If you use your board most days, you should oil a wooden cutting board every 3 to 4 weeks, and at least every 2 months if you cook less often. Heavy daily use or a dry centrally heated kitchen can mean oiling as often as every 2 weeks, while a pre oiled board like the Deer & Oak Large Acacia Board can comfortably go 4 to 6 weeks between treatments once seasoned.
How to know when your wooden cutting board needs oil
Rather than guessing, use three simple checks to decide how often to oil your wooden cutting board:
- Colour test: If the wood looks pale, patchy or grey in spots, it needs oil within the next day or two.
- Water test: Sprinkle a teaspoon of water on the surface. If it soaks in within 30 seconds instead of beading, oil the board that day.
- Touch test: Run your hand across the board. If it feels rough, slightly furry or dry instead of silky, it is due an oiling.
For a typical home cook using a 45x35cm board like the Deer & Oak Large Bamboo Board or Large Acacia Board 4 to 5 times per week, these tests usually point to a schedule of once every 3 to 4 weeks. If you only use your board at weekends, you may find every 6 to 8 weeks is enough, as long as you store it upright and never leave it wet.
Recommended oiling schedule by wood and usage
Different woods and finishes hold oil slightly differently, so your ideal routine depends on the board you own and how you cook.
Bamboo boards
Bamboo is dense and fairly thirsty when new. For boards like the Deer & Oak Large Bamboo Board (45x35cm) or Medium Bamboo Board (38x28cm):
- First month of ownership: Oil once a week for the first 3 to 4 weeks.
- After that: Oil every 3 to 5 weeks, or when the water test shows it is absorbing quickly.
- Very dry kitchens: If you live in a flat with strong central heating, check weekly and expect to oil every 2 to 3 weeks in winter.
Pre oiled bamboo sets such as the Deer & Oak Bamboo Double Pack arrive ready to use, but still benefit from a top up after the first month, then every 3 to 4 weeks.
Acacia boards
Acacia is slightly more naturally oily and forgiving than bamboo. For boards like the Deer & Oak Large Acacia Board (45x35cm) and Medium Acacia Board (38x28cm):
- First month: Oil every 2 weeks to build a strong protective layer.
- After that: Oil every 4 to 6 weeks for regular home use.
- Heavy chopping: If you prep meat and vegetables daily, check every fortnight and oil when knife marks start to look pale.
Carbonised bamboo boards
Carbonised bamboo, like the Deer & Oak Carbonised Bamboo Board (45x35cm), is heat treated for a rich darker tone. It benefits from consistent oiling to keep that colour even:
- First month: Oil weekly.
- After that: Oil every 3 to 4 weeks.
- Colour care: If lighter patches appear, oil that evening rather than waiting.
If you want a darker board that holds its finish well, a carbonised bamboo board from Deer & Oak is designed for this kind of routine maintenance.
How to oil a wooden cutting board step by step
Oiling a board properly takes about 10 minutes of hands on time plus a few hours of drying. Here is a simple routine you can repeat every month:
- Wash and dry: Hand wash the board with mild washing up liquid and warm water. Rinse, then dry thoroughly with a clean tea towel. Let it air dry upright for at least 1 hour.
- Choose the right oil: Use food safe mineral oil, a dedicated board oil, or a board cream made from mineral oil and beeswax. Avoid olive, sunflower or other cooking oils because they can turn sticky and smell after a few weeks.
- Apply a measured amount: For a 45x35cm board, pour about 1 to 2 tablespoons of oil directly onto the surface. For a 38x28cm board, 1 tablespoon is usually enough.
- Spread evenly: Use a lint free cloth or paper towel to massage the oil into the wood, working with the grain. Do both sides and all four edges so the board stays balanced and less likely to warp.
- Let it soak: Leave the board flat on a protected surface for 20 to 30 minutes. If dry patches appear, add a teaspoon more oil to those areas.
- Buff off excess: After at least 30 minutes, wipe away any oil that has not soaked in. Buff with a clean dry cloth until the surface feels smooth, not greasy.
- Cure overnight: Stand the board upright in a rack and leave it to cure for 8 to 12 hours before using again.
Follow this routine and a quality board such as the Deer & Oak Large Acacia Board or Large Bamboo Board can easily give you 5 to 10 years of regular service.
How often to oil wooden cutting board: quick reference guide
If you just want a simple rule of thumb, match your routine to how you cook:
- Daily cooking, heavy chopping: Oil every 2 to 3 weeks.
- Cooking 3 to 5 times per week: Oil every 3 to 4 weeks.
- Weekend or occasional use: Oil every 6 to 8 weeks.
- New board, first month: Oil weekly for bamboo and carbonised bamboo, every 2 weeks for acacia.
If you are using a large, thick board such as the Deer & Oak Premium Butcher's Block, treat it like a heavy use board and oil every 2 to 3 weeks, as it will see more intense knife work.

FAQ: how often to oil wooden cutting board
Q: Can I oil my wooden cutting board too often?
A: As long as you wipe off the excess and buff the surface, oiling every 1 to 2 weeks is safe, though usually not necessary. The main risk is a slightly greasy feel if you apply too much and do not buff properly, rather than damage to the wood.
Q: What happens if I do not oil my wooden cutting board?
A: If you skip oiling for several months, the board can dry out, warp or develop small cracks where moisture and food particles can collect. Colour will fade, knife marks will look deeper and the board will be harder to clean evenly.
Q: Which oil is best for a bamboo or acacia cutting board?
A: Use food grade mineral oil or a specialist cutting board oil that is labelled as safe for contact with food. Many people like a board cream that combines mineral oil with beeswax, as it adds a light water repellent layer and can stretch oiling intervals by a week or two.
Q: How long should I wait after oiling before using the board again?
A: Let the board rest for at least 8 hours, or overnight, after oiling. This gives the oil time to soak into the grain, so the surface feels smooth and dry rather than slippery when you next prepare food.
Choosing a board that is easy to maintain
If you want a board that responds well to a simple monthly oiling routine, look for:
- Good thickness: A solid board around 2cm or more is less likely to warp when oiled on both sides.
- Pre oiled finish: Deer & Oak boards arrive pre treated so you are topping up protection, not starting from bare wood.
- Quality wood: Moso bamboo and acacia are both durable options that take oil evenly.
For busy home cooks who want one main board, the Deer & Oak Large Acacia Board or XL bamboo board pair a generous 45x35cm surface with a finish that only needs attention every few weeks. If you prefer to separate meat and vegetables, the Bamboo Double Pack lets you rotate between a 45x35cm and a 38x28cm board so each one has more drying time between uses.
Whichever size you choose, follow the simple schedule of oiling every 3 to 4 weeks, or when the water test shows the surface is starting to dry. That one small habit will keep your wooden cutting board safer, smoother and more enjoyable to use for years.
