Three habits, about five minutes a month. Do them and a solid board outlives the kitchen it sits in.
Wash by hand with warm water and a little soap, dry the board standing on its edge, and rub in a thin coat of food-safe oil about once a month. Never put it in the dishwasher, never let it soak. That's the whole routine — and it's the difference between a board that cracks in a year and one that lasts decades.
A solid wood cutting board is one of the few things in a kitchen that gets better the more you use it — if you treat it right. And "right" is almost nothing: a wash, a dry, and a wipe of oil now and then. Here's how, plus the handful of mistakes that quietly kill a board.
The monthly routine, step by step
- Wash by hand, right after use. Warm water, a drop of dish soap, a sponge. Rinse and move on. Don't let it sit in a sink full of water — that's the single fastest way to warp a board.
- Dry it upright. Wipe both faces, then stand the board on its edge so air reaches all sides evenly. A board left flat on a wet counter dries on one side only, and uneven drying is what cups and cracks it.
- Oil it about once a month. Wipe a thin coat of food-safe oil over the whole board — top, bottom, sides. Let it soak in for a few hours or overnight, then buff off whatever didn't absorb. The wood drinks it in and stays sealed against water.
- Refresh when needed. Garlic smell or a light stain? Scrub with coarse salt and half a lemon, rinse, dry, re-oil. Good as new in two minutes.
Which oil to use (and which to never use)
The job of the oil is to fill the wood so water can't. It has to be food-safe and it has to not go rancid, which rules out most of what's in your kitchen cupboard.
| Use | Avoid |
|---|---|
| Food-grade mineral oil | Olive oil — goes rancid |
| Fractionated coconut oil | Vegetable / sunflower oil — goes rancid |
| Board cream with beeswax | Cooking sprays |
One bottle of mineral oil lasts years, so don't overthink the brand. And there's a simple test for when to reach for it: flick a few drops of water onto the board. If they bead up, the seal is fine. If they soak in and the wood darkens, it's thirsty — oil it.
What if it already looks rough?
A dry, grey, or lightly scratched board is almost always recoverable. Scrub it clean, let it dry fully, then give it two or three coats of oil a few hours apart. The colour comes back and the surface re-seals. Deeper knife marks on a solid board can be sanded lightly with fine paper and then re-oiled — the wood is the same all the way through, so there's nothing to wear off.
That's the quiet advantage of solid wood over a coated or laminated board: it can always be brought back. We make ours from solid walnut, oak and maple in Kyiv and finish them with oil, not lacquer — so caring for them is exactly this, and nothing more.
Common questions
How often should I oil a wooden cutting board?
About once a month for normal use, more often if it starts looking dry or pale. If water stops beading on the surface, it's time.
What oil is safe to use?
Food-grade mineral oil or fractionated coconut oil. A beeswax board cream adds extra water resistance. Never use olive or vegetable oil — they turn rancid in the wood.
Can it go in the dishwasher?
No. The heat and long soak swell the wood and cause cracking and warping. Hand-wash only, and dry it upright.
How do I get rid of garlic or onion smell?
Scrub with coarse salt and half a lemon, rinse, dry, and re-oil. The salt lifts residue, the lemon neutralises the smell.
How do I stop it cracking?
Keep it oiled and never let it sit wet or soak. Cracks come from the wood drying and swelling repeatedly — a monthly oil and an upright dry prevents it.
