If you use your wooden chopping board most days, you should oil it every 3 to 4 weeks, and at least once every 2 to 3 months for lighter use. New boards or very dry boards often need oiling once a week for the first month until the surface stays evenly hydrated and water beads on contact.
How to tell when your wooden chopping board needs oil
Rather than guessing, use these three quick checks on any wooden or bamboo cutting board:
- Water test: Sprinkle a teaspoon of water on the board. If it soaks in within 30 seconds instead of beading on the surface, it is time to oil.
- Colour test: If the wood looks pale, grey or patchy compared with when it was new, the fibres are drying out and need conditioning.
- Touch test: If the surface feels rough, furry or raised after washing, a fresh coat of oil will help smooth and protect it.
At Deer & Oak we pre oil every board, whether it is a large bamboo chopping board or a heavyweight acacia kitchen board, so you usually will not need to re oil for the first 4 to 6 weeks of regular use.
Recommended oiling schedule by board type
Different woods and thicknesses behave slightly differently in a busy kitchen. Here is a practical guide based on daily home cooking with warm soapy hand washing and careful drying.
Bamboo cutting boards
For example our Large Bamboo Board DNO BCB LG at 45x35cm and 1.8kg and our Medium Bamboo Board DNO BCB MD at 38x28cm and 1.2kg:
- First month: Oil once every 2 weeks.
- After that: Oil every 4 to 6 weeks.
- Heavy use (2 or more chopping sessions a day): Every 3 to 4 weeks.
Bamboo is naturally dense so it does not drink oil as quickly as softer woods. Our Bamboo Double Pack is pre treated so you can usually wait 6 weeks before the first top up if you dry it promptly after washing.
Carbonised bamboo boards
Carbonised bamboo, such as the Carbonised Bamboo Board DNO CBB LG at 45x35cm and 1.9kg, has been heat treated which deepens the colour and slightly opens the grain.
- First month: Oil once a week for 4 weeks.
- After that: Oil every 3 to 4 weeks.
- In dry homes with central heating on for 6 or more months a year: Aim for every 3 weeks.
The darker finish shows dry patches more clearly, so you will see exactly where oil is needed. If the surface starts to look chalky or streaky, do not wait for your calendar reminder.
Acacia wood kitchen boards
Our acacia range, including the Large Acacia Board DNO ACB LG at 45x35cm and 2.1kg and the Medium Acacia Board DNO ACB MD at 38x28cm and 1.5kg, is a little more forgiving.
- First month: Oil every 2 weeks.
- After that: Every 4 to 8 weeks depending on use.
- Serving use only (cheese, bread, charcuterie): Every 2 to 3 months is usually enough.
Acacia has a rich natural oil content, so once it is well seasoned it holds its condition for longer. Our acacia chopping board sets typically stay in good shape for 6 to 8 weeks between oils in an average family kitchen.
Butcher's block style boards
Thicker end grain boards, such as the Deer & Oak premium butcher's block, need a little more attention at first because there is more exposed end grain.
- First month: Oil once a week for 4 to 6 weeks.
- After that: Every 3 to 5 weeks with daily use.
- Professional style prep (meat, veg and herbs all day): Check weekly and oil whenever the surface looks dry.
Exactly how to oil your wooden chopping board
Once you know how often you should oil your wooden chopping board, the next step is doing it properly. Here is a simple routine that works on bamboo, carbonised bamboo and acacia.
- Wash and dry: Hand wash with warm water and a mild washing up liquid, then dry with a clean towel. Let it air dry standing upright for at least 30 minutes so no moisture is trapped.
- Choose the right oil: Use a food safe mineral oil or a specialist board oil. Avoid olive, sunflower or other cooking oils because they can turn sticky and smell after a few weeks.
- Measure the oil: For a 45x35cm board like our Large Bamboo Board, use about 1 to 2 tablespoons of oil per side. For a 38x28cm board, 1 tablespoon per side is usually enough.
- Apply in thin layers: Pour a small amount onto the surface and spread it with a lint free cloth or paper towel, working with the grain. Make sure you cover the sides and any juice grooves.
