No, you should not put eco-friendly wooden boards in the dishwasher. A single 70 °C dishwasher cycle can warp, crack and strip the protective oil from bamboo and acacia boards, cutting their lifespan from 5 to 10 years down to less than 1 year.
Why eco-friendly wooden boards should stay out of the dishwasher
Eco-friendly wooden boards, whether bamboo or hardwood, are designed to be durable when treated gently. Dishwashers use high heat, strong detergents and long soak times. That combination is harsh on natural fibres and plant based oils.
On a board like the Deer & Oak Large Bamboo Board (45x35cm, 1.8kg, Moso Bamboo), the dishwasher can:
- Cause warping within 1 to 3 washes as fibres swell and dry unevenly
- Strip food safe oil so the surface turns rough and grey in a few weeks
- Increase the chance of cracks where water and food can sit
Hand washing with warm water, a small amount of mild washing up liquid and drying upright within 10 to 15 minutes keeps the board stable and hygienic for years.
What happens if you do use the dishwasher?
If you have already put your eco-friendly wooden board in the dishwasher once or twice, it is not automatically ruined, but you may notice:
- Cupping or twisting where one side is no longer flat
- Raised grain that feels furry or rough under a tea towel
- Faded colour especially on darker carbonised bamboo
- Hairline cracks from repeated swelling and drying
If this has happened, switch to hand washing immediately and re oil the board with a food safe mineral or board oil once a week for the next 3 to 4 weeks. This will not reverse deep cracks, but it can slow further damage.
How to clean eco-friendly wooden boards safely
To keep boards like the Deer & Oak Medium Acacia Board (38x28cm, 1.5kg) in good condition for 5 to 10 years, follow this simple routine instead of using the dishwasher:
- Rinse quickly within 10 minutes of use so food does not dry on the surface.
- Wash by hand with warm (not boiling) water and a small amount of mild washing up liquid. Use a soft sponge or brush.
- Disinfect naturally once or twice a week with coarse salt and half a lemon, or a 50:50 white vinegar and water spray. Leave for 5 minutes, then rinse.
- Dry upright on its side or end so air can circulate. Avoid stacking wet boards flat.
- Oil regularly every 3 to 4 weeks, or every 2 weeks if you use the board daily.
Dishwasher vs hand wash: hygiene and lifespan
It is easy to assume the dishwasher is always more hygienic, but with wooden boards the story is different. Studies show that wood naturally draws moisture away from the surface, which helps bacteria die off more quickly than on plastic when the board is properly dried.
If you hand wash and dry a board like the Deer & Oak Bamboo Double Pack (45x35cm + 38x28cm) after raw chicken, then disinfect with vinegar or lemon and salt, it remains safe for daily use. The key is:
- Clean within 10 to 15 minutes of use
- Dry fully within 1 hour
- Oil at least every month
With this routine, a quality eco-friendly board can last 5 to 10 years. Regular dishwasher use can cut that to 6 to 18 months before cracks and warping appear.

Matching the right board to your cleaning habits
If you know you will never give up the dishwasher, a wooden board is not the right choice. Go for a dishwasher safe plastic or composite board instead and replace it every 1 to 2 years.
If you are happy to spend 2 to 3 minutes hand washing, a board like the Deer & Oak Bamboo Double Pack gives you one large 45x35cm surface for roasts and bread, and a 38x28cm board for fruit or herbs. Use one for raw meat and the other for veg to keep things simple and hygienic.
For something weightier, the acacia range offers a denser hardwood feel that stands up well to daily chopping when oiled every few weeks.
Who this is for
Ideal for...
- Home cooks who are willing to spend 2 to 5 minutes hand washing after each use
- People who want eco-friendly materials like Moso bamboo and acacia wood instead of plastic
- Families who prefer long lasting boards that can last 5 to 10 years with simple care
- Hosts who use their boards for both chopping and serving cheese, bread or charcuterie
Not recommended for...
- Anyone who insists every item must go in the dishwasher every time
- Commercial kitchens that run industrial dishwashers at very high temperatures
- People who often leave washing up until the next morning, with food dried on the board
- Users who prefer completely maintenance free tools and do not want to oil wood occasionally
FAQ
Q: Can I put my Deer & Oak bamboo board in the dishwasher just occasionally?
A: We strongly advise against it, even occasionally. One or two hot cycles can start the warping process and strip the pre oiled finish from Moso bamboo. Hand washing takes only a few minutes and will keep the board flat and smooth for several years.
Q: How often should I oil my eco-friendly wooden board?
A: If you use the board daily, oil it every 3 to 4 weeks, or every 2 weeks in a very dry kitchen. For occasional use, every 6 to 8 weeks is usually enough. When the surface looks dry or feels rough, that is a clear sign it is time to re oil.
Q: What is the best way to sanitise a wooden board after cutting raw meat?
A: First scrape any residue into the bin, then wash with warm water and a small amount of washing up liquid. Rinse, then spray with a 50:50 white vinegar and water mix or scrub with coarse salt and half a lemon. Leave for 5 minutes, rinse again and dry upright.
Q: Are bamboo and acacia boards more eco-friendly than plastic boards?
A: Bamboo and acacia come from fast growing, renewable sources and can last 5 to 10 years when cared for by hand. Plastic boards are usually dishwasher safe but often need replacing every 1 to 2 years. Choosing wood reduces plastic waste if you are willing to hand wash.
