If you want your wooden cutting board to last 5 to 10 years, the best oil to use is food grade mineral oil applied in a thin coat every 4 to 6 weeks. For extra protection, many home cooks also add a board conditioner that combines mineral oil with natural waxes like beeswax.
Why the right oil matters for wooden cutting boards
Wood is porous. Without the right oil, it dries out, cracks and can absorb liquids from raw meat or juicy vegetables. Using a stable, food safe oil keeps the fibres hydrated, helps repel water and slows staining.
At Deer & Oak we pre oil every board, from our 45x35cm Large Bamboo Board to our 45x35cm Large Acacia Board, so they arrive ready to use. Keeping that finish topped up is simple once you know exactly what oil to reach for.
What oil for wooden cutting boards: the clear answer
For everyday care, use:
- Food grade mineral oil as your main treatment
- Optional wax conditioner with beeswax or carnauba wax for extra water resistance
Food grade mineral oil is colourless, odourless and does not go rancid. That last point is crucial. Many household oils start to smell and can even become sticky within weeks, which is the last thing you want on a 2.1kg acacia board that you slice bread and vegetables on every day.
Oils you should and shouldn’t use
Recommended oils
- Food grade mineral oil Also sold as cutting board oil or butcher block oil. Ideal for bamboo and hardwood boards. Penetrates deeply and stays stable for years.
- Board conditioner A mix of mineral oil and wax. Use every 2 to 3 months on high use boards like our 45x35cm Carbonised Bamboo Board to keep moisture out.
- Specialist wood oils labelled for food contact Some brands sell walnut or coconut based products that have been refined to stay stable. Always check the label for “food safe” and “non drying”.
Oils to avoid on cutting boards
- Olive oil, sunflower oil, vegetable oil These can turn rancid in as little as 30 to 60 days and leave strong smells.
- Sesame, peanut and other nut oils These also go rancid and can be an issue for anyone with allergies.
- Flaxseed and other drying oils Often used for furniture. They harden and can flake, which is not suitable for a food surface.
- Non food safe oils or varnishes Anything not clearly labelled for food contact should stay off your chopping board.
How often to oil wooden cutting boards
For most home kitchens, a simple schedule works well:
- New board Oil once a week for the first 3 weeks
- Regular use Oil every 4 to 6 weeks
- Heavy use Daily family cooking or a 3.0kg board set used for prep and serving may need oil every 2 to 3 weeks
If the surface looks pale, feels rough or absorbs water in under 10 seconds, it is time for oil, even if it has been less than a month.
Step by step: how to oil a wooden cutting board
- Clean first Wash the board with warm water and a small amount of mild washing up liquid. Rinse and dry thoroughly.
- Let it dry Stand it upright and leave for at least 12 hours so no moisture is trapped under the oil.
- Apply oil Pour about 1 to 2 teaspoons of food grade mineral oil onto a 38x28cm board, or 2 to 3 teaspoons for a 45x35cm board.
- Spread evenly Use a soft cloth or paper towel to work the oil across all sides, including edges and juice grooves.
- Let it soak Leave for 20 to 30 minutes. For very dry boards, leave overnight.
- Wipe off excess Buff with a clean cloth until the surface feels dry, not greasy.
- Optional wax coat Once or twice a season, finish with a thin layer of board conditioner, then buff after 15 minutes.
This routine suits every Deer & Oak board, from the 1.2kg Medium Bamboo Board to the 2.1kg Large Acacia Board. Pre oiled boards, like our Bamboo Double Pack on Amazon UK, only need topping up once the surface starts to look a little dry.
How oil works with different woods
Not all boards behave in the same way. Thickness, density and material all affect how much oil a board will drink in.
- Moso bamboo Used in our Large Bamboo Board and Medium Bamboo Board. Naturally dense and slightly more water resistant, so it often needs a little less oil. Once every 5 to 6 weeks is usually enough.
- Carbonised bamboo Like our 45x35cm Carbonised Bamboo Board. The heat treatment gives a deeper colour and can make the surface slightly more absorbent at first, so the first 2 or 3 oilings are particularly helpful.
- Acacia wood Used in our Large and Medium Acacia Boards. Acacia has a rich grain and benefits from regular oiling to keep that colour. Many customers notice the pattern deepen nicely after 2 to 3 treatments.

Who this advice is for
Ideal for
- Home cooks who use wooden or bamboo boards at least 3 times a week
- People who want their boards to last 5 to 10 years with simple, low cost care
- Owners of Deer & Oak boards looking for clear guidance that matches their exact product
- Anyone who prefers natural materials over plastic chopping boards
Not recommended for
- People who put boards in the dishwasher and do not want to hand wash or oil
- Commercial kitchens that need heavy duty plastic boards for strict colour coding
- Anyone sensitive to regular upkeep who prefers disposable or glass chopping surfaces
- Those who want a maintenance free worktop and never plan to oil wood surfaces
Common problems and how the right oil solves them
- Board feels rough or raised A dry 45x35cm board often develops a slightly fuzzy texture. One treatment with mineral oil, left overnight, usually smooths it out. Very rough spots may need a light sand with fine paper before oiling.
- Dark stains from beetroot or berries Oiling does not remove stains, but a well oiled board is less likely to absorb them in the first place. Keeping your board topped up every month acts as a barrier.
- Warping or slight twist This often comes from one side getting wetter than the other. After drying, oil both faces evenly so moisture is balanced. Our 1.8kg and 2.1kg boards are thick enough that regular oiling greatly reduces this risk.
- Lingering smells Garlic and onion can cling to dry wood. A light scrub with lemon and salt, followed by a fresh coat of mineral oil, usually clears the odour within 24 hours.
FAQ
Q: Can I use olive oil on my wooden cutting board?
A: It is not a good idea to use olive oil on a cutting board. Olive oil can turn rancid within a few weeks, which leads to unpleasant smells and a sticky surface. Food grade mineral oil stays stable and is much safer for long term use.
Q: How do I know when my board needs oiling?
A: If water no longer beads on the surface and instead soaks in within 10 seconds, it is time to re oil. You might also notice the colour looking dull or the surface feeling slightly rough. For most people this happens every 4 to 6 weeks.
Q: Do I need to oil both sides of the board?
A: Yes, you should always oil both sides and all edges. Treating just one face can cause uneven moisture levels, which increases the chance of warping. A thin, even coat on every surface keeps the board more stable.
Q: Is mineral oil safe for food contact?
A: Food grade mineral oil that is labelled for cutting boards or butcher blocks is safe for food contact. It does not contain additives or solvents and it will not go rancid. Always check the bottle states food grade before using it on your board.
