coatings—the material you know as Teflon. This coating is softer than metal utensils. When a stainless steel spatula scrapes across the surface, it creates microscopic grooves that compromise the coating's integrity.
The Research:
Consumer Reports recommendation: "Avoid metal utensils. Try wooden or silicone instead." They also note that if your nonstick pan has any chips or scratches, it should be replaced—the coating could be flaking into your food.
Metal utensils don't just damage nonstick coatings:
Walk into any professional kitchen and you'll find wooden spoons in every station's mise en place. There's a reason this hasn't changed despite decades of new materials.
Heat Resistance: Wood doesn't conduct heat like metal. After 6 years at Purple Cafe, I never once burned my hand on a wooden spoon handle—even when it had been sitting in a 400°F saute pan. Metal utensils conduct heat straight to your fingers. Silicone can handle high heat, but wood remains cool to the touch throughout cooking.
Non-Reactive: Metal utensils can react with acidic ingredients, potentially adding metallic flavors to tomato sauces, citrus marinades, and wine reductions. Wood is completely non-reactive—it won't change the flavor of anything you're cooking.
Natural Durability: Quality hardwood utensils (maple, cherry, olive wood, beechwood) last for decades with minimal care. I still use wooden spoons from my first professional kitchen job. They've been through thousands of services and look better than they did new—wood develops a natural patina that actually improves with use.
Gentle on Surfaces: Wood is softer than metal but firm enough for effective cooking. It won't scratch seasoned cast iron, won't damage nonstick coatings, and won't leave marks on stainless steel.
There's ongoing debate about wood's sanitary properties. Here's what the research actually shows:
Wood has natural antibacterial properties. Studies have found that bacteria introduced to wooden cutting boards die off over time, while bacteria on plastic boards can survive in knife grooves. The same principle applies to wooden utensils—the wood's porous structure actually traps and kills bacteria rather than harboring it.
The caveat: This only works if you clean wooden utensils properly. Hand wash with hot soapy water, dry immediately, and never put them in the dishwasher (which causes cracking and warping).
Silicone utensils emerged as a modern alternative that combines wood's surface-safe properties with additional benefits:
Heat Resistance: Quality silicone handles temperatures up to 450-500°F without melting or warping. This exceeds most cooking temperatures and allows safe use with high-heat searing.
Flexibility: Silicone spatulas can scrape bowls completely clean—something rigid wooden spoons can't accomplish. For folding batters, scraping down sides, and transferring every last bit of sauce, silicone excels.
Non-Porous: Unlike wood, silicone doesn't absorb flavors, oils, or colors. Your silicone spatula won't taste like last week's curry or stain from tomato sauce.
Dishwasher Safe: For busy home kitchens, this matters. Silicone utensils can go through the dishwasher without degradation.
In my professional kitchen experience, we used silicone for:
We used wood for:
Professional Tip: For nonstick cookware like the Cuisinart 8-inch nonstick pan, silicone spatulas are ideal—they'll never damage the coating while still providing the control you need for delicate work like eggs and fish.
I'm not suggesting you throw away all your metal utensils. They have specific applications:
Stainless Steel Cookware: You can use metal on stainless steel without damaging the cooking surface—though you'll create visible scratches over time. For high-heat searing and deglazing, a metal fish spatula offers precision that silicone can't match.
Cast Iron (Carefully): A thin metal spatula can help scrape fond from cast iron when deglazing. Keep the angle shallow and avoid aggressive scraping. Some cooks prefer metal for flipping burgers on cast iron—the sharp edge slides under the crust better than silicone.
Professional Speed Work: In high-volume restaurant service, metal utensils offer speed advantages for certain tasks. But notice that professional kitchens also replace cookware more frequently than home cooks.
Never use metal utensils on:
The surface damage is permanent, accelerates coating degradation, and—in the case of nonstick—introduces microplastics into your food.

The choice between wood, silicone, and metal utensils isn't about preference—it's about protecting your cookware investment and your food safety.
A quality nonstick pan should last 3-5 years with proper care. Use metal utensils, and you'll be replacing it annually. That Le Creuset Dutch oven? One metal spoon can chip the enamel that's supposed to last a lifetime.
More importantly, the 2022 Newcastle research changed how we should think about scratched nonstick surfaces. Every scratch releases particles into your food. The solution is simple: wood and silicone for coated surfaces, metal only on stainless steel.
Professional kitchens figured this out decades ago. Your home kitchen deserves the same protection.
Yes, but carefully. Keep angles shallow to avoid scraping seasoning. Wood and silicone are gentler options that won't risk damaging the seasoning you've built.
Research shows wood actually has antibacterial properties—bacteria die off on wooden surfaces while surviving in plastic grooves. Hand wash thoroughly with hot soapy water and dry immediately.
Bamboo is harder than traditional hardwoods and may be more likely to scratch delicate surfaces. Stick with softer woods like maple, beechwood, or olive for coated cookware.
If you see visible scratches, the coating is flaking, or food starts sticking in specific areas, the pan should be replaced. Don't risk cooking with a damaged nonstick surface.
