Why Chefs Never Put Wooden Utensils in the Dishwasher

The dishwasher beeped; the door popped open; a rush of damp heat spilled across the kitchen.

Between the sparkling glasses and the plates that squeaked when you touched them, something looked… off. A wooden spoon that used to be smooth and honey-coloured now seemed flat and tired, with fine cracks and a handle that had subtly bent, as though it had aged a decade in a single wash. Its owner lifted it, frowned, then shrugged and dropped it back into the drawer. The following evening, it went through the dishwasher again. And again.

It’s a small, almost unconscious routine. Dirty wooden spoons, salad servers, chopping boards: straight into the rack, shut the door, press start. Quick, tidy, modern. But ask professional chefs how they feel about that and you’ll usually see the same response: a sharp wince, a slow shake of the head, sometimes a full “nooope”. They know precisely what those cycles do to wood - and their reasons aren’t just about looks.

What really happens to wooden utensils in your dishwasher

If you watch a chef clear down after a busy service, one detail stands out. Metal pans may be sent to the wash station without a second thought, but wooden spoons and boards almost never are. They get set aside, rinsed with care, towel-dried, then left to finish drying on a rack like small, valued tools. In professional kitchens, wood is treated more like skin than steel. It’s a living material, packed with pores, fibres and tiny channels you can’t see. Put it into the high-heat, high-pressure, detergent-soaked environment of a dishwasher and it doesn’t simply get “washed”. It gets battered, again and again.

Most home cooks only notice the consequences after weeks or months. Handles that were once straight start to twist. Edges that felt silky turn fuzzy and rough. Dark patches show up near joints - especially where a spoon’s handle meets its bowl, or around the end grain on a chopping board. And that’s just the visible part. Beneath the surface, water repeatedly forces its way in and out: the wood swells, then shrinks as it’s dried too quickly. Microscopic splits develop along the grain. Small gaps appear where food residue, soap and bacteria can lodge. It’s gradual damage - easy to miss until the day your favourite spoon suddenly snaps mid-stir while you’re making soup.

Chefs describe wood in the same practical way a carpenter would. Prolonged contact with hot water makes fibres expand, then the harsh heat of the drying cycle pulls them tight too fast. That movement, repeated dozens of times, weakens the structure. Strong detergents also strip the wood’s natural oils, much like an aggressive shampoo can leave hair brittle. Bare, thirsty wood then absorbs even more moisture on the next round and dries out more unevenly afterwards. The result is utensils that don’t just look worn, but can become less hygienic too. Those cracks and warps create perfect little hideaways for mould and lingering odours - and where food safety is non-negotiable, that’s a dealbreaker for most chefs.

How chefs actually wash and care for wooden utensils

Ask a chef the right way to clean a wooden spoon and the answer is almost disappointingly straightforward: warm water, mild washing-up liquid, and your hands. No special kit required. Rinse the spoon or board soon after using it, especially if it’s been in contact with raw meat, fish, eggs, or anything strongly acidic such as lemon or tomato. Then wash it as you would a favourite mug - gentle, but thorough. Rinse well, dry with a clean cloth, and leave it upright or on its side so air can circulate. The aim is not to soak the wood; it’s to clean the surface and let it dry calmly.

The same logic applies to chopping boards. In professional kitchens, a wooden board is rarely left sitting in a sink of water - soaking can be nearly as punishing as the dishwasher. Instead, cooks scrape off stuck-on bits, wash both sides quickly, then stand the board upright so it dries evenly. Some people scatter a little coarse salt and rub the surface with a cut lemon to lift stains and remove odours. It takes two minutes, smells fresh, and avoids harsh chemicals. Let’s be honest: nobody really does that every day. Still, doing it often enough can make a noticeable difference to how long your board stays in good condition.

Then there’s the step many home cooks miss: feeding the wood. Every few weeks, chefs work mineral oil or a dedicated board conditioner into their wooden tools. A soft cloth, a small amount of oil, slow circular motions, leave it to absorb, then wipe away what remains. It’s oddly calming - like shining shoes or winding a mechanical watch. The oil helps seal the pores and reduces the swell-and-shrink cycle. It won’t make wood waterproof, but it gives it a fighting chance against heat and humidity. That’s one of the real reasons those heirloom spoons can cope with decades of daily cooking without falling apart.

