If you want your wooden cutting board to last 5 to 10 years instead of just 1 to 2, the single most important thing you can do is oil it regularly, roughly once every 3 to 4 weeks. Food safe mineral oil or board conditioner keeps moisture out, stops cracking and helps your board stay safer and smoother for everyday cooking.
Why oil wooden cutting board regularly instead of just once
Wood is a natural, porous material. Every time you wash your board, water pulls oils out of the fibres. If you only oil your board once when it is new, the surface gradually dries out. After roughly 3 to 6 months of regular use, an unoiled board will usually show:
- Fine cracks along the grain
- Raised fibres that feel rough under a knife
- Dark stains from meat juices or beetroot that soak into dry wood
Oiling every 3 to 4 weeks replaces those lost oils, so the wood stays saturated and more stable. On our Deer & Oak Large Acacia Board (45x35cm, 2.1kg) that can mean a working life closer to 8 to 10 years instead of 2 to 3 years with no care at all.
The 4 main problems that regular oiling solves
1. Cracking and warping
Wood moves when moisture levels change. A board that is washed daily and never oiled dries from the top faster than the bottom. That uneven drying pulls the board into a curve or creates splits. A 45x35cm board can cup by 3 to 5mm across its width in a single winter if it is left dry by a radiator.
Regular oiling slows water absorption and evaporation, which keeps the board flatter. This is especially important for larger boards like our Carbonised Bamboo Board at 45x35cm and 1.9kg, where any warp is more noticeable.
2. Stains and smells
Dry wood behaves like a sponge. Beetroot, curry, garlic and raw meat juices can soak several millimetres into the surface. Once that happens, no amount of scrubbing will fully remove the mark or odour.
When you oil a board, you fill the pores with a stable, food safe oil. Liquids then sit closer to the surface, so a quick wash within 5 to 10 minutes is usually enough to avoid deep staining. On a regularly oiled bamboo board, even onion and garlic smells tend to rinse away more easily.
3. Knife wear and rough surfaces
A dry board feels harsh. You will notice tiny splinters and raised grain, especially on cheaper or neglected boards. That rough texture grips the knife edge and can dull it faster.
Oiled wood fibres lie flatter and feel smoother. On our Moso bamboo boards, a light coat of oil every month keeps the surface almost as smooth on year three as in month one, which is kinder to both knives and hands.
4. Hygiene and cleaning
There is a common myth that oiling is only cosmetic. In reality, it affects hygiene too. An oiled board does not magically kill bacteria, but it does make thorough cleaning easier. Because liquids cannot soak in as far, hot water and washing up liquid can remove more residue from the surface.
In tests, oiled boards typically absorb less than half as much water as dry ones after a 2 minute soak. Less water inside the wood means fewer damp pockets where smells and stains can linger.
How often should you oil a wooden cutting board?
For most home kitchens, a simple rule works well:
- Every 3 to 4 weeks for daily use
- Every 6 to 8 weeks for light use (2 to 3 times a week)
- Immediately if the surface looks dry, pale or feels rough
Heavy use boards, like our 2.1kg Large Acacia Board used as a butcher style block, may benefit from a quick top up every 2 to 3 weeks. The more often you wash and dry the board, the more often you should oil it.
Exactly how to oil a wooden cutting board
If you are wondering “How do I oil my wooden board correctly?” here is a clear 5 step method you can repeat every month. It works for bamboo and acacia boards of all sizes.
-
Clean the board
Wash with hot water and a small amount of washing up liquid. Rinse and dry with a towel. Let it air dry upright for at least 2 hours so the surface is fully dry. -
Choose the right oil
Use food safe mineral oil or a dedicated board conditioner that contains mineral oil and beeswax. Avoid olive oil, sunflower oil or other cooking oils, as they can turn sticky and rancid within 2 to 3 months. -
Apply a measured amount
For a 45x35cm board, use about 2 to 3 teaspoons (10 to 15ml). For a 38x28cm board, 1 to 2 teaspoons (5 to 10ml) is usually enough. Pour small lines across the board. -
Spread and soak
Use a lint free cloth or paper towel to spread the oil in circles, covering every part of the surface, edges and any juice groove. Let it soak for 20 to 30 minutes. If any dry patches appear, add a few more drops. -
Wipe off the excess
After soaking, wipe away any oil that has not absorbed. The board should feel dry to the touch, not greasy. Stand it upright and leave it for another 4 to 6 hours before using.
