What oil to use on wooden cutting boards?

If you want your wooden cutting board to last 5 to 10 years, the best oil to use is a food grade mineral oil, applied in a thin coat every 3 to 4 weeks. For extra protection on boards like a 45x35cm acacia or bamboo board, follow with a beeswax and mineral oil conditioner to seal the surface and slow down moisture damage.

Oiling a 45x35cm wooden cutting board with food grade mineral oil

Why the right oil matters for wooden cutting boards

Wood is naturally porous. Every time you wash a board, water moves in and out of those pores. Without the right oil, a 45x35cm board can start to cup, crack or stain in as little as 6 to 12 months. With regular oiling using food safe mineral oil, the same board can stay smooth, stable and usable for 5 to 10 years.

The right oil should:

  • Be 100% food safe
  • Not go rancid at room temperature
  • Soak into the wood instead of sitting on top
  • Help repel water and food juices

This is why professional kitchens and serious home cooks almost always choose mineral oil and wax conditioners for their wooden boards.

What oil to use on wooden cutting boards (and what to avoid)

Best oils for wooden cutting boards

  1. Food grade mineral oil
    This is the number one choice for most wooden boards, including bamboo and acacia. It is colourless, odourless, tasteless and does not oxidise easily.
    • Use rate: 5 to 10 ml per side on a 45x35cm board
    • Frequency: every 3 to 4 weeks in a typical home kitchen
    • Benefits: helps prevent warping, cracking and deep stains
  2. Mineral oil with beeswax conditioner
    A conditioner combines mineral oil with around 20 to 30 percent beeswax to give a slightly harder, more water resistant finish.
    • Use: after a fresh coat of plain mineral oil
    • Frequency: every 1 to 2 months
    • Best for: heavy use boards, including butcher's blocks and large prep boards

Oils to avoid on wooden cutting boards

Some kitchen oils seem tempting because they are already in the cupboard. Unfortunately, many of them turn sticky and unpleasant after only a few weeks.

  • Olive oil: goes rancid and can develop a strong smell within 30 to 60 days
  • Sunflower, rapeseed, vegetable oils: oxidise and become gummy, trapping bacteria and food odours
  • Nut oils (walnut, almond) and sesame oil: can trigger allergies and also go rancid over time
  • Flavoured oils: contain herbs, garlic or chilli which can spoil and cause odours

If you remember one rule, make it this: use only food grade mineral oil and wax products that are designed for wooden boards.

How to oil a wooden cutting board in 5 simple steps

This method works for bamboo, acacia and most hardwood boards, including every Deer & Oak board listed below.

  1. Clean the board
    Wash with warm water and a small amount of mild washing up liquid. Scrub both sides, then rinse. Dry straight away with a clean towel. Do not soak the board or leave it in the sink.
  2. Let it dry completely
    Stand the board upright on its side and let it air dry for at least 6 to 12 hours. Oiling a damp board can trap moisture and shorten its life.
  3. Apply mineral oil
    Pour about 5 to 10 ml of food grade mineral oil onto the surface of a 45x35cm board. Use a lint free cloth or paper towel to work the oil into the grain, including the edges and any juice grooves. The surface should look evenly damp, not flooded.
  4. Allow the oil to soak
    Leave the board flat for 20 to 30 minutes. If any dry patches appear, add a few more drops and rub in again. For very dry boards, you can repeat this step twice.
  5. Buff off the excess
    Wipe away any remaining oil with a clean cloth until the surface feels smooth and dry to the touch. If you are using a wax conditioner, apply a thin layer now, leave for 15 minutes, then buff again.

For a new board, repeat this process 2 to 3 times in the first week. After that, once every 3 to 4 weeks is usually enough for a busy family kitchen.

How often to oil different types of wooden boards

Different woods absorb oil at different rates. For example, Moso bamboo is slightly less absorbent than acacia, so it can need oil a little less often.

