If you want to know which board is easier to look after, carbonised or standard bamboo, the short answer is this: carbonised bamboo usually needs oiling every 6 to 8 weeks, while standard bamboo is happier with oiling every 8 to 12 weeks under the same everyday use.
Carbonised vs standard bamboo: what actually changes with oiling?
Both carbonised and standard bamboo are grasses that behave a lot like hardwood once they are laminated into chopping boards. They both need regular oiling to stop them drying, cracking and absorbing stains. The difference is in how they are treated.
Standard bamboo is kept close to its natural pale colour. It is dried and pressed, but not heat darkened. Carbonised bamboo is heated to around 150 to 200°C which caramelises the natural sugars and gives that rich, warm brown tone. This heat treatment slightly opens the structure of the bamboo, so it is a little more absorbent and a little more thirsty for oil.
In practice, this means a Deer & Oak carbonised bamboo board will usually show dry patches and a dull finish sooner than a pale standard board used in the same way. It is not a fault, it just means it needs topping up with oil a bit more often.
How often should you oil each type?
Here is a simple rule of thumb based on normal home use 5 to 7 cooking sessions per week:
- Carbonised bamboo Oil every 6 to 8 weeks
- Standard bamboo Oil every 8 to 12 weeks
If you wash your board several times a day, or it lives next to a warm oven or radiator, shorten those intervals by about 2 weeks. If your board is only used at weekends, you may stretch to the top of each range.
Every time you clean your board, check for these signs that it needs oil sooner:
- Colour looks patchy or chalky, especially on the edges
- Water no longer beads on the surface but soaks in straight away
- The surface feels slightly rough instead of silky smooth
On a Deer & Oak Carbonised Bamboo Board (SKU DNO-CBB-LG, 45x35cm, 1.9kg) these changes are easier to see because the darker surface goes from a rich brown to a flatter, lighter tone when it is thirsty.
Exact oiling routine: carbonised vs standard bamboo
The steps are almost identical. The main difference is how much oil you use and how quickly it sinks in.
Step by step for standard bamboo boards
- Clean Wash the board with warm water and a small amount of mild washing up liquid. Rinse and dry with a towel.
- Air dry Stand the board upright for at least 30 minutes until fully dry to the touch.
- First coat of oil Apply about 1 to 1.5 teaspoons of food safe mineral oil to a board around 38x28cm like the Medium Bamboo Board (DNO-BCB-MD, 1.2kg). Spread with a soft cloth, working with the grain.
- Wait Leave for 20 to 30 minutes. If the surface still looks glossy wet, gently wipe off the excess. If it looks evenly satin, you are done.
- Optional second coat For a brand new or very dry board, repeat once more.
Step by step for carbonised bamboo boards
- Clean Wash, rinse and towel dry, just as with standard bamboo.
- Air dry Stand upright for at least 45 minutes. Darker carbonised boards can hide damp patches, so give them a little longer.
- First coat of oil For a 45x35cm board like the Carbonised Bamboo Board (DNO-CBB-LG, 1.9kg) use around 2 teaspoons of oil. Spread evenly until there are no dry spots.
- Wait Leave for 30 to 40 minutes. Carbonised bamboo usually absorbs faster, so you may find it looks almost dry after the first rest.
- Second coat Add a further 1 teaspoon of oil and leave another 20 minutes. Wipe away any surface shine.
This slightly heavier oiling schedule is what keeps carbonised bamboo stable for 5 to 10 years of regular home cooking, provided you avoid soaking and dishwashers.

Product problem matching: which board solves which care issue?
Different cooks worry about different things. Here is how the main Deer & Oak options line up with real life problems.
- “I want a dark, stylish board but I do not want warping.” Choose the Carbonised Bamboo Board 45x35cm. Its 1.9kg weight and heat treated construction give a reassuringly solid feel. Just commit to oiling every 6 to 8 weeks and avoiding soaking and it will stay flat and smooth.
- “I am busy and forget to oil things.” The Large Bamboo Board 45x35cm or Medium Bamboo Board 38x28cm in standard bamboo are more forgiving. With normal use, oiling every 2 to 3 months is usually enough to prevent drying.
- “I cook a lot and want separate boards for meat and veg.” The Bamboo Double Pack gives you one 45x35cm and one 38x28cm board, both standard bamboo. You can assign one to raw meat and one to vegetables and oil them together every 8 to 10 weeks.
- “I want a weightier, more traditional feel.” The Large Acacia Board 45x35cm at 2.1kg has a denser, more timber like character. It still benefits from oiling about every 8 to 10 weeks but is less prone to showing knife marks than bamboo.
Who this is for
Ideal for...
Home cooks who want to understand exactly how often to oil their board so it lasts 5 to 10 years without cracking. If you are choosing between a dark carbonised board and a standard bamboo set, and you are happy to spend 10 minutes every couple of months on board care, this guidance is written for you. It is also useful if you are comparing a single carbonised board with a bamboo board set or acacia alternatives and want clear, numeric care expectations.
Not recommended for...
Anyone who wants a completely maintenance free surface or plans to put boards in the dishwasher. If you know you will never oil a board, even once or twice a year, a plastic or glass surface is more suitable, even though it is harsher on knives. Very high volume commercial kitchens with constant soaking and sanitising cycles should also look for specialist catering boards instead.
FAQ: Carbonised Bamboo vs Standard Bamboo Oiling Differences Explained
Q: Does carbonised bamboo need a different type of oil from standard bamboo?
A: No, both carbonised and standard bamboo should be treated with the same food safe mineral oil or a dedicated cutting board oil. The difference is quantity and frequency, not the product itself. Carbonised boards usually need slightly more oil per session and slightly more frequent applications.
Q: Will carbonising make my bamboo board last longer?
A: Carbonising mainly affects colour and oil absorption rather than lifespan on its own. A well oiled standard bamboo board can last 5 to 10 years, and a well oiled carbonised board can do the same. The deciding factor is regular oiling and sensible washing, not just the heat treatment.
Q: How can I tell if I have over oiled my bamboo board?
A: If oil is pooling on the surface or the board feels sticky after 1 to 2 hours, you have applied more than the bamboo can absorb at once. Simply wipe the surface firmly with a dry cloth until it feels satin rather than greasy, then leave it upright to finish drying overnight.
Q: Is carbonised bamboo safe for food if it is heat treated?
A: Yes, carbonised bamboo is heated without chemical additives to darken the natural sugars in the plant. Once it is fully finished and oiled, it is food safe in normal use. Just avoid harsh cleaners and dishwashers, as you would with any wooden or bamboo board.