Repeat the same process on the reverse side at least every second or third oiling session to keep the board balanced and flatter.
Product comparison: which boards benefit most from regular oiling?
Different woods react slightly differently to oil. Bamboo is naturally dense and absorbs a bit less oil, while acacia is slightly more open grained and drinks more. All of them benefit from regular care, but your choice of board size and weight will affect how you use and maintain it.

Because all Deer & Oak boards arrive pre oiled, you can usually wait 3 to 4 weeks after first use before your initial top up. After that, follow the timings above based on how often you cook.
Who this is for and who it is not for
Ideal for:
- Home cooks who use a cutting board at least 4 to 5 times a week and want it to last 5 to 10 years
- People who enjoy natural materials and do not mind spending 10 to 15 minutes once a month on board care
- Families who want a stable, heavy board like the 2.1kg Large Acacia Board for safe chopping
- Hosts who use boards as serving pieces and want them to stay rich in colour without grey, dry patches
Not recommended for:
- Anyone who prefers to put everything in the dishwasher and does not want any hand washing or oiling
- People who only cook once or twice a month and might be happier with a small plastic mat
- Commercial kitchens that need boards sterilised at 80°C or above in dishwashers
- Those who dislike any visible change in wood colour, as regular oiling will gently deepen the tone over time
Frequently asked questions
Q: How often should I oil my wooden cutting board?
A: For most home kitchens, oiling every 3 to 4 weeks works well for daily use. If you only cook a few times a week, every 6 to 8 weeks is usually enough. Always oil sooner if the board looks pale, feels rough or starts to show fine surface cracks.
Q: What is the best oil to use on a wooden cutting board?
A: The safest and most reliable choice is food safe mineral oil or a dedicated board conditioner with mineral oil and beeswax. Avoid olive oil, rapeseed oil and other cooking oils, as they can go rancid within a couple of months and leave sticky or sour smelling patches on the wood.
Q: Can I fix a dry or slightly cracked board by oiling it?
A: Light dryness, shallow cracks and raised grain often improve noticeably after 2 to 3 generous oiling sessions spaced 24 hours apart. Deeper splits that you can feel with your fingernail may need sanding first, and very severe cracks that run through the board are usually a sign it should be replaced for safety.
Q: Do I need to oil both sides of the board?
A: You do not have to oil both sides every single time, but it is wise to oil the reverse at least every second or third session. Keeping both faces treated helps the board stay flatter over time, especially on larger sizes like 45x35cm that are more prone to cupping if only one side is cared for.
Choosing the right Deer & Oak board and keeping it for years
If you are looking for the best wooden cutting board for everyday cooking and long term use, a medium or large bamboo or acacia board that you oil regularly is a very practical choice. Match the size to your usual prep: 38x28cm for smaller kitchens, 45x35cm if you often cook for 3 to 6 people.
For a single all rounder that will reward regular oiling, we often suggest the Large Bamboo Board DNO-BCB-LG at 45x35cm and 1.8kg. It is light enough to move easily, heavy enough to stay put while chopping, and responds very well to a 3 to 4 weekly oiling routine.
If you like a darker look and slightly heavier feel, the Carbonised Bamboo Board at 45x35cm and 1.9kg is a strong option. For households that want two sizes, the Bamboo Double Pack combines 45x35cm and 38x28cm boards at a lower combined price.
You can explore all current sizes and finishes on our Deer & Oak chopping board collection, browse ready made board sets or see what other cooks are choosing on our bestsellers page. Whichever board you pick, a small bottle of food safe mineral oil and 10 minutes a month will keep it working hard in your kitchen for many years.
