If you want to know how to oil wooden cutting board properly, the simplest rule is this: apply a thin coat of food safe mineral oil every 3 to 4 weeks, or whenever your board looks dry, and let it soak for at least 20 minutes before wiping off the excess. Done regularly, this routine can help a quality board like the Deer & Oak Large Bamboo Board last 5 to 10 years of daily use.
Why you need to oil a wooden cutting board
Wood and bamboo are natural materials that slowly dry out. Without oil, they start to look grey, feel rough and can crack along the grain. Regular oiling keeps moisture out, stops liquids soaking in and helps your knife glide cleanly across the surface.
On a board around 45x35cm, like our Deer & Oak Large Bamboo Board at 1.8kg, a single treatment uses roughly 10 to 15ml of oil. That tiny amount can dramatically reduce staining from beetroot, curry and tomato, and it helps raw meat juices sit on the surface instead of seeping deep into the fibres.
What oil to use on a wooden cutting board
For any food board, you should only use a food safe, non drying oil that will not go rancid. The best options are:
- Food grade mineral oil often sold as cutting board oil. It is colourless, odourless and usually the most affordable option.
- Specialist board conditioners blends of mineral oil and beeswax or carnauba wax. These give extra water resistance and a soft sheen.
Avoid cooking oils like olive, sunflower or rapeseed. They can turn sticky, smell unpleasant and attract bacteria. For our pre oiled Deer & Oak chopping boards, we use food safe mineral oil and a light wax finish, which you can easily top up at home.
Step by step: how to oil wooden cutting board
This method works for bamboo and hardwood boards, including large butcher style blocks up to 5cm thick.
1. Clean and dry the board completely
- Wash the board with warm water and a small amount of mild washing up liquid.
- Scrub gently with a soft sponge or brush. Avoid soaking the board or leaving it in a sink of water.
- Rinse and dry thoroughly with a clean tea towel.
- Let it air dry standing upright for at least 2 to 3 hours, or overnight if it felt very wet.
Oiling a damp board traps moisture inside, which encourages warping and can shorten the life of the wood by several years.
2. Apply a measured amount of oil
- Pour about 10ml of oil onto the surface of a medium board around 38x28cm.
- For a larger 45x35cm board, use closer to 15ml to start.
- Use a lint free cloth, paper towel or a soft brush to spread the oil.
- Work in small circles, following the grain from one end to the other.
The surface should look evenly wet but not flooded. If small dry patches appear within a minute, add a few extra drops and blend them in.
3. Oil all sides and edges
- Flip the board and repeat on the other face.
- Do not forget the edges and any juice grooves or handles.
- For thicker butcher blocks, oil the sides as well as the top and bottom.
Edges are where cracks often start, especially on boards thicker than 2cm. A light coat of oil here can prevent those hairline splits that slowly creep across the surface.
4. Let it soak for at least 20 minutes
- Lay the board flat on a protected surface.
- Leave the oil to soak in for 20 to 30 minutes as a minimum.
- For very dry or new boards, leave it for up to 12 hours or overnight.
If the board is extremely thirsty, like a brand new acacia board or an older bamboo board that has never been oiled, you may need a second coat. After the first 30 minutes, if the surface looks completely dry, repeat the application with another 5 to 10ml.
5. Wipe off the excess
- Use a clean cloth or kitchen towel.
- Wipe firmly until the surface feels dry to the touch, not greasy.
- Stand the board upright and let it rest for another 2 to 3 hours before using.
Any visible puddles or sticky patches left on the board can collect dust and food particles, so it is important to remove them fully.
How often to oil wooden cutting board
Frequency depends on how often you cook and the type of wood.
- Daily use 3 to 5 times a day: oil roughly every 2 to 3 weeks.
- Regular use once a day: oil every 3 to 4 weeks.
- Occasional use a few times a week: oil every 6 to 8 weeks.
There are two simple tests:
- Water droplet test drip a teaspoon of water on the surface. If it beads up, the board is still protected. If it soaks in within 30 seconds, it is time to oil.
- Colour test if the board looks pale, chalky or grey, it needs fresh oil.
Our pre oiled XL bamboo chopping boards usually need their first top up after about 4 weeks of regular home use, then every month or so after that.
Extra protection: wax conditioning
Once your board is well saturated with oil, you can add a wax conditioner every 2 to 3 months for extra water resistance. This is especially helpful for heavy meat prep or busy family kitchens.
- Warm a small amount of conditioner between your fingers.