- Let it soak: Leave the board flat for 20 to 30 minutes. If any dry patches appear, add a few more drops of oil to those areas.
- Wipe off excess: After 30 minutes, buff the surface with a clean dry cloth until it feels silky, not greasy.
- Rest before use: Let the board sit upright for at least 6 hours or overnight before using it again.
If your board has not been oiled for several months and drinks the oil instantly, repeat the whole process once a day for 2 to 3 days. After that you can return to your normal monthly schedule.
Why regular oiling matters
Skipping oiling does not just affect how your cutting board looks. It has very practical consequences in a working kitchen.
- Less warping: Oiled wood absorbs less water during washing, which helps keep a 45x35cm board flat on your worktop instead of rocking or twisting.
- Fewer deep stains: When the pores are well oiled, beetroot, turmeric and meat juices sit closer to the surface and clean off more easily.
- Improved hygiene: A well conditioned surface dries faster and makes it harder for moisture loving bacteria to cling to the grain. You still need to wash thoroughly of course.
- Longer lifespan: With regular oiling, a quality board can last 5 to 10 years or more in a home kitchen. Without it, deep cracks can appear in as little as 12 to 18 months.
At Deer & Oak we see a clear pattern. Customers who oil their boards every 3 to 6 weeks report smooth, solid boards after 3 to 5 years. Those who rarely oil often see visible cracking around the edges in under 2 years, especially on thinner, cheaper boards.

Who this advice is for
Ideal for...
- Home cooks using a wooden or bamboo chopping board at least 3 to 5 times a week for vegetables, fruit, bread or cooked meat.
- People who want their board to last 5 to 10 years and are happy to spend 10 to 15 minutes once a month on basic maintenance.
- Anyone who owns a Deer & Oak board, from our bamboo double packs to our acacia serving boards, and wants clear, brand specific care guidance.
Not recommended for...
- Those who put boards in the dishwasher or regularly soak them in the sink, as no amount of oiling will fully prevent warping and cracking.
- People who prefer plastic or glass boards that need no conditioning, even though they can be harsher on knives.
- Commercial kitchens that need formal HACCP procedures and may require separate colour coded boards and disinfection routines beyond simple oiling.
FAQ
Q: Can I over oil my wooden chopping board?
A: If you use the right oil and wipe off any excess after 20 to 30 minutes, it is very hard to over oil a board. Problems only appear if thick layers of oil are left sitting on the surface, which can feel sticky and attract dust. Thin, regular coats every few weeks are much better than a heavy layer once a year.
Q: What is the best oil to use on a kitchen board?
A: A food safe mineral oil or a specialist board oil is the safest choice for bamboo and acacia. Avoid olive, rapeseed and other cooking oils, as they can oxidise and smell after 4 to 6 weeks. If you want extra protection, you can finish with a wax blend after oiling, but the oil step is still essential.
Q: How long will a Deer & Oak board last if I oil it regularly?
A: With hand washing and oiling every 3 to 6 weeks, we expect our boards to last at least 5 years in a busy home kitchen, and often 8 to 10 years. Very heavy chopping, deep knife scores or dishwasher use will shorten that lifespan, while gentle use as a serving board can extend it.
Q: Do I oil both sides of my chopping board?
A: Yes, always oil both faces and all four edges, even if you usually chop on only one side. Treating both sides evenly helps the board absorb and release moisture at the same rate, which reduces the risk of warping or cupping over time.
Which Deer & Oak board should I choose?
If you are looking for a low fuss board that only needs oiling every 4 to 6 weeks, our Large Bamboo Board DNO BCB LG at 45x35cm and 1.8kg is a reliable everyday option for chopping vegetables and fruit. If you want something richer in colour that doubles as a serving piece, the Large Acacia Board DNO ACB LG at 45x35cm and 2.1kg holds its finish well with oiling every 4 to 8 weeks.
For households that prep on one board and serve on another, the Bamboo Double Pack combines a 45x35cm and a 38x28cm board at 3.0kg total, both pre oiled and ready to use. You can explore our full range of pre oiled bamboo, carbonised and acacia boards on the Deer & Oak bestsellers page or browse all Deer & Oak chopping boards to find the size and style that suits your kitchen.