  • Moso bamboo boards such as the Deer & Oak Large Bamboo Board: every 4 to 6 weeks
  • Carbonised bamboo boards such as the Deer & Oak Carbonised Bamboo Board: every 3 to 5 weeks because the darker finish shows dry patches more clearly
  • Acacia boards such as the Deer & Oak Large Acacia Board: every 3 to 4 weeks due to the slightly more open grain
  • Butcher's blocks and very thick boards: every 2 to 3 weeks during heavy use

If your board looks or feels dry, absorbs water quickly or loses its gentle sheen, it is time for another coat of oil.

Deer & Oak wooden boards and oil compatibility

Every Deer & Oak board arrives pre oiled so you can use it straight out of the box. We pre treat each board with food safe oil so the fibres are protected from the first use. After around 4 to 6 weeks, you should start your own oiling routine.

All of the following boards work well with standard food grade mineral oil and mineral oil plus beeswax conditioners:

Product and problem: matching the right board with the right care

Choosing the right oil is only half of the story. The size and material of your board affects how it behaves in a busy kitchen and how much care it needs.

  • Large Bamboo Board 45x35cm, 1.8kg
    Problem solved: You need a generous prep surface that is lighter than a thick butcher's block. Moso bamboo absorbs less water than some softwoods, so with regular mineral oil this board resists swelling and drying cycles that can cause warping.
  • Carbonised Bamboo Board 45x35cm, 1.9kg
    Problem solved: You like a darker board that hides knife marks. Carbonising can slightly open the grain, so consistent oiling with mineral oil keeps the colour even and helps prevent pale dry patches.
  • Large Acacia Board 45x35cm, 2.1kg
    Problem solved: You want a heavier, more substantial board for daily chopping and serving. Acacia has a beautiful varied grain that can dry unevenly. A 5 to 10 ml coat of mineral oil every few weeks keeps the colour rich and reduces the risk of hairline cracks.
  • Bamboo Double Pack 45x35cm + 38x28cm, 3.0kg
    Problem solved: You need separate boards for meat and vegetables without filling the cupboard. A single 100 ml bottle of mineral oil is enough for roughly 6 to 8 full treatments of both boards.

FAQ: What oil to use on wooden cutting boards?

Q: Can I use olive oil or vegetable oil on my wooden cutting board?

A: It is not a good idea to use olive oil, sunflower oil or general vegetable oil on wooden boards. These oils oxidise over time, which means they can turn sticky and rancid within 30 to 60 days and may start to smell. A food grade mineral oil stays stable for much longer and is safer for long term use.

Q: How can I tell when my board needs more oil?

A: Splash a little water on the surface and watch what happens. If the water beads into droplets, the board still has enough protection. If the water soaks in within 2 to 3 seconds or the board looks pale and feels rough, it is time for another 5 to 10 ml coat of mineral oil per side.

Q: Do bamboo and acacia boards need different oils?

A: Both bamboo and acacia work very well with the same food grade mineral oil and beeswax conditioners. The main difference is frequency. Acacia often benefits from oiling every 3 to 4 weeks, while bamboo boards like the Deer & Oak Large Bamboo Board can usually go 4 to 6 weeks between treatments in a normal home kitchen.

Q: Should I oil both sides of my cutting board?

A: Yes, always oil both sides and all four edges. Treating only one side can cause uneven moisture movement, which encourages warping over time. For a 45x35cm board, plan for 5 to 10 ml of mineral oil per side so the board stays balanced and stable.

Closing recommendations and where to buy

If you remember just one thing from this guide, let it be this: use a food grade mineral oil on your wooden cutting boards every 3 to 4 weeks. This single habit can extend the life of a board from under 1 year to well over 5 years.

For a practical everyday setup, a lot of home cooks choose the Deer & Oak Bamboo Double Pack and keep a 250 ml bottle of mineral oil nearby. If you prefer a darker look, the Carbonised Bamboo Board 45x35cm pairs nicely with a beeswax conditioner for extra protection.
