If you want your wooden cutting board to last 5 to 10 years instead of just 1 to 2, you should oil it every 2 to 4 weeks after cleaning. Oiling right after the board has fully dried keeps water out, stops cracks from forming and helps your board stay up to 3 times more resistant to warping and staining.
Why oil wooden cutting board after cleaning?
Wood and bamboo are naturally porous. When you wash a board, water is pulled into those pores. If you leave the board bare, that moisture can escape unevenly which leads to warping, raised grain and hairline cracks. Oiling after cleaning fills the pores with food safe oil instead, so water and food juices cannot soak in as easily.
On a practical level, that means:
- Fewer stains from beetroot, turmeric and meat juices
- Less chance of deep knife grooves harbouring smells
- A smoother surface that is kinder to knife edges
- A longer useful life for your board, especially larger pieces like our 45x35cm options
At Deer & Oak we pre oil boards such as our Carbonised Bamboo Board, but regular top ups at home are still essential if you want that fresh, rich finish to last.
What actually happens when you oil a board?
When you apply a thin coat of mineral oil or board conditioner, the oil is drawn into the wood fibres. This does three important jobs:
-
Moisture balance
Oiled fibres hold a stable level of moisture. That reduces expansion and contraction, so a 45x35cm board is less likely to cup or twist over time. -
Barrier against liquids
The oil acts as a partial seal. It will not make your board waterproof, but it slows down how quickly water, wine or meat juices can soak in. -
Smoother cutting surface
Dry wood fibres stand up and feel rough. Oiled fibres lie flatter, so your knife glides more easily and the board is simpler to wipe clean.
This is why our pre oiled boards, like the Deer & Oak bamboo and acacia range, arrive with a deep, even sheen rather than a pale, chalky look.
When should you oil a wooden cutting board?
The best time to oil is after cleaning, once the board is completely dry. For most home kitchens:
- Frequency: every 2 to 4 weeks for daily use, or whenever the surface looks dry and patchy
- After heavy scrubbing: always re oil if you have used vinegar, lemon or coarse salt on the surface
- Climate: in centrally heated homes, larger boards like our 2.1kg Large Acacia Board may need oil slightly more often in winter
A simple rule: if water no longer beads on the surface and instead disappears within 10 seconds, it is time to oil.
Step by step: how to oil your board after cleaning
Here is a practical routine you can follow with any Deer & Oak board, from the 38x28cm Medium Bamboo Board to the 45x35cm Carbonised Bamboo Board.
-
Wash
Hand wash with warm water and a small amount of washing up liquid. Scrub both sides, even if you only used one. -
Rinse and dry
Rinse thoroughly, then towel dry. Stand the board upright so air can reach both faces. Leave it to dry for at least 12 hours. -
Apply oil
Use a food safe mineral oil or board conditioner. Pour about 5 to 10 ml onto a 45x35cm board or 3 to 5 ml for a 38x28cm board. Spread with a lint free cloth in the direction of the grain. -
Let it soak
Leave the oiled board flat for 20 to 30 minutes. If areas look dry, add a few more drops. -
Buff off excess
Wipe away any remaining oil with a clean cloth. The surface should feel dry, not greasy. -
Optional wax finish
If you want extra water resistance, use a beeswax and mineral oil blend once every 2 or 3 months.
Product and problem: matching your board to your care routine
Different woods behave differently, so choosing the right board helps match the care routine to your cooking style.
- Moso bamboo boards such as our Large Bamboo Board (45x35cm, 1.8kg) and Medium Bamboo Board (38x28cm, 1.2kg) are naturally dense and need light but regular oiling to keep fibres from drying out.
- Carbonised bamboo like the 45x35cm, 1.9kg Carbonised Bamboo Board is heat treated which deepens the colour and makes the board slightly more stable, but it still benefits from the same oiling routine.
- Acacia wood boards such as the Large Acacia Board (45x35cm, 2.1kg) and Medium Acacia Board (38x28cm, 1.5kg) have a higher natural oil content, so they hold their finish longer but still need topping up every few weeks to prevent pale, dry patches.
If you want to set yourself up with a simple system, our Bamboo Double Pack gives you a 45x35cm board for mains and a 38x28cm board for fruit or bread. Oil them together on the same day and you have an easy routine you will actually keep.

Who this is for and who it is not for
Ideal for:
- Home cooks who use a board daily and want it to last at least 5 years
- People who enjoy the look of natural materials and are happy to spend 10 minutes a month on care
- Those choosing larger, heavier boards from 1.8kg to 2.1kg who want to avoid warping on worktops
- Hosts who use boards as serving pieces and want a rich, even colour for cheese, meats and breads
Not recommended for:
- Anyone who prefers to put everything in the dishwasher with no hand washing
- Commercial kitchens that need boards sanitised at high temperatures many times a day
- People who know they will never remember to oil a board every few weeks
- Those who want a completely maintenance free surface and might be happier with plastic
FAQ
Q: Can I skip oiling if my board is pre oiled from the factory?
A: No, pre oiling is a starting point, not a lifetime treatment. Even a pre oiled board like a Deer & Oak acacia or carbonised bamboo piece will slowly dry out with washing and air exposure. Plan to top up the oil every 2 to 4 weeks depending on how often you use it.
Q: What type of oil should I use on my wooden cutting board?
A: Use a food safe mineral oil or a dedicated board conditioner that combines mineral oil and wax. Avoid olive, sunflower and other cooking oils because they can turn sticky and develop smells over time. A simple 100 percent mineral oil is affordable and works reliably.
Q: How do I know if I have used too much oil?
A: If the board still feels greasy or leaves marks on a clean tea towel after 30 minutes, you have used more oil than the wood can absorb. Just buff the surface with a dry cloth until it feels smooth and dry. The excess will come off and the absorbed oil will stay in the fibres.
Q: Will oiling my board make it completely waterproof and stain proof?
A: No, oiling improves resistance but does not make the board waterproof. Liquids will still mark if left to pool for a long time, especially strong colours like beetroot or red wine. Wipe spills within a few minutes and wash the board soon after use to get the best results from your oiling routine.
