If you want your wooden or bamboo kitchen board to last 5 to 10 years, the simplest method is to apply a thin coat of food safe mineral oil every 3 to 4 weeks, using about 1 to 2 teaspoons per side on a standard 45x35cm board. Work the oil in with a soft cloth, let it soak for at least 20 minutes, then wipe away any excess so the surface is dry to the touch.
Why oiling your cutting board matters
Every time you wash a chopping board, a little moisture escapes from the wood or bamboo. Without oil, your board can dry out in as little as 3 to 6 months, leading to cracks, raised grain and staining. Regular oiling:
- Helps prevent warping and splits
- Reduces deep staining from beetroot, turmeric and meat juices
- Makes the surface smoother and kinder to your knives
- Extends the life of a quality board from 1 to as much as 10 years
All Deer & Oak boards, such as the 45x35cm Carbonised Bamboo Board, arrive pre oiled, but regular top ups keep them in their best condition.
Step by step: how to apply oil to chopping board
1. Clean and dry the board properly
- Wash the cutting board with warm water and a small amount of mild washing up liquid.
- Scrub gently with a soft sponge or brush, following the grain.
- Rinse and dry with a clean tea towel straight away.
- Let the board air dry standing upright for at least 2 to 3 hours, or overnight if it feels at all damp.
Never soak your kitchen board or put it in the dishwasher. A 45x35cm board that takes on too much water can twist by several millimetres in a single wash cycle.
2. Choose the right oil
For food contact, stick to food safe, non drying oils. The three most common options are:
- Food grade mineral oil The simplest option. Clear, odourless and does not go rancid.
- Specialist board oil or conditioner Often a blend of mineral oil and natural waxes such as beeswax or carnauba wax.
- Fractionated coconut oil Stays liquid and stable, unlike standard cooking coconut oil.
Avoid olive oil, sunflower oil and other everyday cooking oils. They can turn sticky and develop an off smell within weeks.
3. Measure how much oil to use
Use these simple amounts as a guide per side:
- 45x35cm board 1 to 2 teaspoons (5 to 10 ml)
- 38x28cm board 0.5 to 1 teaspoon (3 to 5 ml)
A board that is very dry may need a second or third coat on the first treatment. It is better to apply 2 or 3 light coats than one heavy one.
4. Apply the oil evenly
- Place the board on a clean tea towel or baking paper.
- Drizzle the measured oil directly on the surface in a zigzag.
- Use a lint free cloth, piece of kitchen roll or your hand to spread the oil.
- Work with the grain, from one end to the other, until the surface looks evenly damp, not puddled.
Do the main cutting surface first, then the reverse side, then the edges and any juice grooves. A 45x35cm board such as the Deer & Oak Large Bamboo Board usually takes about 3 to 4 minutes to coat fully.
5. Let the oil soak in
Leave the board lying flat for at least 20 minutes. For very dry boards, 1 to 2 hours is even better. If the surface looks dry again after 20 minutes, add another light teaspoon of oil and repeat.
6. Wipe off the excess
After the soak time:
- Use a clean, dry cloth to buff the surface.
- Remove any shiny or wet patches so the board feels dry and silky, not greasy.
- Stand the board on its side for another hour so both faces can breathe.
Used correctly, oil should not transfer to food. If your knife or hands feel oily after use, you simply need a more thorough final buff next time.
How often to oil your kitchen board
Frequency depends on how often you cook and the climate in your kitchen. As a starting point:
- Daily use in a dry, centrally heated kitchen: every 3 weeks
- Regular use (3 to 4 times a week): every 4 to 6 weeks
- Occasional use: every 2 to 3 months
A simple test is the water droplet test. Sprinkle a few drops of water on the cutting surface. If they bead up, the board is still protected. If they soak in within 5 to 10 seconds, it is time to oil again.
Extra care for different board materials
Bamboo boards
Bamboo is naturally dense and slightly less absorbent than many hardwoods, so it often needs a little less oil. Our bamboo chopping boards such as the Large Bamboo Board and Medium Bamboo Board are made from Moso bamboo, which is strong and stable.
- Use the lower end of the oil range 1 teaspoon per side for a 45x35cm board.
- Pay attention to the ends and any seams, as these can dry out first.
- Expect to oil every 4 to 6 weeks with normal use.
Acacia and other hardwood boards
Acacia is slightly more open grained than bamboo, so it may drink more oil, especially at first. Our Large Acacia Board at 45x35cm and 2.1kg, for example, benefits from a generous first treatment when new.
- Start with 2 teaspoons per side on the first two or three oilings.
- Once conditioned, move to 1 teaspoon per side every 3 to 5 weeks.
- Use a conditioner with wax once every 2 to 3 months for extra sheen.

FAQ
Q: How often should I apply oil to my chopping board?
A: For a board that is used daily, oiling every 3 to 4 weeks is usually enough. If you cook less often, every 6 to 8 weeks can work. Use the water droplet test: if water soaks in within 10 seconds instead of beading, it is time to re oil.
Q: Which oil is safest to use on a kitchen board?
A: Food grade mineral oil is the simplest and most reliable choice, as it does not go rancid and has no strong smell. Specialist board oils and conditioners are also suitable, as long as they are clearly labelled as food safe. Avoid ordinary cooking oils such as olive or vegetable oil, which can become sticky.
Q: Do I need to oil a brand new Deer & Oak board?
A: All Deer & Oak chopping boards arrive pre oiled, so you do not need to oil them on the first day. After about 3 to 4 weeks of use, check the surface. If it looks a little dry or water no longer beads, give it a light oiling to top up the protection.
Q: Can I use the same oiling routine for bamboo and acacia boards?
A: Yes, the method is identical, though acacia often needs slightly more oil on the first few treatments. A 45x35cm bamboo board might need 1 teaspoon per side, while a 45x35cm acacia board may take 1.5 to 2 teaspoons. Once both are conditioned, you can oil them on the same monthly schedule.
