If you want your wooden cutting board to last 5 to 10 years, you should oil it every 3 to 4 weeks using a food safe mineral oil, applying a thin coat for at least 20 minutes before wiping away the excess. That is the simple answer to how you oil a wooden cutting board: clean, dry, oil generously, let it soak, then buff.
Step by step: how do you oil a wooden cutting board?
Here is the exact method we recommend at Deer & Oak for all our boards, from a 38x28cm bamboo board to a 45x35cm acacia butcher style board.
-
Wash and dry the board
Wash the board with warm water and a small amount of mild washing up liquid. Scrub both sides and the edges. Rinse, then dry thoroughly with a clean tea towel. Stand it upright and let it air dry for at least 2 to 3 hours until the surface feels completely dry to the touch. -
Choose the right oil
Use a food safe mineral oil or a dedicated board oil. Avoid olive oil, vegetable oil or other cooking oils, as they can turn sticky and start to smell over time. For a typical 45x35cm board you will need around 10 to 15 ml of oil per coat. -
Apply a thin, even coat
Pour a small line of oil along the centre of the board. Use a lint free cloth, paper towel or a soft sponge to spread the oil over the whole surface, including the edges and any juice grooves. Work in small circles so the oil reaches every part of the grain. -
Let the oil soak in
Leave the board flat on a protected surface and allow the oil to soak in for 20 to 30 minutes. Very dry boards, or new boards, may need a second coat straight away. If the surface looks dry again after 20 minutes, add another light coat and repeat. -
Wipe off the excess
After the soaking time, use a clean cloth to wipe away any oil that has not soaked in. You want the surface to feel smooth but not greasy. This usually takes 1 to 2 minutes of firm buffing. -
Leave to cure
Stand the board upright and let it cure for at least 6 hours, or overnight if you can. This helps the oil settle properly into the fibres and reduces the chance of a tacky surface.
If you repeat this routine every 3 to 4 weeks, or whenever the board looks dry and pale, you can extend the life of a quality board to well over 8 years with normal home use.
How often should you oil different types of wooden boards?
Not all wooden boards behave in the same way. Bamboo, acacia and thick butcher style blocks each absorb and hold oil differently.
- Bamboo boards such as our Large Bamboo Board DNO-BCB-LG at 45x35cm usually need oiling every 3 to 4 weeks.
- Carbonised bamboo boards like the Carbonised Bamboo Board DNO-CBB-LG may feel slightly drier and benefit from oiling every 2 to 3 weeks in centrally heated homes.
- Acacia boards including the Large Acacia Board DNO-ACB-LG at 45x35cm often hold oil very well and can go 4 to 6 weeks between treatments if you are not soaking them in water.
- Heavy butcher blocks over 4cm thick can need 2 to 3 coats in one session when new, then monthly top ups.
As a simple rule, if water no longer beads on the surface and instead soaks in within 2 to 3 seconds, it is time to oil.
Choosing the right board to oil: size, weight and material
How you oil a wooden cutting board is the same across sizes, but the effort, oil quantity and drying time change with thickness and material. Below is a comparison of some Deer & Oak boards that home cooks often ask about when they are planning their care routine.
| Product | SKU | Size (L x W) | Weight | Material | Typical Oil Use per Session | Suggested Oiling Frequency | Price |
|---|---|---|---|---|---|---|---|
| Large Bamboo Board | DNO-BCB-LG | 45x35cm | 1.8kg | Moso Bamboo | 10 to 15 ml | Every 3 to 4 weeks | £34.99 |
| Medium Bamboo Board | DNO-BCB-MD | 38x28cm | 1.2kg | Moso Bamboo | 8 to 12 ml | Every 3 to 4 weeks | £24.99 |
| Carbonised Bamboo Board | DNO-CBB-LG | 45x35cm | 1.9kg | Carbonised Bamboo | 12 to 18 ml | Every 2 to 3 weeks | £39.99 |
| Large Acacia Board | DNO-ACB-LG | 45x35cm | 2.1kg | Acacia Wood | 12 to 18 ml | Every 4 to 6 weeks | £44.99 |
| Medium Acacia Board | DNO-ACB-MD | 38x28cm | 1.5kg | Acacia Wood | 8 to 12 ml | Every 4 to 6 weeks | £34.99 |
| Bamboo Double Pack | DNO-BCB-2PK | 45x35cm + 38x28cm | 3.0kg | Moso Bamboo | 18 to 25 ml (both boards) | Every 3 to 4 weeks | £49.99 |
Pre oiled boards, such as our Bamboo Double Pack on Amazon UK or the Carbonised Bamboo Board, still benefit from a maintenance coat every few weeks once they are in regular use.
