How to look after a wooden chopping board
Most boards don't wear out — they dry out. Here's the five-minute routine that keeps a wooden board going for decades, the handful of things that genuinely ruin one, and how to bring a tired board back to life.
A board doesn't really wear out. In fifteen years at the bench I've had far more come back dried out, cracked, or smelling faintly of last week's onions than I've ever had worn thin from honest use. Wood is forgiving — it'll take decades of chopping — but it won't forgive being left wet, run through a dishwasher, or never once oiled. None of that is hard to avoid, and none of it costs anything. Here's what actually matters, and what doesn't.
Washing it
Warm water, a drop of washing-up liquid, a cloth or the soft side of a sponge. Wash it, rinse it, and — this is the bit nearly everyone skips — dry it straight off with a tea towel, then stand it on its edge so the air gets at both faces.
The thing that kills boards is water sitting on one side. A board left flat on a wet draining rack draws moisture into its underside and not its top; the two faces then move by different amounts, and that difference is your cupping and, in time, your cracks. Stand it up to dry. That one habit does more good than any oil.
Three things never to do:
- Don't put it in the dishwasher. Hours of hot water and heat will split even a well-made board — I've watched a cycle open a board straight down a glue line.
- Don't leave it soaking in the sink. Same reason, slower.
- Don't reach for the bleach. If you've cut raw chicken, a wipe with a cloth wrung out in hot water and a little white vinegar is plenty — wood is naturally hostile to bacteria in a way plastic isn't.
Oiling it
This is the five-minute job that keeps a board alive, and it's the one most people never get round to until the wood's gone grey and thirsty.
Use a food-safe oil — a proper cutting-board oil, or plain food-grade mineral oil from the chemist. Not olive oil and not vegetable oil: those turn rancid, and you'll know about it. Every board that leaves the workshop is finished in a food-safe oil already, so when yours starts looking dry you're only topping up what's there.
A board doesn't wear out. It dries out. Keep it fed and it'll outlast the kitchen it lives in.
How to do it
- Make sure the board is clean and properly dry.
- Pour a little oil straight onto the wood — more than you'd think; it drinks it.
- Work it in with a cloth or your bare hand, both faces and all four edges, going with the grain.
- Leave it overnight so it soaks right through.
- In the morning, wipe back anything that hasn't been taken up. That's the job done.
How often? When a board stops looking like wood and starts looking dull and pale, it's hungry — feed it. With everyday use that's roughly once a month at first, then less as the timber gets a good belly of oil into it. A board doing real work in a busy kitchen might want it monthly; one that mostly carries the cheese on a Sunday, twice a year is plenty.
Bringing a tired board back
If you've inherited a grey, rough, neglected board, don't bin it. Nine times out of ten it's perfectly good underneath. Give it a light sand with fine paper — 240 grit — to take off the fur, wipe away the dust, and oil it as above: two or three coats over a few days. It comes back darker and richer than you'd believe.
That's the quiet advantage of a solid wooden board over a sealed or laminated one — there's nothing to peel, so there's always something to bring back. An end-grain board like the Asterley is built that way through and through: solid timber, made to be revived rather than replaced.
That's genuinely the whole of it
Keep it out of standing water, dry it on its edge, and feed it oil when it's hungry. Do that and a board will see out the kitchen it lives in — which is rather the point of buying a real one in the first place.
If you're after a board built to take that kind of life, our end-grain boards are the hardest-wearing of the lot.
