If you have a beautiful bamboo chopping board sitting in your kitchen, you probably want it to stay that way for as long as possible. The good news? With the right oiling routine, bamboo can stay smooth, safe and good looking for years.
In this guide we will walk through the best way to oil bamboo cutting boards for longevity, with simple steps you can follow in a normal busy kitchen. No specialist tools, no faff, just proper care.
Why bamboo cutting boards need oiling
Bamboo is naturally hard wearing and more water resistant than many traditional woods, which is why we love it for everyday chopping. But it is still a natural material. Without regular oiling it can:
- Dry out and look dull or grey
- Absorb water and warp or crack
- Pick up stains and lingering odours
- Develop a rough surface that is harder to clean
A good food safe oil soaks into the bamboo, filling tiny pores and creating a gentle barrier. That helps your board repel water, resist stains and stay smooth to the touch. If you want the best way to oil bamboo cutting boards for longevity, it starts with choosing the right oil.
The best oils to use on bamboo boards
Not all oils are created equal. Some are perfect for bamboo. Others will turn sticky, go rancid or even smell a bit like the back of a cupboard. Here is what to use and what to avoid.
Best oils for bamboo longevity
-
Food grade mineral oil
Our first choice. It is clear, odourless, tasteless and does not go off. It soaks in nicely and gives a clean finish. -
Specialist board oil or board cream
These are usually mineral oil, sometimes with natural waxes like beeswax or carnauba. The wax adds an extra protective layer and a soft sheen. -
Fractionated coconut oil
This is a processed version that stays liquid and does not go rancid like normal coconut oil. Check that it is food safe.
Oils to avoid on bamboo
-
Olive oil, sunflower oil, vegetable oil and nut oils
These can oxidise and go rancid over time, leaving a sticky surface and an unpleasant smell. -
Flavoured or infused oils
Garlic or herb oils might sound lovely but they are a food safety risk on a board as they can trap bacteria. -
Varnish or furniture oil
These are not food safe and will create a hard coating that can chip and flake.
If you stick to a simple, food safe mineral oil or a quality board oil, you will be giving your bamboo the best chance of a long, hard working life.
How often should you oil a bamboo cutting board?
This depends on how often you cook and how you wash your board, but a good rule of thumb is:
- New boards Once a week for the first month
- Everyday use Once a month
- Heavy use or very dry kitchens Every 2 to 3 weeks
If you are not sure, there is a simple test. Sprinkle a few drops of water on the surface. If the water beads up, your oiling is still doing its job. If it soaks in quickly and darkens the bamboo, it is time to re oil.
At Deer & Oak our bamboo and carbonised bamboo ranges are supplied pre oiled, including our bamboo chopping board sets and our carbonised bamboo boards. That gives you a head start, but you should still top them up regularly if you want them to last.
Step by step: best way to oil bamboo cutting boards for longevity
Here is a simple routine you can follow at home. Allow around 20 to 30 minutes, most of which is just waiting for the oil to soak in.
1. Wash and dry the board properly
Start with a clean board. Wash it in warm soapy water using a soft cloth or sponge. Rinse well and dry thoroughly with a tea towel.
Then let it air dry upright for at least an hour. Oiling a damp board is one of the quickest ways to trap moisture and shorten its life.
2. Lightly sand if the surface feels rough
If your board feels a bit fuzzy or raised, you can gently sand it before oiling:
- Use fine sandpaper 220 grit is ideal
- Always sand in the direction of the grain
- Wipe away dust with a slightly damp cloth
- Let it dry again before oiling
You do not need to do this every time, only when the surface starts to feel rough or you can see small raised fibres.
3. Apply a generous but controlled amount of oil
Pour a small puddle of oil into the centre of the board, about a teaspoon to start with. Use a clean lint free cloth or paper towel to spread the oil over the entire surface, including:
- Top and bottom
- All four edges
- Any grooves or juice channels
Add more oil as needed. The surface should look wet and evenly coated but not dripping. If you have a large butcher style block like our premium butcher's block, you will need a bit more oil, especially on the end grain sides.
4. Let the oil soak in
Leave the oiled board flat on a protected surface for at least 20 minutes. For very dry or older boards, an hour or even overnight is ideal. The bamboo will drink in what it needs.
If after 20 minutes you can see dry patches, add a little more oil there and leave it again. This is the key to the best way to oil bamboo cutting boards for longevity: patience. Let the board take its time.
5. Wipe off the excess
Once the oil has had time to soak in, use a clean dry cloth to buff away any excess from the surface. You want the board to feel smooth and lightly nourished, not greasy.
Stand it upright or on its side and leave it to finish drying for a few hours before using it. Overnight is perfect if you can.
Extra tips to keep bamboo boards going for years
Oiling is only part of the story. How you use and wash your board day to day has a big impact on its lifespan.
Never put bamboo in the dishwasher
It is tempting when you are clearing up after a long day, but dishwashers are the enemy of bamboo. The heat, harsh detergents and long soak will warp, crack and strip the natural oils from your board.
Always wash by hand in warm soapy water, rinse and dry straight away.
Avoid soaking in the sink
Leaving your board floating in the washing up bowl is almost as bad as the dishwasher. Prolonged soaking lets water seep deep into the fibres. That is when you start to see warping, splitting and dark stains.
Use different sides for different jobs
If your board is double sided, it is a good idea to dedicate one side to raw meat and the other to fruit, veg and bread. This makes cleaning and food safety easier and spreads out the wear.
Our larger single boards, like the XL bamboo chopping board, are designed to be used this way, with plenty of space on each side.
Disinfect gently when needed
For everyday cleaning, warm soapy water is enough. If you have been chopping raw meat or fish and want a deeper clean, try:
- Wiping with a cloth dipped in diluted white vinegar
- Sprinkling coarse salt, then rubbing with half a lemon
Rinse and dry thoroughly afterwards, then oil again if the board looks a little dull.
Store your board where it can breathe
Try not to squash your bamboo board at the back of a damp cupboard. Store it upright or on its side, somewhere with a bit of air flow. This helps any remaining moisture evaporate and keeps the board from staying damp for too long.
What about carbonised bamboo and other woods?
If you have a darker board made from carbonised bamboo, the care is almost identical. Carbonising simply means the bamboo has been gently heat treated to deepen the colour. It still benefits from the same food safe oil and the same routine.
The same goes for acacia and other hardwood boards. At Deer & Oak we use similar pre oiling on our acacia chopping board sets so you can follow the same steps across your collection.
In summary
The best way to oil bamboo cutting boards for longevity is simple:
- Use a food safe mineral or board oil
- Clean and fully dry the board first
- Apply generously, including edges and grooves
- Let it soak in, then buff away the excess
- Repeat regularly and treat your board kindly day to day
Look after your bamboo board and it will quietly look after you in the kitchen for years, from quick weekday suppers to slow Sunday roasts. A few minutes with a bottle of oil now and then is a small price to pay for a board that stays beautiful, safe and ready for whatever you are cooking next.
