If you want your wooden chopping board to last 5 to 10 years, a simple routine of mineral oil every 4 weeks plus board butter every 2 to 3 months is usually better than using mineral oil on its own. Mineral oil soaks deep into the wood to stop it drying out, while board butter sits closer to the surface to seal, smooth and protect.
What is better for wood maintenance: board butter or mineral oil?
For long term wood maintenance on chopping boards, butcher blocks and serving platters, mineral oil is the base treatment and board butter is the upgrade. Mineral oil keeps the fibres of bamboo and hardwood hydrated so they are less likely to crack. Board butter adds waxes that slow water absorption, help resist stains and give a smoother cutting surface.
If you only choose one product, food grade mineral oil is the minimum you should use on any untreated wooden board. If you want your board to resist marks and water rings more effectively, adding a wax based board butter on top is worth it, especially on larger and heavier boards such as a 45x35cm piece that weighs over 1.8kg.
How mineral oil works on bamboo and hardwood boards
Mineral oil is a clear, odourless, food safe oil that does not go rancid. For wood maintenance it has one job: soak into the wood and replace the natural oils that are washed away by water and washing up liquid.
- Deep penetration Mineral oil is thin so it travels several millimetres into the grain. On a 45x35cm Moso bamboo board this can mean the entire surface layer is hydrated evenly.
- Hydration and movement Hydrated fibres move more gently with changes in humidity, which reduces the risk of warping and hairline cracks.
- Neutral finish It does not change the colour of light bamboo very much, so boards like the Deer & Oak Large Bamboo Board stay close to their natural tone.
On its own, mineral oil is usually enough for boards that see light to medium use, such as a 38x28cm board that you use for vegetables once a day. For heavy daily chopping, carving joints or using both sides of a board, pairing oil with a wax rich board butter gives better surface protection.
What board butter adds that mineral oil cannot
Board butter is typically a blend of mineral oil with beeswax and sometimes plant waxes. Think of it as a moisturiser and raincoat in one. It is thicker than oil, so it sits closer to the surface.
- Surface seal The wax forms a very thin barrier that slows how quickly water, meat juices and wine soak into the wood.
- Smoother feel Wax fills tiny pores and knife tracks, which can make a 2.1kg acacia board feel noticeably smoother under the knife.
- Richer colour On darker woods such as carbonised bamboo or acacia, board butter brings out the grain and can deepen the tone by a small but visible amount.
Board butter is not a replacement for mineral oil, because it does not travel as deep into the wood. The most reliable routine is to oil first, let it soak in fully, then finish with a thin layer of board butter.
How often to use board butter vs mineral oil
The exact timing depends on how often you use your board and how you wash it, but these are practical starting points for Deer & Oak boards:
-
Light use 2 to 3 times a week, mostly veg and bread
Mineral oil every 6 weeks, board butter every 3 to 4 months. -
Daily home cooking 1 to 3 times a day, mixed use
Mineral oil every 4 weeks, board butter every 2 to 3 months. -
Heavy use Meal prep for a family of 4 or more, or small food business
Mineral oil every 2 to 3 weeks, board butter every 4 to 6 weeks.
A simple test: drip a teaspoon of water on the centre of your board. If the water soaks in within 30 seconds instead of beading on the surface, it is time to re oil and re butter.
Step by step: how to treat a Deer & Oak board
These steps apply to all our sizes, from the 38x28cm Medium Bamboo Board up to a 45x35cm Large Acacia Board or carbonised board.
-
Clean and dry
Wash the board with warm water and a small amount of mild detergent. Rinse and dry with a towel, then let it air dry upright for at least 12 hours until the surface feels completely dry. -
Apply mineral oil
Pour about 10 to 15ml of food grade mineral oil onto a 45x35cm board, or 5 to 10ml for a 38x28cm board. Spread it with a lint free cloth in the direction of the grain, covering both sides and all edges. -
Let it soak
Leave the board flat for 20 to 30 minutes. If any dry patches appear, add a few extra drops. For very dry boards, repeat this step once more. -
Wipe off excess
Buff the surface with a clean cloth until it feels dry to the touch. There should be no oily residue left on the surface. -
Finish with board butter
Take a pea sized amount of board butter for a 38x28cm board or a marble sized amount for a 45x35cm board. Warm it between your fingers, then rub it over the surface in small circles. Leave for 15 minutes, then buff until the board feels silky rather than waxy.