Common problems and how oiling solves them
Oiling is not just about looks. It directly prevents some of the most frustrating problems people face with wooden boards.
-
Cracks and splits
Dry wood shrinks. Regular oiling keeps the fibres slightly flexible, which reduces the risk of hairline cracks, especially on larger 45x35cm boards where movement is greater. -
Warping
If one side of the board absorbs more water than the other, it can bow. A well oiled board repels water more evenly so you are less likely to see a 2 to 3mm lift at the corners. -
Stains and smells
Tomato, beetroot and raw meat juices can soak into dry wood. Oiled fibres resist deep staining, so most marks stay near the surface and lift off with normal washing. Smells from onion and garlic also cling less to a board that is regularly conditioned. -
Rough, raised grain
Water alone raises the grain, which makes the board feel rough. Oil flattens and fills those fibres so the surface stays smoother for longer and kinder to your knife edges.
If your board is already suffering from any of these, a simple cycle of light sanding with 240 grit paper followed by 2 to 3 oiling sessions, 24 hours apart, can often bring it back to life.
Who this is for
Ideal for...
Home cooks who prepare food daily on wooden or bamboo boards, anyone who has invested in a 45x35cm board and wants it to last at least 5 years, and people who prefer natural materials over plastic. It is also ideal if you own a Deer & Oak board such as the Large Bamboo Board DNO-BCB-LG, Medium Bamboo Board DNO-BCB-MD or Large Acacia Board DNO-ACB-LG and want a clear, simple care routine.
Not recommended for...
Those who want a completely maintenance free option, people who routinely put boards in the dishwasher, or commercial kitchens that need heavy duty plastic boards for very high volume prep and colour coded food safety systems. In those cases, wood care routines like this may feel like unnecessary effort.
Frequently asked questions
Q: What oil should I use on a wooden cutting board?
A: Use a food safe mineral oil or a dedicated cutting board oil that clearly states it is suitable for contact with food. Avoid cooking oils like olive, sunflower or rapeseed, as they can oxidise, turn sticky and develop off smells within a few weeks. If you want extra protection, you can finish with a thin coat of board wax after the oil has soaked in.
Q: How do I know when my board needs oiling again?
A: Run a teaspoon of water over the surface and watch what happens in the first 3 seconds. If the water beads up and stays on top, the board is still protected. If it soaks in quickly and darkens the wood, it is time to oil. Visually, a board that looks pale, patchy or feels slightly rough usually needs a fresh coat.
Q: Can I fix a warped or cracked cutting board with oil?
A: Light warping of 2 to 3mm can sometimes be improved by oiling both sides evenly and storing the board flat with a little weight on top for a few days. Cracks can often be stabilised by cleaning, letting the board dry fully for 24 hours, then giving 2 to 3 generous oil coats. Deep structural cracks may not fully close and might need professional repair or replacement.
Q: Is it safe to use a wooden board for raw meat if I oil it?
A: Yes, as long as you clean it properly and allow it to dry fully between uses. An oiled board is less likely to absorb juices deeply, which makes thorough cleaning easier. Many people keep one board, such as a 45x35cm bamboo board, for meat and another for bread and vegetables to keep routines simple.
