The best way to oil a wooden cutting board is to apply a thin, even coat of food safe mineral oil every 4 to 6 weeks, let it soak in for at least 20 minutes, then wipe off any excess so the surface feels dry, not greasy. Done regularly, this can extend your board’s life to 5 to 10 years or more.
Why oiling your wooden cutting board matters
Wood is naturally porous. Without oil, a board dries out, warps and starts to crack along the grain. Regular oiling fills those pores so water and food juices sit on the surface instead of soaking in. That means fewer stains, less odour and a board that stays flatter and smoother for years.
At Deer & Oak, all our boards, like the Large Bamboo Board DNO-BCB-LG, arrive pre oiled, but you’ll still want to top them up every few weeks, especially if you wash them daily or live in a dry, heated home.
Step by step: best way to oil a wooden cutting board
1. Choose the right oil
For kitchen boards, the safest and most reliable choice is:
- Food safe mineral oil (also called cutting board oil)
Avoid cooking oils like olive, sunflower or vegetable oil. They can turn sticky and rancid in 2 to 4 weeks and leave strong smells in the wood. If you’d like extra protection, you can follow mineral oil with a board wax that is usually a mix of mineral oil and beeswax.
2. Clean and dry the board first
Before you oil, the board must be completely clean and dry or you’ll trap moisture inside.
- Wash both sides with warm water and a tiny amount of washing up liquid
- Rinse well and towel dry straight away
- Leave the board to air dry upright for at least 3 to 4 hours, or overnight if it was very wet
Never soak your board in the sink and never put it in a dishwasher. High heat and standing water can warp even a 2.1 kg acacia board within a few cycles.
3. Apply a measured amount of oil
For most home boards, you only need a small amount of oil:
- Medium board (around 38x28cm): 1 to 2 teaspoons
- Large board (around 45x35cm): 2 to 3 teaspoons
Pour the oil directly onto the surface in a zigzag or a few small puddles. Use a clean, lint free cloth or a piece of kitchen towel to spread it in circular motions, working with the grain. Remember to:
- Oil the top, bottom and all four edges
- Pay attention to knife marks and end grain, where oil soaks in fastest
The board should look slightly glossy but you should not see deep pools of oil sitting on top.
4. Let the oil soak in
Once the surface is evenly coated, leave the board to rest on a drying rack or propped against a wall.
- Minimum soak time: 20 minutes
- Better: 1 to 2 hours
- Deep treatment for very dry boards: leave overnight
If your board is very thirsty, like a brand new carbonised bamboo board, you may need a second coat. When the first layer has soaked in and the surface looks matte again, repeat the same amount of oil and soak time.
5. Wipe off any excess
After soaking, take a clean, dry cloth and buff both sides of the board. This step is essential. Any oil left sitting on the surface can become sticky and attract dust. When you have finished, the board should feel smooth and dry to the touch, with a gentle sheen, not slippery.
6. Let it rest before use
Leave the board standing upright for at least 2 to 3 hours after the final wipe, so any remaining oil can settle. For heavy use boards, such as our butcher’s block style options, we suggest leaving them overnight before cutting meat or vegetables again.
How often should you oil a wooden cutting board?
How often you oil depends on how often you use and wash your board:
- Daily use for family cooking: every 3 to 4 weeks
- Moderate use (a few times a week): every 4 to 6 weeks
- Occasional use or charcuterie boards: every 2 to 3 months
A simple test: splash a teaspoon of water on the board. If the water beads up for at least 30 seconds, the oiling is still doing its job. If it soaks in within a few seconds or dark patches appear, it is time to oil again.
Best oils and routines for different board materials
Different woods behave slightly differently, so it helps to match your care routine to the material.
Bamboo boards
Products like our Large Bamboo Board DNO-BCB-LG and Bamboo Double Pack DNO-BCB-2PK are made from dense Moso bamboo. Bamboo absorbs a bit less oil than acacia, so one coat every 4 to 6 weeks is usually enough. Because bamboo is slightly harder, regular oiling also helps protect your knives by keeping the surface smooth.
Carbonised bamboo boards
Carbonised bamboo, as used in the Carbonised Bamboo Board DNO-CBB-LG, is gently heat treated to achieve its rich dark colour. This process opens up the fibres slightly, so these boards can be a little more absorbent. In the first 3 months, we suggest oiling every 3 to 4 weeks, then moving to every 4 to 6 weeks once the board is nicely seasoned.
Acacia boards
Acacia boards, such as the Large Acacia Board DNO-ACB-LG, are naturally rich in oils but still benefit from top ups. A 2.1 kg acacia board with a 45x35 cm surface area usually needs 2 to 3 teaspoons of oil per side. Because acacia has beautiful grain, oiling really brings out the colour and helps resist water marks from tomatoes, beetroot or citrus.

If you are choosing a board that will be simple to care for, it helps to know the exact size, weight and material. Heavier boards tend to stay flatter and feel more stable when you are chopping.

Common problems and how oiling helps
-
Problem: Board warping or rocking on the worktop
Cause: Moisture entering one side more than the other. Solution: Always oil both sides and all edges. Store your board upright so air can circulate evenly. -
Problem: Deep stains from beetroot, turmeric or meat juices
Cause: Dry, unsealed fibres soaking up pigment. Solution: Sand lightly with fine paper (240 grit), wipe clean, then apply 2 coats of mineral oil with at least 1 hour soak time each. -
Problem: Strong smells of onion or garlic
Cause: Odours trapped in pores. Solution: Scrub with half a lemon and coarse salt, rinse, dry overnight, then re oil. Oiling after cleaning helps prevent smells from sinking in next time. -
Problem: Board feels rough on the knife
Cause: Fibres raised by water and washing. Solution: Once the board is dry, sand very lightly with fine paper, wipe away dust and apply a fresh coat of oil.

FAQ
Q: What is the best oil to use on a wooden cutting board?
A: The best oil for a wooden cutting board is food safe mineral oil, sometimes sold as cutting board oil. It does not go rancid, has no strong smell and soaks into the wood evenly. For extra protection, you can finish with a board wax that combines mineral oil and beeswax.
Q: How long should I leave oil on a cutting board?
A: Leave the oil on your board for at least 20 minutes so it can soak into the fibres. For a deep treatment on a very dry board, 1 to 2 hours or even overnight is better. Always wipe off any excess so the surface feels dry before you use the board again.
Q: Can I use olive oil or vegetable oil on my wooden board?
A: It is not a good idea to use olive oil, vegetable oil or other cooking oils on a cutting board because they can turn sticky and rancid. This can give the board an unpleasant smell within a few weeks. Food safe mineral oil stays stable and is much easier to maintain over several years.
Q: How do I know when my cutting board needs oiling?
A: If the surface looks dry, feels rough or absorbs water instead of making it bead up, it is time to oil. You may also notice the colour looking faded compared to the edges or the underside. As a guide, most boards used daily benefit from oiling every 3 to 4 weeks.