Why this matters more on large and heavy boards
Larger boards carry more weight and surface area, which makes them more sensitive to uneven moisture. A 45x35cm Large Bamboo Board (DNO-BCB-LG) weighs 1.8kg and a 45x35cm Large Acacia Board (DNO-ACB-LG) weighs 2.1kg. If one corner sits in a damp patch or near a sink, the wood can swell unevenly and start to rock on the worktop.
Regular mineral oil helps the whole board react more evenly to humidity. Board butter gives the surface extra resistance to the puddles and spills that naturally happen around a busy hob. If you use a heavy board as a serving platter for cheese, meat or juicy roasts, the wax layer also makes it easier to wipe away fat and proteins before they stain.

Product problem pairs: which treatment for which board?
-
Problem Light coloured bamboo looks dry and feels rough after 6 months
Better choice Regular mineral oil on a Large Bamboo Board or Bamboo Double Pack, with board butter every few months to keep the surface smooth. -
Problem Dark board shows water rings and meat juices more easily
Better choice A Carbonised Bamboo Board treated with both mineral oil and board butter so the wax layer slows staining. -
Problem Heavy acacia serving board used for roasts and cheese platters
Better choice Large Acacia Board with a generous coat of mineral oil and a slightly thicker layer of board butter around the juice channels and edges. -
Problem One side of a medium board starts to cup or rock on the worktop
Better choice Treat both sides of a Medium Bamboo or Medium Acacia Board evenly with mineral oil, then board butter, so moisture levels stay balanced.
Who this is for
Ideal for home cooks who use wooden or bamboo boards at least twice a week, anyone who owns a 45x35cm or 38x28cm Deer & Oak board, and people who want their boards to last 5 to 10 years with a simple 10 minute care routine each month.
Not recommended for people who put boards in the dishwasher, those who prefer disposable or plastic boards that need no maintenance, or anyone unwilling to spend a few minutes every few weeks oiling and buffing their wooden boards.
FAQ: board butter vs mineral oil for wood maintenance
Q: Should I use board butter or mineral oil first?
A: Always use mineral oil first, because it needs to soak deep into the wood. Once the surface feels dry and the oil has absorbed, apply a thin layer of board butter on top to seal and smooth the surface.
Q: Can I use only mineral oil and skip board butter?
A: Yes, you can maintain a board with mineral oil alone, especially if it only sees light use. Adding board butter is helpful if you want better resistance to water and stains, or if your board feels rough after a few months.
Q: How much product do I need for a 45x35cm board?
A: For a 45x35cm board you will usually need 10 to 15ml of mineral oil per treatment and a marble sized amount of board butter. That is normally enough to cover both sides and all edges without leaving a sticky residue.
Q: Does board butter make the board slippery or affect knife safety?
A: When buffed properly, board butter leaves a satin finish that is not slippery. The wax fills tiny pores but does not form a thick coating, so your knife still bites into the wood and the board stays safe to use.
Closing recommendations and where to buy
If you want a straightforward answer for everyday cooking: use food grade mineral oil as your base treatment and add board butter as a protective top coat. For most home kitchens, oiling every 4 weeks and buttering every 2 to 3 months will keep a Deer & Oak board in good condition for many years.
If you are choosing a new board to care for, the Bamboo Double Pack in 45x35cm and 38x28cm gives you a prep board and a serving board that respond very well to both mineral oil and board butter. If you prefer a darker finish, our Carbonised Bamboo Board offers a rich tone that looks especially good once waxed.