What chefs say, and how to make it work in real life

Professional cooks tend to be blunt about wood and dishwashers. Many run a hard rule: if it’s wooden, it doesn’t go anywhere near the machine. One chef compared it to putting leather shoes in a washing machine on a high-heat programme. Sure, they’ll come out “clean”. They’ll also come out damaged. Wooden salad servers, rolling pins, spatulas, pestles, chopsticks - even the wooden handles on certain knives - all take the same kind of hit: high temperatures, powerful detergents, and an unforgiving drying phase. It may feel convenient on a Tuesday night, but it quietly reduces the lifespan of anything made from wood.

At home, the boundary can be more flexible - and that’s realistic. There are exhausted evenings, piles of washing-up, children to wrangle, and a very real temptation to load everything into the dishwasher. On nights like that, a wooden spoon can feel insignificant. The real danger usually isn’t one cycle; it’s the pattern, repeated all year. A single shortcut won’t ruin the tool. Years of shortcuts will. So rather than aiming for perfection, many chefs suggest a practical compromise: choose your best wooden tools - the ones you’d genuinely miss - and give them the careful treatment. Keep the cheaper spare spoons as the ones you’re willing to risk when you absolutely have to.

“Every tool in my kitchen has a job,” explains London-based chef Marta Rossi. “If I respect it, it does that job better and for longer. Wood is alive. If you treat it like plastic, don’t be surprised when it behaves badly.”

Her method boils down to a few habits that won’t turn a weeknight into a ceremony. Begin with a quick sort: which wooden items are essential, which have sentimental value, and which are easily replaced. Keep the essentials out of the dishwasher. Hand-wash them fast, then dry them properly. Now and then, oil your main board and your go-to spoon. It’s ten minutes, perhaps once a month.

• Keep wooden utensils out of the dishwasher whenever you can.
• Wash with warm water and mild soap, then dry immediately.
• Stand boards upright so both faces dry at the same rate.
• Oil spoons and boards regularly to reduce cracking.
• For hygiene, replace wood that is deeply cracked or showing mould.

A different way of seeing what’s in your drawer

There’s a quiet satisfaction in holding a wooden spoon that’s been with you for years. The handle has darkened where your fingers naturally sit. The edge has worn into the exact curve of the pot you use most. These small, imperfect tools can carry recipes, memories - even whole chapters of your life. They deserve more than a rough blast of steam and chemicals. When chefs say “don’t put wood in the dishwasher”, they’re not just being fussy; they’re protecting the working life of tools they rely on every day.

We live surrounded by things designed to be replaced quickly: cheap spoons, thin boards, flimsy utensils that bend under minimal pressure. Treating wood as something worth maintaining is almost a small act of resistance. It’s choosing to keep something longer, to understand it, to let it mature instead of watching it crumble. The next time the dishwasher beeps and you’re holding a damp wooden spatula, you might pause for a moment. One small choice: rack, or sink.

And that tiny moment says plenty about how we cook, how we shop, and how we look after the objects that quietly support everyday life. Perhaps you’ll start with a single spoon - or one chopping board you decide to rescue from the machine. Over time, you’ll notice the difference in colour, texture, and even smell. You may even catch yourself telling a friend, almost like a secret: “Leave the wood out of the dishwasher. It’s worth it.”

FAQ:

• Can I ever put wooden utensils in the dishwasher “just this once”? One wash won’t instantly destroy them, but repeated cycles accelerate cracking, warping and splintering. Think of the dishwasher as a last resort, not a routine.
• What’s the safest way to clean wood after raw meat or eggs? Rinse promptly, wash with hot water and washing-up liquid, scrub thoroughly, then dry completely. For extra reassurance, you can wipe with white vinegar after washing.
• How often should I oil my wooden spoons and boards? Every 3–4 weeks if they’re used daily, or whenever the surface looks dry and rough rather than smooth and slightly silky.
• Which oil should I use on wooden utensils? Food-grade mineral oil or a dedicated chopping board oil is ideal. Avoid everyday cooking oils such as olive or sunflower, as they can become sticky and turn rancid.
• When should I throw away a wooden utensil? Replace it if there are deep cracks, black spots that won’t scrub away, soft or spongy areas, or a persistent unpleasant smell even after cleaning.
