If you use your bamboo chopping board every day, you should oil it once a month, and at least every 2 to 3 months for lighter use. For new Moso bamboo boards like the Deer & Oak Large Bamboo Board, we recommend a first oiling after 2 weeks of use, then a regular monthly top up to keep the surface sealed, smooth and hygienic.
Why bamboo chopping boards need regular oiling
Bamboo is naturally dense and moisture resistant, especially high quality Moso bamboo, but it is still a natural material with tiny pores. Without oil, those pores can take in water and food juices, which leads to:
- Warping and slight cracking over time
- Raised grain and a rough cutting surface
- Staining from foods like beetroot, turmeric and berries
- Lingering odours from garlic, onion and raw meat
Food grade mineral oil or a dedicated board oil fills those pores and creates a light water resistant barrier. On a regularly oiled bamboo cutting board you will notice water beading on the surface rather than soaking in, and the colour of the board will look richer and more even.
How often should I oil a Moso bamboo chopping board?
Here is a simple schedule you can follow for any eco friendly Moso bamboo kitchen board:
- First month with a new board: Oil once after 2 weeks of use
- Daily use (1 to 3 times a day): Oil every 4 weeks
- Moderate use (a few times a week): Oil every 6 to 8 weeks
- Occasional use: Oil every 3 months
If you live in a very dry centrally heated home, or you wash your board several times a day, your bamboo may need oil slightly more often, about every 3 weeks. If the board is stored in a cooler or slightly humid kitchen, every 6 weeks is usually enough.
A good rule of thumb: if the surface looks pale, feels dry or no longer beads water, it is time to oil, even if it has been less than a month.
Step by step: how to oil a bamboo cutting board properly
Oiling is simple and usually takes 10 to 15 minutes of hands on time, plus overnight drying. Here is how to care for a Deer & Oak bamboo chopping board, whether it is a Large Bamboo Board or the Bamboo Double Pack set.
-
Clean the board
Wash the board with warm water and a small amount of washing up liquid. Wipe both sides, then rinse and dry thoroughly with a clean towel. -
Let it air dry
Stand the board on its side and allow it to dry for at least 1 hour, or until there is no visible moisture. Oiling a damp board can trap water inside the bamboo. -
Apply food safe oil
Use food grade mineral oil or a dedicated board oil. Pour about 1 to 2 teaspoons on a 45x35cm board and spread it with a soft cloth or paper towel in the direction of the grain. Cover both sides and all four edges. -
Allow the oil to soak in
Leave the board flat on a protected surface for 15 to 20 minutes. If any dry patches appear, add a few more drops of oil and spread again. -
Wipe off the excess
After at least 20 minutes, buff the surface with a clean dry cloth to remove any oil that has not soaked in. -
Leave overnight
Stand the board on its side and allow it to cure for 8 to 12 hours before using it again.
If your bamboo chopping board is very dry or brand new, repeat the oiling process twice in one evening. Two thin coats are better than one heavy coat.
How oiling frequency affects lifespan
On a well cared for Moso bamboo board, such as the Deer & Oak Large Bamboo Board or Medium Bamboo Board, you can expect a lifespan of 5 to 10 years of regular home use. Regular oiling is the single biggest factor that extends this lifespan.
- Oiled monthly: 5 to 10 years of use, surface stays smooth, fewer deep knife grooves
- Oiled once or twice a year: 2 to 4 years of use, more chance of warping or small splits
- Never oiled: noticeable drying, staining and roughness within 6 to 12 months
Because bamboo is a fast growing eco friendly material, caring for one board for 7 years instead of replacing it every 2 years also reduces waste and the energy used in production and shipping.
Bamboo vs carbonised bamboo vs acacia: care and oiling needs
Deer & Oak offers several eco friendly chopping board options. All benefit from regular oiling, but some need it slightly more or less often.
- Moso Bamboo (for example the Large Bamboo Board DNO-BCB-LG and Medium Bamboo Board DNO-BCB-MD): Needs oil about once a month with daily use. Light in colour, very durable and kind to knives.
- Carbonised Bamboo (for example the Carbonised Bamboo Board DNO-CBB-LG): Heat treated for a darker tone. Slightly more resistant to staining but still needs oil every 4 to 6 weeks to keep the rich colour.
