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, leave it to soak for at least 20 minutes, then wipe off any excess so the surface feels dry, not greasy. Done regularly, this simple routine can help a quality board last 5 to 10 years or more.
Why oiling matters for wooden and bamboo boards
Wood and bamboo are naturally porous. Every time you wash your board, a little moisture leaves the fibres. If you never replace that moisture with oil, the surface starts to feel rough, small cracks appear and the board can warp or cup. Regular oiling solves three common problems in one go:
- Prevents cracking by keeping fibres flexible and less likely to split.
- Reduces staining and odours because oil fills the pores so juices from beetroot, onions or raw meat cannot soak in as easily.
- Improves hygiene since a well sealed board dries faster and is easier to clean.
At Deer & Oak, all of our boards, from the 45x35cm Carbonised Bamboo Board to the 38x28cm Medium Acacia Board, are pre oiled before they leave the workshop. That gives you a head start, but you still need to top up the protection every few weeks to keep them at their best.
Step by step: the best way to oil a wooden cutting board
Here is a clear, repeatable method you can use on any wooden or bamboo board, including the Deer & Oak range.
1. Clean and dry the board properly
- Wash the board with warm water and a small amount of mild washing up liquid.
- Scrub gently with a soft sponge or brush, paying attention to knife marks.
- Rinse and dry immediately with a clean towel.
- Stand the board upright and let it air dry for at least 2 to 3 hours, or overnight if it feels slightly damp.
Never oil a wet or even slightly damp board. Trapped moisture can lead to warping or dark patches.
2. Choose the right oil
For kitchen boards, the safest and most reliable choice is food safe mineral oil. It is colourless, odourless, and does not go rancid. You can also use a specialised board conditioner that blends mineral oil with natural waxes such as beeswax or carnauba wax for extra water resistance.
Avoid common cooking oils like olive, sunflower or rapeseed. These can turn sticky or develop an off smell after a few weeks.
3. Apply a measured amount of oil
As a guide, use about 1 to 2 teaspoons of oil for a medium board around 38x28cm, and 2 to 3 teaspoons for a larger 45x35cm board. More is not better. Thick layers just sit on the surface and feel greasy.
Place the board on a clean tea towel. Drizzle the oil directly onto the wood in a zigzag pattern.
4. Work the oil into the grain
- Use a lint free cloth, paper towel or your clean fingers.
- Rub in small circles, covering every part of the surface.
- Pay extra attention to the edges and any juice grooves, as these dry out fastest.
- Flip the board and repeat on the other side so both faces absorb oil evenly.
After 1 to 2 minutes of rubbing, the board should look evenly damp with no dry patches.
5. Let the oil soak for at least 20 minutes
Leave the board flat on the towel for 20 to 30 minutes. For a very dry or new board, you can leave it for up to 8 hours or overnight so the fibres absorb as much as they need.
If the surface looks dry again after 20 minutes, add another teaspoon of oil and repeat the rubbing step.
6. Wipe away every trace of excess
Once the soaking time is up, buff the board with a clean, dry cloth. Your goal is a satin finish that feels smooth and dry to the touch, not oily. Any oil that has not soaked in after 30 to 60 minutes is just sitting on top and will attract dust.
7. Stand the board to rest
Stand the board upright on its long edge and leave it in a well ventilated place for a few hours. After that, it is ready to go straight back into daily use.
How often should you oil a wooden cutting board?
For most home kitchens, oiling every 4 to 6 weeks is ideal. If you use your board several times a day, or you live in a very dry, centrally heated home, you may prefer every 2 to 3 weeks.
A simple test: sprinkle a teaspoon of water on the surface. If the droplets soak in within 10 seconds instead of beading on top, it is time to oil again.
Different woods, slightly different needs
Not all boards behave in the same way. Harder, denser woods can need slightly less frequent oiling, while lighter materials may benefit from a bit more care.
- Moso bamboo (as used in the Deer & Oak Large Bamboo Board and Bamboo Double Pack) is hard and naturally moisture resistant. Once a month is usually enough.
- Carbonised bamboo (used in the Carbonised Bamboo Board) is heat treated for a darker colour. It can be slightly more absorbent at first, so a little extra oiling during the first 3 to 6 months helps it settle.
- Acacia wood is naturally oily and dense. A board like the Large Acacia Board often stays happy with oiling every 6 to 8 weeks, unless your kitchen is very dry.

Who this is for (and who it is not for)
Ideal for:
- Home cooks who use a wooden or bamboo board at least 3 to 4 times a week and want it to last 5 to 10 years.
- People who care about the look of their kitchen and like the feel of natural materials.
- Anyone willing to spend 10 to 15 minutes once a month on basic board care.
- Those choosing quality boards such as the Deer & Oak Large Bamboo, Carbonised Bamboo or Acacia range and wanting to protect that investment.
Not recommended for:
- People who prefer completely maintenance free tools and never want to oil or hand wash their board.
- Commercial kitchens that run boards through dishwashers several times a day.
- Anyone with a strong preference for plastic boards that can be bleached and dishwashed aggressively.
- Those who regularly soak boards in water or leave them in the sink, as this shortens the life of any wooden board, even with oiling.
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 or a dedicated board conditioner that combines mineral oil with natural waxes. These products stay stable, do not go rancid and soak deeply into the fibres. Avoid standard cooking oils like olive or vegetable oil, as they can turn sticky and develop unpleasant smells.
Q: How often should I oil my cutting board?
A: For most home kitchens, oiling every 4 to 6 weeks keeps the board in good condition. If you use your board several times a day or live in a very dry home, you may prefer every 2 to 3 weeks. When water no longer beads on the surface and soaks in within a few seconds, it is time to oil.
Q: Can I use olive oil or other cooking oils on my board?
A: It is better not to. Olive oil, sunflower oil and similar cooking oils can oxidise over time, which makes the surface feel tacky and can produce a stale smell. Food safe mineral oil is specifically chosen because it stays clear, neutral and stable, even after months of use.
Q: Do I need to oil a brand new Deer & Oak board?
A: All Deer & Oak boards are pre oiled, so you can use them straight away. After about 4 weeks of regular use, check how quickly water soaks into the surface and apply a light oiling if the board looks dry or patchy. This first top up helps the board settle into your kitchen environment.
