If you want a wooden or bamboo chopping board to last 5 to 10 years instead of 1 to 2, then yes, chopping board oil is necessary. The best way to keep a 45x35cm kitchen board flat, food safe and looking smart is to oil it lightly every 3 to 4 weeks with a food safe mineral oil or board conditioner.
Why chopping board oil is necessary for wooden and bamboo boards
Wood and bamboo are natural materials that constantly take in and release moisture. Without oil, a cutting board dries out, the fibres lift and you start to see cracks, warping and deep stains. With regular oiling you slow that movement right down.
On a practical level, board oil helps in three clear ways:
- Prevents cracking and warping by keeping moisture levels more stable across the board
- Improves hygiene because a well oiled surface absorbs less raw meat juice, onion smell and food colouring
- Makes cleaning easier as food sticks less and wipes off faster
For a typical Deer & Oak 45x35cm board used daily, a 2 to 3 minute oiling every month can easily double or triple its working life.
When is chopping board oil truly necessary?
Oil is essential for any wooden, bamboo or acacia chopping board. That includes heavy butcher's blocks, lighter bamboo kitchen boards and serving boards used for bread and cheese.
You should absolutely be oiling if:
- Your board is made from acacia, bamboo, beech, oak or maple
- The surface feels rough or looks chalky and pale in places
- Water no longer beads on the surface but sinks in within 2 to 3 seconds
- You see hairline cracks, especially at the ends of the grain
Oil is not necessary for plastic, glass or marble boards. These materials do not absorb moisture in the same way, so oil will simply sit on the surface and feel greasy.
What type of chopping board oil should you use?
For kitchen use, the safest choice is a food grade mineral oil or a board conditioner that blends mineral oil with natural waxes such as beeswax or carnauba wax. These are stable, neutral and do not go rancid.
Avoid everyday cooking oils such as olive oil, vegetable oil or nut oils. They can oxidise, start to smell and leave sticky patches in as little as 3 to 6 months.
At Deer & Oak we pre oil our boards at the factory, including the Bamboo Double Pack chopping board set and the Carbonised Bamboo Board. That first treatment gives you a head start, but you should still top up at home every few weeks.
How to oil a chopping board in 5 simple steps
If you are wondering how to care for a kitchen board without spending ages on it, this simple routine works for most wooden and bamboo boards:
-
Wash and dry
Wash the board with warm water and a tiny amount of mild washing up liquid. Rinse, then dry thoroughly with a clean towel. Let it air dry upright for at least 2 hours until it feels completely dry. -
Apply oil
Pour about 1 to 2 teaspoons of food safe board oil onto the surface of 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 over the entire surface, including the sides and any juice groove. Always follow the grain. -
Let it soak
Leave the board lying flat for 20 to 30 minutes so the oil can soak in. Very dry boards may need a second light coat straight away. -
Wipe off excess
Buff the surface with a clean, dry cloth until it feels smooth and not sticky. The board is ready to use.
For heavy use, such as a butcher's block used daily for meat, repeat this routine every 2 to 3 weeks. For lighter use, once a month is usually enough.
How often should you oil different Deer & Oak boards?
Different materials hold oil differently. Here is a simple guide based on real sizes and weights from the Deer & Oak range:
- Moso bamboo boards such as the Large Bamboo Board 45x35cm, 1.8kg benefit from oiling every 3 to 4 weeks if used daily
- Carbonised bamboo boards like the Carbonised Bamboo Board 45x35cm, 1.9kg are slightly denser and can often go 4 to 6 weeks between oilings once well seasoned
- Acacia boards such as the Large Acacia Board 45x35cm, 2.1kg are naturally more oily and can be maintained every 4 to 6 weeks for normal home use
If you live in a very dry home, especially with central heating on for 6 or more months of the year, you may want to oil a little more often.

Product problems that chopping board oil solves
Oiling is not just a nice extra. It directly solves some of the most common chopping board complaints:
-
Board has gone rough and furry
A light sand with fine paper followed by 2 thin coats of oil will usually restore a smooth finish on both bamboo and acacia. -
Board smells of onion or garlic
Clean with a paste of salt and lemon, rinse, dry fully and then oil. The oil helps block future odours from soaking in. -
Dark stains around the meat cutting area
These stains show where juices have penetrated dry fibres. Once cleaned, oiling creates a barrier that slows this down. -
Board is starting to cup or twist
Regular oiling on both sides helps even out moisture and can reduce further movement, especially on larger 45x35cm boards.
Who this is for
Ideal for...
- Home cooks who use a wooden or bamboo chopping board at least 3 to 4 times per week
- People who want a single 45x35cm board to last 5 to 10 years with basic care
- Anyone who has invested in a quality board such as the Deer & Oak Large Acacia Board or Bamboo Double Pack and wants to protect that purchase
- Those who prefer natural materials over plastic and are happy to spend 5 minutes a month on maintenance
Not recommended for...
- People who only want completely maintenance free boards and prefer plastic or glass
- Commercial kitchens that run boards through dishwashers several times a day
- Anyone with severe nut or seed allergies who is unsure about the ingredients in some plant based oils or waxes and cannot source a clear food grade mineral oil
- Those who replace boards every 6 to 12 months and are not concerned about long term durability
FAQ
Q: Is chopping board oil really necessary if my board is already pre oiled?
A: Yes, pre oiling gives you a strong starting point, but it does not last forever. Daily washing and air drying gradually remove that protective layer. For a pre oiled Deer & Oak board, you should still plan to re oil every 3 to 6 weeks depending on how often you use it.
Q: Can I use olive oil or vegetable oil on my cutting board?
A: It is not a good idea. Cooking oils such as olive or vegetable oil can oxidise and turn sticky or rancid inside the wood. That can create unpleasant smells and attract bacteria. A food safe mineral oil or dedicated board conditioner is a better, more stable choice.
Q: How do I know when my kitchen board needs oiling again?
A: Sprinkle a few drops of water on the surface. If the water beads up for 10 to 15 seconds, the board is still protected. If it soaks in almost straight away and dark spots appear, it is time to re oil. A dry, pale or slightly rough feel is another clear sign.
Q: Does oiling make a chopping board more hygienic?
A: Oiling does not disinfect a board, but it does help with hygiene in a practical way. A well oiled surface absorbs less liquid, which means fewer juices from raw meat and vegetables can soak deep into the fibres. That makes thorough washing more effective and helps control odours.
Final recommendations and where to buy
If you want a reliable, low fuss setup, a good approach is to pick one or two quality boards and commit to oiling them regularly. For most homes, a combination like the Bamboo Double Pack DNO-BCB-2PK (45x35cm + 38x28cm, 3.0kg, Moso bamboo, £49.99) covers everyday chopping and serving with a simple monthly oiling routine.
If you prefer a darker look and slightly denser feel, the Carbonised Bamboo Board DNO-CBB-LG (45x35cm, 1.9kg, £39.99) responds very well to oil and can often go 4 to 6 weeks between treatments once settled in. For a richer wooden grain and a little extra weight under the knife, the Large Acacia Board DNO-ACB-LG (45x35cm, 2.1kg, £44.99) is a strong choice for committed home cooks.
