No, you shouldn’t put bamboo chopping boards in the dishwasher. Repeated cycles at 60–75°C, with strong detergents and long drying times, can cause Moso bamboo boards to crack, warp and lose their protective oil within a few months, rather than lasting 5–10 years with simple hand washing.
Why bamboo chopping boards don’t belong in the dishwasher
Bamboo is a natural, eco friendly material that behaves a lot like wood. It’s tough, but it doesn’t enjoy extremes. A dishwasher combines three things that are harsh on bamboo:
- High heat: Typically 60–75°C for up to 2 hours, which dries bamboo too quickly and unevenly.
- Strong detergents: These strip away the food safe oil that protects the surface of the cutting board.
- Soaking and steam: Prolonged exposure to water causes swelling, then shrinking as it dries.
The result is usually the same: warping, hairline cracks and a rough, raised grain that’s harder to clean properly. On a large 45x35cm board, even a few millimetres of warping can make it rock on your worktop and feel unsafe when you’re chopping.
For that reason, all Deer & Oak bamboo boards, including our Large Bamboo Board (45x35cm, 1.8kg) and our Carbonised Bamboo Board (45x35cm, 1.9kg), are designed for quick hand washing only. Treat them well and you can expect 5–10 years of regular kitchen use.
How to clean bamboo chopping boards safely
If you can’t put bamboo chopping boards in the dishwasher, how should you clean them day to day? The method is simple and takes less than 2 minutes.
-
Rinse immediately after use
Scrape off food, then rinse under warm running water. Don’t leave the board soaking in the sink. -
Wash with mild washing up liquid
Use a soft sponge or brush and standard washing up liquid. Avoid bleach or harsh degreasers that strip oil. -
Rinse and dry straight away
Rinse off all soap, then dry with a clean tea towel. Stand the board upright so air can circulate around both sides. -
Disinfect when needed
For raw meat or fish, wipe with white vinegar or a 3:1 water to vinegar mix, then rinse and dry.
Used like this, a Moso bamboo cutting board stays smooth, food safe and odour free without ever going near a dishwasher.
What happens if you do put bamboo in the dishwasher?
Everyone forgets now and then. If your bamboo board has gone through the dishwasher once by accident, it is not always ruined, but you should act quickly:
- Let it cool naturally at room temperature. Don’t shock it with cold water.
- Check for warping by placing it on a flat surface. If it rocks, it may not fully recover.
- Inspect for cracks, especially at the ends and along the grain.
- Re oil the surface with food safe mineral oil or board oil to restore some moisture resistance.
One accidental cycle might shorten the life of the board but it can often still be used. Repeated dishwashing, though, will almost always reduce a potential 5–10 year lifespan to 6–18 months and increase the risk of deep cracks where moisture and bacteria can settle.
Hand wash vs dishwasher: hygiene and eco impact
It’s easy to assume that the dishwasher is always more hygienic. With bamboo chopping boards, that’s not the case. A well maintained, hand washed bamboo board can be just as hygienic as a dishwasher safe plastic board.
- Natural antibacterial properties: Bamboo has a tight grain and low porosity, which helps limit deep absorption of moisture when it’s properly oiled.
- Easy to sanitise: A 60 second scrub with washing up liquid, followed by a vinegar wipe, is enough for everyday home use.
- Eco friendly routine: Quick hand washing uses less energy than running a full dishwasher cycle just for a chopping board.
If you want an eco friendly kitchen, pairing Moso bamboo boards with a gentle hand wash routine gives you a long lasting alternative to plastic that still feels reassuringly solid under the knife.

Simple care routine to make bamboo boards last 5–10 years
With a little care, a quality bamboo chopping board can easily serve you for 5–10 years of daily use. The key is to combine quick hand washing with regular oiling.
-
Oil every 4–6 weeks
Use food safe mineral oil or a dedicated board oil. For a 45x35cm board, 1–2 teaspoons is usually enough. -
Apply to all sides
Rub the oil in with a lint free cloth on both faces and all edges. Leave it to soak for at least 20 minutes, then wipe off any excess. -
Avoid soaking
Never leave the board in a washing up bowl or under running water for long periods. -
Store upright
Stand the board on its side or in a rack so air can circulate. This helps prevent moisture build up and odours.
When a dishwasher safe board might suit you better
If you know you’ll always want to load everything into the dishwasher, then a natural bamboo or wood board probably isn’t right for you. In that case, a dishwasher safe plastic or composite board can be more practical, even if it isn’t as eco friendly.
At Deer & Oak we focus on natural materials like Moso bamboo, carbonised bamboo and acacia wood. All of these are designed for hand washing. They suit cooks who like the feel of a solid, slightly forgiving surface under the knife and who are happy to spend 60 seconds at the sink after cooking.
Who this is for
Ideal for:
- Home cooks who want eco friendly Moso bamboo chopping boards instead of plastic.
- People willing to hand wash and oil a board every 4–6 weeks to get 5–10 years of use.
- Families who like having separate boards for meat and vegetables, such as the Bamboo Double Pack (45x35cm + 38x28cm, 3.0kg).
- Anyone who prefers the look of natural bamboo or acacia on the worktop and on the table.
Not recommended for:
- People who always put every chopping board in the dishwasher without exception.
- Commercial kitchens that rely on high temperature dishwashing between every use.
- Anyone who doesn’t want to oil a board at all and prefers completely maintenance free tools.
- Households where boards are often left soaking in the sink or outside on damp surfaces.
FAQ: bamboo chopping boards and dishwashers
Q: Will one dishwasher cycle ruin my bamboo chopping board?
A: One accidental cycle usually won’t destroy a Moso bamboo board, but it can cause slight warping and strip protective oil. Let it dry slowly, check for cracks, then re oil both sides. Repeated dishwashing will almost always shorten its life from 5–10 years to well under 2 years.
Q: Are Deer & Oak bamboo boards like the Large Bamboo Board actually eco friendly?
A: Yes, our Moso bamboo boards are made from fast growing bamboo and are designed to replace several plastic boards over their 5–10 year lifespan. To keep that eco friendly benefit, they must be hand washed, not dishwashed, so they last as long as possible.
Q: Is carbonised bamboo more heat resistant in the dishwasher?
A: Carbonised bamboo, such as our 45x35cm Carbonised Bamboo Board, is heat treated for colour but it isn’t designed for dishwasher temperatures and detergents. It should still be washed by hand, just like natural Moso bamboo, to avoid warping and cracking.
Q: What’s the best way to keep bamboo chopping boards hygienic without a dishwasher?
A: Wash promptly with warm water and washing up liquid, then dry upright. For extra hygiene after raw meat, wipe with diluted vinegar and let it air dry completely. Regular oiling every 4–6 weeks helps prevent deep moisture absorption and makes the surface easier to clean.
