No, you shouldn’t put a wooden chopping board in the dishwasher. A single 70 °C dishwasher cycle can warp, crack and strip oil from wood fibres, which can cut the lifespan of a wooden board from 5–10 years of daily use down to less than 1 year. If you want your board to stay flat, food safe and attractive, hand washing and quick drying are essential.
Why wooden chopping boards don’t belong in the dishwasher
Wood is a natural, porous material. In a dishwasher your board is exposed to three problems at once: high heat, soaking water and strong detergent. Together they cause:
- Warping as one side dries faster than the other
- Cracking along the grain where fibres swell then shrink
- Splitting glue joints on multi piece boards
- Stripped protective oil so the board absorbs stains and odours
That’s true for bamboo, acacia, beech and oak. Whether you’ve got a lightweight 38×28 cm prep board or a 45×35 cm butcher style board, if it’s wood, keep it out of the dishwasher.
What to do instead: the 3 step cleaning method
If you can’t put a wooden chopping board in the dishwasher, how do you keep it hygienic, especially after raw meat? Follow this simple method, which we use for every Deer & Oak board, from our 1.2 kg Medium Bamboo to our 2.1 kg Large Acacia.
1. Wash quickly with hot, soapy water
- Use washing up liquid and water at about 45–50 °C
- Scrub both sides with a non abrasive brush or sponge
- Rinse thoroughly so no soap remains in the grain
2. Disinfect when needed
- For raw meat or fish, wipe with white vinegar or a 1:20 thin bleach solution
- Leave for 2–3 minutes, then rinse with clean water
- Stand upright to drain so both faces dry evenly
3. Dry fast, then re oil regularly
- Pat dry with a clean tea towel within 2 minutes of rinsing
- Never leave your board submerged in the sink
- Every 4–6 weeks, apply food safe mineral oil or board balm
How long will a wooden chopping board last if you avoid the dishwasher?
With hand washing and regular oiling, a quality board can last:
- 5–10 years for bamboo boards used daily
- 7–12 years for dense hardwoods like acacia
In our testing, a pre oiled Large Bamboo Board DNO BCB LG (45×35 cm, 1.8 kg) kept in the dishwasher developed visible warping after 6 cycles and hairline cracks after 12. An identical board that was hand washed and oiled every 6 weeks stayed flat and smooth after 18 months of daily use.
Dishwasher safe alternatives vs wooden boards
If you absolutely want to use your dishwasher for everyday chopping, you have two clear options:
- Use a plastic or composite board for raw meat and dishwasher cleaning
- Keep a wooden board for serving and knife friendly prep, and wash it by hand
Many home cooks in the UK keep a double setup: a dishwasher safe plastic board for raw chicken and a larger wooden board for bread, fruit, vegetables and serving. Our wooden chopping boards are designed for the second role, where feel, appearance and knife care matter.

- Solution: Our Medium Acacia Board DNO ACB MD at 38×28 cm and 1.5 kg has a denser grain that resists knife marks. Kept out of the dishwasher and oiled a few times a year, it keeps its rich colour and grip.

- Solution: The Bamboo Double Pack DNO BCB 2PK pairs 45×35 cm and 38×28 cm boards. Use one for chopping and one for presentation, wash both by hand and they stay a consistent honey tone.
- Problem: You like a darker, charcuterie style board but worry about staining.
- Solution: The Carbonised Bamboo Board DNO CBB LG at 45×35 cm and 1.9 kg has a deeper colour that hides marks. Regular oiling after hand washing protects it from wine, beetroot and balsamic.
Who this is for and who it’s not for
Ideal for:
- Home cooks who want a wooden chopping board to last 5–10 years or more
- People who are happy to spend 2–3 minutes hand washing and drying after use
- Anyone who cares about knife edges and prefers a natural cutting feel
- Hosts who use their boards for serving bread, cheese or charcuterie
Not recommended for:

- Shared kitchens where items are often left soaking in the sink overnight
- People who prefer ultra thin, flexible plastic mats they can replace yearly
- Commercial environments that require fully dishwasher safe boards
FAQ
Q: What happens if I accidentally put my wooden chopping board in the dishwasher once?
A: A single cycle will not always destroy a board, but it can start fine cracks and raise the grain, especially on bamboo. Take it out as soon as you notice, dry it thoroughly on its side, then apply 2–3 coats of food safe oil over 24 hours. After that, keep it out of the dishwasher to avoid the damage getting worse.
Q: Is bamboo more dishwasher safe than other wooden boards?
A: Bamboo is slightly more water resistant than some softwoods, but it is still a natural fibre that reacts badly to high heat and harsh detergent. Our Large Bamboo Board DNO BCB LG and Bamboo Double Pack DNO BCB 2PK are both hand wash only. Treated well, they last 5–10 years, which is usually much longer than if they were put in the dishwasher.
Q: How often should I oil my wooden chopping board if I’m hand washing it?
A: For daily use, oil every 4–6 weeks, or whenever the surface looks dry and water stops beading. Apply a thin layer of mineral oil, let it soak in for at least 20 minutes, then wipe off the excess. Heavier boards like the 2.1 kg Large Acacia Board benefit from 2 coats each time.
Q: Can I use the same wooden board for raw meat and vegetables if I don’t have a dishwasher?
A: Yes, as long as you clean it properly. Wash with hot, soapy water straight after cutting meat, then disinfect with vinegar or a mild bleach solution and let it dry fully before using it for vegetables or bread. Many cooks still prefer keeping one board for meat and another for fresh produce to keep routines simple.
