Yes, it is safe to wash a wooden cutting board with soap and water, as long as you use mild washing up liquid, hot water around 45–50°C, and you dry the board upright within 30 minutes. In fact, this is the best daily method for keeping a bamboo or acacia board hygienic and helping it last 5–10 years.
Is it safe to wash a wooden cutting board with soap and water?
For most home kitchens, washing a wooden cutting board with standard dish soap and hot tap water is not only safe, it is recommended. The key is how you do it:
- Use a small amount of mild washing up liquid
- Scrub for at least 20–30 seconds after cutting meat, poultry or fish
- Rinse under hot water around 45–50°C
- Dry immediately with a towel, then stand the board upright for at least 1 hour
Problems only start when a wooden board is soaked, left in a sink full of water, or put in a dishwasher. That is when warping, cracking and splitting become likely, even on thick boards like the Deer & Oak Large Acacia Board 45x35cm.
Step by step: how to wash a wooden board with soap and water
If you want your board to stay flat and food safe for years, follow this simple routine after each use.
1. Scrape first, wash second
- Use a bench scraper or the blunt side of a knife to remove food.
- For boards like the Large Bamboo Board 45x35cm this takes less than 10 seconds and prevents food from being pushed into the grain while you wash.
2. Use mild soap and hot water
- Apply 1–2 ml of mild washing up liquid directly to the board or sponge.
- Use hot tap water around 45–50°C. This is comfortably hot for hands but helps lift fats and proteins from the surface.
- Scrub both sides for 20–30 seconds, even if you only used one side. This keeps moisture balance even and reduces warping.
3. Rinse thoroughly
- Rinse until there are no visible soap bubbles. For a 45x35cm board this usually takes 10–15 seconds per side.
- Pay attention to juice grooves if your board has them, as they can trap residue.
4. Dry fast, then air dry
- Pat dry with a clean tea towel for 20–30 seconds.
- Stand the board upright on its edge or in a rack so air can circulate on both faces.
- Allow at least 1–2 hours before storing flat, or overnight if you have cut raw meat or fish.
Follow this routine with any Deer & Oak wooden board, whether it is the lighter Moso bamboo or the denser acacia. Both are designed to handle daily washing with soap and water when dried properly.
What you should never do with a wooden cutting board
Knowing what to avoid is just as important as knowing that soap and water are safe. These four habits shorten the life of any wooden board.
1. Never soak your board
Leaving a 45x35cm board in a sink of water for 30 minutes or more allows water to penetrate deep into the fibres. When the surface dries faster than the core, the board can cup or crack. This is especially risky with thicker boards that hold more moisture.
2. Never put it in the dishwasher
Dishwashers combine high heat, long exposure to water and aggressive detergents. Even a sturdy 2.1kg acacia board can twist or split after just a few cycles. Always wash by hand.
3. Avoid harsh chemicals
Bleach solutions stronger than 1 tablespoon per 1 litre of water can dry out the wood and affect the finish. If you want to sanitise, a mild diluted bleach or white vinegar solution used occasionally is enough for home use.
4. Do not leave it flat on a wet surface
Even if you dry the top, a damp worktop can keep the underside wet for hours. This uneven moisture is a common cause of slight bowing. Storing upright solves this in seconds.
How soap and water affect different wooden boards
Not all wooden boards behave the same when washed. Deer & Oak boards are made from carefully chosen materials that respond predictably to daily washing.
Bamboo boards
Boards like the Large Bamboo Board (DNO-BCB-LG) and Medium Bamboo Board (DNO-BCB-MD) are made from Moso bamboo, which is naturally less absorbent than many hardwoods. With normal washing:
- Bamboo takes on less water, so it dries relatively quickly.
- It is less prone to deep staining if cleaned within 30 minutes of use.
- A light oiling every 4–6 weeks keeps the surface conditioned.
Carbonised bamboo boards
The Carbonised Bamboo Board (DNO-CBB-LG) has a darker finish created by controlled heating of the bamboo. It can be washed with soap and water just like natural bamboo, but you may notice:
- Slightly slower drying due to its density and weight of 1.9kg.
- Marks from knives are a little less visible on the darker surface.
Acacia wood boards
Acacia boards, such as the Large Acacia Board (DNO-ACB-LG) and Medium Acacia Board (DNO-ACB-MD), are denser and heavier. When washed correctly:
- They feel very solid in the hand, even when wet.
- They benefit from slightly more frequent oiling, about every 3–4 weeks if used daily.
- They are very stable when dried upright after washing.
How washing links to board lifespan
If you wash your board correctly and oil it on a regular schedule, you can expect a lifespan of 5–10 years in a typical family kitchen. Here is how washing with soap and water fits into that picture.
- Daily: Wash with mild soap and hot water after each use, then dry upright.
- Weekly: Sprinkle coarse salt and rub with half a lemon for deeper deodorising if you cut strong smelling foods.
- Monthly: Apply a thin layer of food safe mineral oil or board conditioner and leave for at least 20 minutes before wiping off excess.
Following this pattern on a Deer & Oak wooden chopping board keeps the fibres sealed so water from washing sits mainly on the surface rather than soaking deep into the grain.

FAQ
Q: Should I use hot or cold water when washing a wooden cutting board?
A: Use hot tap water around 45–50°C with a small amount of mild dish soap. This temperature helps remove fats and food residue without shocking the wood. Always rinse and dry the board straight away to avoid water soaking in.
Q: How often should I oil my wooden cutting board if I wash it daily?
A: If you wash your board with soap and water every day, oil it every 3–4 weeks for acacia and every 4–6 weeks for bamboo. Apply a thin layer of food safe mineral oil, leave it for at least 20 minutes, then wipe away any excess.
Q: Can I disinfect a wooden board after cutting raw meat?
A: Yes, after washing with soap and hot water, you can wipe the surface with a mild bleach solution of 1 tablespoon bleach to 1 litre of water, then rinse and dry. Alternatively, white vinegar or lemon and salt can be used for extra reassurance in a home kitchen.
Q: Why does my wooden board smell even after washing with soap and water?
A: Strong foods like onion, garlic and raw meat can leave odours in the surface fibres. Sprinkle coarse salt, rub with half a lemon for 30–60 seconds, then rinse, dry and stand the board upright. Regular oiling also helps seal the surface and reduce lingering smells.