- Acacia Wood (for example DNO-ACB-LG and DNO-ACB-MD): Denser hardwood, holds oil well. Usually needs oil every 6 to 8 weeks with normal use.
If you prefer a darker board that hides marks a little better, a carbonised bamboo board is a strong option. If you want a more traditional hardwood feel, an acacia chopping board set may suit you better.

Common problems oiling helps to solve
Oiling is not just about appearance. It directly tackles specific problems that many people have with bamboo cutting boards:
-
Board feels rough or furry
Regular oiling smooths raised grain and keeps knife work comfortable. -
Dark stains and food marks
A well oiled board is less porous, so stains are lighter and scrub off more easily. -
Unpleasant smells
Oil reduces how deeply juices soak in, so odours rinse away instead of lingering. -
Edges starting to lift or hairline cracks
Keeping the bamboo fibres nourished with oil lowers the risk of small splits forming.
If you already have some staining or odour, you can gently scrub the dry board with a paste of coarse salt and lemon, rinse, dry fully, then oil. This often restores even older eco friendly bamboo kitchen boards quite well.
Who this is for and who it is not for

- Home cooks who use a chopping board most days and want it to last 5 to 10 years
- People who prefer eco friendly materials like Moso bamboo and want a simple care routine
- Anyone who does a Sunday prep session and is happy to oil a board every 4 to 6 weeks
- Families who like separate boards for meat and vegetables and want clear, repeatable care steps
Not recommended for
- People who never want to do any maintenance at all, even once a month
- Commercial kitchens that run boards through dishwashers many times a day
- Anyone who regularly soaks boards in water or leaves them in the sink overnight
- Those who prefer plastic boards that can go in the dishwasher instead of natural materials
FAQ
Q: What oil should I use on my bamboo chopping board?
A: Use food grade mineral oil or a board oil that clearly states it is safe for food contact. Avoid olive oil, sunflower oil and other cooking oils, as they can go sticky or rancid over time. If you like a slightly waxy finish, you can use a blend of mineral oil and beeswax after the first coat of plain oil has soaked in.
Q: Can I over oil my bamboo cutting board?
A: It is difficult to truly over oil a board, but very heavy coats that are not wiped back can leave a tacky surface. If the board still feels oily after 12 hours, simply buff it with a dry cloth until it feels smooth and dry. Sticking to one thin coat every 4 to 6 weeks is usually ideal for Moso bamboo.
Q: Do I need to oil both sides of the board?
A: Yes, you should always oil both sides and all four edges. Treating only one side can create uneven moisture levels, which increases the chance of slight warping. Oiling both faces keeps the bamboo fibres balanced and helps the board stay flat on your worktop.
Q: How do I know when it is time to re oil my bamboo board?
A: Sprinkle a few drops of water on the surface and watch what happens. If the water beads up and sits on top, the oil is still doing its job. If it quickly soaks in and darkens the bamboo, it is time to clean, dry and oil again. Many Deer & Oak customers find this happens at about the 4 week mark with daily use.
Recommended Deer & Oak boards for easy care
If you want an eco friendly bamboo kitchen board that responds well to a simple monthly oiling routine, two options stand out:
-
Large Bamboo Board DNO-BCB-LG
At 45x35cm and 1.8kg, this Moso bamboo board gives plenty of space for family meals while still being easy to lift and oil. It arrives pre oiled, so you can start using it straight away and then follow the once a month oiling routine. You can find similar boards in our bamboo chopping board collection. -
Bamboo Double Pack DNO-BCB-2PK
This set pairs a 45x35cm board with a 38x28cm board, both in Moso bamboo with a total weight of 3.0kg. Many people use one for meat and one for vegetables, then oil both at the same time every 4 weeks. It is available as a bamboo chopping board double pack for UK customers.
If you prefer a darker board with the same simple care, the Deer & Oak bestsellers include carbonised bamboo and acacia options that also respond very well to regular oiling. Whichever board you choose, sticking to a clear schedule of oiling every 4 to 6 weeks will keep it looking good and working hard in your kitchen for many years.
