If you want your wooden cutting board to last 5 to 10 years instead of just 1 to 2, you should oil it regularly, about once every 3 to 4 weeks in a typical home kitchen. Oiling creates a moisture barrier that stops your board from warping, cracking and soaking up food juices, so it stays safer, flatter and easier to clean.
Why oil wooden cutting boards regularly?
Wood is a natural, porous material. Every time you wash your board, water pulls oils out of the wood fibres. If you do not replace those oils, the board dries out, which leads to cracks, raised grain and warping. Regular oiling replaces what washing removes and keeps the fibres flexible.
That has three practical benefits you will notice right away:
- Longer life – An oiled board can last 3 to 5 times longer than a dry one, especially in busy family kitchens.
- Better hygiene – When the surface is saturated with food safe oil, it absorbs less juice from meat and vegetables, so smells and stains do not linger as easily.
- Improved feel – Knives glide more smoothly on a conditioned board, which makes chopping more controlled and less tiring.
At Deer & Oak we pre oil every board at the factory, but that first treatment only takes you through the first 2 to 4 weeks of use. After that, regular top ups are essential if you want the board to stay in the same condition you unpacked it in.
How often should you oil different wooden boards?
Frequency matters. The same routine will not suit every kitchen or every board size. Here is a simple guide you can actually follow:
- Light use (a few times a week): oil every 4 to 6 weeks.
- Daily use for veg and bread: oil every 3 to 4 weeks.
- Heavy use for meat prep or batch cooking: oil every 2 to 3 weeks.
Larger, heavier boards like the Large Acacia Board 45x35cm or our butcher's block hold more oil in their thicker cross section, so they can often go slightly longer between treatments than thinner boards. As a rule of thumb, if the surface looks pale, feels rough or absorbs a water droplet in under 10 seconds, it is time to oil.
What happens if you do not oil wooden cutting boards?
Skipping oiling is a bit like never polishing leather shoes. They will still work, but they will age quickly and unevenly. With wooden boards, that shows up as:
- Cracks and splits – Dry wood shrinks. Over 6 to 12 months of regular washing, small hairline cracks can appear, especially on the ends.
- Warping – One side dries faster than the other, so the board can cup or twist. A 45x35cm board that no longer sits flat is frustrating and less safe.
- Staining and odours – Dry, open grain soaks up beetroot, onion and raw meat juices much more quickly.
- Rough surface – Raised grain feels fuzzy and can blunt knife edges faster.
By contrast, a regularly oiled board stays darker, smoother and more consistent across the surface. Many Deer & Oak customers use our bamboo and acacia boards daily for 3 to 5 years with only light cosmetic wear, simply by keeping up with oiling.
What oil should you use on wooden cutting boards?
For food prep surfaces, the safest choice is a food grade mineral oil or a dedicated cutting board oil that may include natural waxes. We do not recommend common cooking oils like olive or vegetable oil, because they can go rancid and leave a sticky smell within a few weeks.
Look for:
- Food safe certification on the label
- Clear and odourless so it does not affect the taste of food
- Non drying so it stays in the wood instead of forming a brittle film
All Deer & Oak boards, including the Carbonised Bamboo Board and the Acacia Board range, arrive pre treated with food grade mineral oil, so you can start using them straight away. When you re oil at home, you can use any equivalent food safe board oil.
Step by step: how to oil a wooden cutting board properly
You do not need any special tools. A clean cloth, 10 to 15 minutes and a bit of patience will give you a much nicer surface to work on.
-
Clean the board
Wash with warm water and a small amount of mild washing up liquid. Scrub both sides, rinse, then dry with a towel. -
Let it dry fully
Stand the board upright on its edge for at least 4 hours, or overnight if possible. Oiling damp wood traps moisture inside. -
Apply a thin coat of oil
Pour about 1 to 2 teaspoons of oil on a 38x28cm board, or 2 to 3 teaspoons on a 45x35cm board. Use a soft cloth or paper towel to spread it over the entire surface, including the sides and any juice grooves. -
Let the oil soak in
Leave the board flat for 15 to 20 minutes. If dry patches appear, add a few more drops and rub them in. -
Wipe off excess
Buff with a clean cloth until the surface feels dry to the touch, not greasy. Any oil left sitting on top can become sticky. -
Optional wax finish
If you want extra water resistance, finish with a thin layer of board wax and buff after 5 to 10 minutes.
Repeat this routine every few weeks and you will notice how much easier your board is to clean, especially after cutting raw meat or colourful vegetables.
Product comparison: which Deer & Oak board benefits most from regular oiling?
Different woods respond slightly differently to oil. Bamboo is naturally dense and absorbs a bit less, while acacia is a touch more open grained and rewards more frequent conditioning. Here is a side by side look at some of our most popular pre oiled boards.

Who this is for and who it is not for
Ideal for:
- Home cooks who use a wooden board at least 3 times a week and want it to last 5 to 10 years.
- People who prefer natural materials like bamboo and acacia over plastic, and are happy to spend 10 to 15 minutes a month on care.
- Hosts who use boards for serving cheese, charcuterie or roasts and want them to look presentable for guests.
Not recommended for:
- Anyone who regularly puts boards in the dishwasher, as the heat and water pressure will undo oiling very quickly.
- People who never want to do any maintenance at all and prefer to replace boards every 6 to 12 months.
- Commercial kitchens that require fully plastic boards for colour coded food safety systems.
FAQ
Q: How do I know when my wooden cutting board needs oiling?
A: Look for pale, dry patches, a slightly rough feel or water soaking in quickly instead of beading on the surface. If a teaspoon of water disappears in under 10 seconds or the board looks noticeably lighter than when you bought it, it is time to re oil.
Q: Can I use olive oil or vegetable oil on my cutting board?
A: We do not recommend it, because most cooking oils oxidise and go rancid over time, which can leave a sticky surface and an unpleasant smell. A food grade mineral oil or a dedicated cutting board oil stays stable and keeps the wood conditioned without affecting food flavour.
Q: Is oiling enough to keep my board hygienic?
A: Oiling helps by reducing how much liquid and bacteria can enter the wood, but it is not a substitute for proper cleaning. Wash your board with hot water and mild washing up liquid after each use, dry it upright and then oil it every few weeks for the best balance of hygiene and longevity.
Q: How long should a well maintained Deer & Oak board last?
A: With regular washing, no dishwasher use and oiling every 3 to 4 weeks, many customers use their boards for 5 to 10 years. Heavy chopping will leave normal knife marks over time, but the board will stay flat, smooth and safe to use if you keep up with basic care.
Which Deer & Oak board should you choose?
If you want one main prep board that rewards regular oiling, the Large Bamboo Board 45x35cm (DNO-BCB-LG) is a very practical choice. At 1.8kg it is sturdy enough to stay put on the worktop but still easy to carry to the sink, and its dense Moso bamboo responds well to a quick oil every 3 to 4 weeks.
If you prefer a richer, darker look and do a lot of serving as well as chopping, the Carbonised Bamboo Board 45x35cm (DNO-CBB-LG) adds warmth to the table while staying practical for daily prep. You can find it on our bestsellers page or directly on Amazon UK.
For households that like a two board system, one for meat and one for vegetables, the Bamboo Double Pack combines a 45x35cm and a 38x28cm board in a single set, both pre oiled and ready to go. Keep them washed, dried and oiled regularly, and they will serve your kitchen reliably for many years.
