If you want your wooden or bamboo chopping board to last 5 to 10 years, the best oil to use is a food safe mineral oil applied in a thin layer every 4 to 6 weeks. For deeper protection, a board butter made from mineral oil and natural wax (such as beeswax) gives longer lasting results than using cooking oils like olive or sunflower oil, which can turn sticky and rancid.
What oil to use on chopping board: the clear answer
For any wooden or bamboo cutting board or kitchen board, including the Deer & Oak range, you should use:
- Food safe mineral oil as your everyday treatment
- Mineral oil plus wax conditioner every 2 to 3 months for extra water resistance
This applies to:
- Standard chopping boards
- Butcher's blocks
- Serving and cheese boards
All Deer & Oak boards, such as the Large Bamboo Board and Large Acacia Board, are supplied pre oiled with food safe oil so you can start using them straight away, then top up the finish at home with the same type of oil.
Oils you should and shouldn't use on a cutting board
Safe oils for chopping boards
- Food safe mineral oil Non drying, clear and odourless. It soaks into the fibres, slows down cracking and helps resist stains. This is the primary maintenance oil for all Deer & Oak kitchen boards.
- Board conditioner / board butter Usually a mix of mineral oil and beeswax or carnauba wax. It adds a light wax layer on top, which helps water bead on the surface and gives a smooth feel under the knife.
- Some hard drying oils like pure tung oil or polymerised linseed oil can be used by experienced users, but they must be fully cured and clearly labelled as food safe. For most home kitchens, mineral oil is simpler and more forgiving.
Oils to avoid on a kitchen board
- Olive oil, sunflower oil, rapeseed oil, vegetable oil These can oxidise, turn sticky and develop an odour in as little as 2 to 4 weeks. They also attract dust and can discolour the wood.
- Flavoured or infused oils Garlic, chilli or herb oils can introduce bacteria into the wood and leave strong smells that transfer to food.
- Petroleum jelly or non food grade oils Only use products that clearly state they are food safe and suitable for wooden boards or butcher's blocks.
If in doubt, choose a simple, food safe mineral oil and use it sparingly but regularly. It is inexpensive and one 250 ml bottle will usually last 8 to 12 months on a single 45x35 cm board.
How to oil a chopping board step by step
-
Clean the board
Wash the board with warm water and a small amount of washing up liquid. Rinse well and dry with a clean towel. -
Let it dry fully
Stand the board upright so air can reach both sides. Leave it for at least 6 to 8 hours until it feels completely dry to the touch. -
Apply the oil
Pour about 1 to 2 teaspoons of mineral oil onto a 45x35 cm board, or 1 teaspoon for a 38x28 cm board. Use a soft cloth or paper towel to spread it over every surface, including the edges and any juice grooves. -
Let it soak
Leave the oiled board flat for 20 to 30 minutes. If any dry patches appear, add a couple more drops of oil and rub again. -
Wipe off the excess
After soaking, buff the board with a clean, dry cloth until the surface feels smooth, not greasy. This step is important so the board does not feel sticky in use. -
Optional: wax finish
If you are using a board butter, apply a pea sized amount, rub it in with a cloth, leave it for 15 minutes, then buff until the board has a soft sheen.
For a board used daily, repeat this routine every 4 to 6 weeks. If you notice the surface looking pale, dry or rough, oil it sooner.
How oil choice affects different Deer & Oak boards
Deer & Oak boards are made from bamboo or acacia, each with slightly different care needs. The right oil helps each type last longer and stay stable.
- Moso bamboo boards like the Large Bamboo Board (DNO BCB LG) and Medium Bamboo Board (DNO BCB MD) are naturally dense and absorb a moderate amount of oil. A light coat of mineral oil every 5 to 6 weeks is usually enough.
- Carbonised bamboo boards such as the Carbonised Bamboo Board (DNO CBB LG) are heat treated to give a darker colour. They can feel slightly drier at first, so they benefit from 2 or 3 oilings in the first 3 months.
- Acacia wood boards including the Large Acacia Board (DNO ACB LG) and Medium Acacia Board (DNO ACB MD) have a richer grain and can show water spots if left unoiled. Regular mineral oil keeps the colour even and reduces movement.

How often to oil your chopping board
The right oil schedule depends on how often you use your cutting board and how you wash it:
- Daily use, washed once or twice a day Oil every 4 weeks
- Use 2 to 3 times a week Oil every 6 to 8 weeks
- Occasional entertaining board Oil every 2 to 3 months
If your board starts to look grey, feels rough or absorbs water quickly when you splash a teaspoon of water on it, it is ready for another oiling. With consistent care, a quality board like the Deer & Oak Large Bamboo or Large Acacia can stay in good condition for 5 to 10 years.
Who this is for
Ideal for...
- Home cooks who use a chopping board at least 3 times a week and want it to last several years
- People who prefer natural materials like bamboo and acacia over plastic boards
- Anyone who wants a simple, repeatable routine for caring for their kitchen board with food safe mineral oil
- Owners of Deer & Oak boards looking for clear guidance on what oil to use on chopping boards and how often to apply it
Not recommended for...
- Those who put boards in the dishwasher, as heat and steam can warp wood even if it is well oiled
- People who do not want any maintenance at all and prefer disposable or plastic cutting boards
- Commercial kitchens that require colour coded plastic boards for strict cross contamination control
- Anyone who is unable to wait for a board to dry fully before oiling, as trapped moisture can cause warping
FAQ: what oil to use on chopping board
Q: Can I use olive oil on my chopping board?
A: It is not recommended to use olive oil on a cutting board because it can oxidise and turn sticky within a few weeks. This can trap smells and make the surface harder to clean. A food safe mineral oil will stay stable and give more reliable protection.
Q: How much oil should I use on a 45x35 cm kitchen board?
A: For a standard 45x35 cm board, 1 to 2 teaspoons of mineral oil per side is usually enough. You want a thin, even film that soaks in within 30 minutes, not a thick layer sitting on top. Any excess should be wiped away so the board is not greasy.
Q: Do I need different oil for bamboo and acacia boards?
A: You can use the same food safe mineral oil on both bamboo and acacia chopping boards. Bamboo often needs a little less oil because it is quite dense, while acacia can benefit from slightly more frequent oiling to keep the colour even and the grain stable.
Q: My board is new and pre oiled. When should I first re oil it?
A: Deer & Oak boards come pre treated so you can use them immediately. For a new board used daily, the first home oiling is usually helpful after 4 to 6 weeks. If the surface still looks rich and water beads on top, you can wait a little longer before the first re oil.