- Rub a very thin layer over the entire surface.
- Leave for 15 to 30 minutes.
- Buff with a soft cloth until it feels silky and dry.
Wax is particularly useful on darker boards like the Deer & Oak Carbonised Bamboo Board, as it helps maintain the rich tone and reduces light scratch marks from knives.
Choosing a board that responds well to oiling
Not all boards behave the same way when you oil them. Size, weight and material all affect how often you need to maintain them and how they feel in daily use.
| Product | SKU | Size (cm) | Weight | Material | Typical oiling frequency | Price |
|---|---|---|---|---|---|---|
| Large Bamboo Board | DNO-BCB-LG | 45x35 | 1.8kg | Moso Bamboo | Every 3 to 4 weeks | £34.99 |
| Medium Bamboo Board | DNO-BCB-MD | 38x28 | 1.2kg | Moso Bamboo | Every 4 to 6 weeks | £24.99 |
| Carbonised Bamboo Board | DNO-CBB-LG | 45x35 | 1.9kg | Carbonised Bamboo | Every 3 to 4 weeks | £39.99 |
| Large Acacia Board | DNO-ACB-LG | 45x35 | 2.1kg | Acacia Wood | Every 3 to 5 weeks | £44.99 |
| Medium Acacia Board | DNO-ACB-MD | 38x28 | 1.5kg | Acacia Wood | Every 4 to 6 weeks | £34.99 |
| Bamboo Double Pack | DNO-BCB-2PK | 45x35 + 38x28 | 3.0kg | Moso Bamboo | Every 3 to 5 weeks | £49.99 |
If you often cook for 4 or more people, a 45x35cm board gives enough space for full meal prep without crowding. If you mainly chop fruit, herbs and snacks, a 38x28cm board is easier to handle and store, and it uses slightly less oil each time.
Typical problems oiling solves
Regular oiling directly addresses some of the most common complaints people have about wooden boards:
- Board looks tired or grey a single oil treatment often restores the original tone in under 30 minutes.
- Strong smells linger oiled boards absorb less liquid, so onion and garlic odours do not cling as much.
- Surface feels rough oil swells the wood fibres slightly, making the board feel smoother under your knife.
- Small cracks forming timely oiling can slow or stop hairline cracks from spreading across the board.
For example, many customers who buy our Bamboo Double Pack use the larger board for meat and the smaller one for fruit and bread. Oiling both at the same time every 3 to 4 weeks keeps the meat board from staining deeply and helps the bread board stay smooth enough to use as a serving platter.
Who this is for
Ideal for
- Home cooks who use wooden or bamboo boards at least 3 times a week.
- People who want their cutting board to last 5 to 10 years rather than replacing it every 12 to 18 months.
- Anyone who uses quality boards like the Deer & Oak Large Acacia Board or Carbonised Bamboo Board and wants to keep them looking smart on the worktop.
- Those who prefer natural materials instead of plastic and do not mind a simple care routine once a month.
Not recommended for
- People who always put boards in the dishwasher and do not want to hand wash.
- Commercial kitchens that run at very high volume and need heavy duty plastic boards for colour coded food safety.
- Anyone who is unlikely to oil a board even every 2 to 3 months and prefers completely maintenance free tools.
- Very small kitchens where there is no room to dry or store a 45x35cm board upright.
FAQ
Q: How do I know when my wooden cutting board needs oiling?
A: Look for a dull, dry or slightly grey surface and do the water droplet test. If a teaspoon of water soaks in within about 30 seconds instead of beading on top, it is time to oil. Most home cooks find this happens every 3 to 6 weeks depending on how often they use the board.
Q: Can I use olive oil or other cooking oils on my board?
A: It is better not to. Oils like olive, sunflower or vegetable oil can go rancid, which leads to unpleasant smells and a sticky surface. Use a food grade mineral oil or a dedicated cutting board oil instead, then top up with a wax conditioner if you want extra protection.
Q: Do I need to sand my board before oiling it?
A: You usually do not need to sand a board that is only slightly dry. Just wash, dry fully and oil. If the surface feels very rough or has raised grain, you can lightly sand with fine 240 grit paper, wipe away the dust, then apply oil to restore a smooth finish.
Q: How long should I leave the oil on before wiping?
A: Aim for at least 20 to 30 minutes so the oil can soak into the fibres. For very dry or new boards, leaving it on for several hours or overnight works well. After that, always wipe away the excess so the surface feels dry, not greasy, before you start chopping again.
