The best way to sanitize a wooden cutting board is to wash it within 5 minutes of use with hot water at about 60°C and washing up liquid, then disinfect with either white vinegar or a 1:10 bleach solution, and let it air dry upright for at least 8 hours. Done properly, this routine helps a quality board like the Deer & Oak Large Bamboo Board (45x35cm, 1.8kg) stay hygienic for 5 to 10 years of daily cooking.
Why wooden boards need a specific sanitising routine
Wood behaves very differently to plastic. It is naturally porous and can absorb small amounts of liquid, which is actually helpful. Bacteria tend to be drawn into the surface where they dry out and die, instead of sitting in shallow knife scars as they often do on hard plastic.
That said, raw meat juices, fish and eggs still carry a risk if they are left on the board for more than 15 to 20 minutes. Regular, consistent sanitising is what keeps a wooden board safe. The routine below works on bamboo, acacia and traditional hardwoods, including Deer & Oak boards between 38x28cm and 45x35cm.
Step by step: the best way to sanitise a wooden cutting board
1. Scrape and rinse immediately
- Within 5 minutes of finishing prep, scrape off food with a bench scraper or spatula.
- Rinse the board under hot running water for 10 to 20 seconds.
Quick action stops proteins and fats from binding to the wood fibres, which makes sanitising more effective.
2. Wash with hot water and washing up liquid
- Use water at about 55 to 60°C. It should be hot but comfortable with gloves.
- Apply washing up liquid directly to a non scratch brush or sponge.
- Scrub both sides of the board for 30 to 45 seconds, paying attention to knife marks and the juice groove if your board has one.
For a board the size of the Deer & Oak Large Acacia Board at 45x35cm and 2.1kg, work in sections so you cover the whole surface evenly.
3. Choose your sanitiser: vinegar or diluted bleach
After washing, you sanitise. There are two kitchen friendly options that work well on bamboo and acacia.
Option A: White vinegar (everyday use)
- Mix equal parts white vinegar and water, for example 100 ml vinegar with 100 ml water.
- Spray or wipe the solution over the entire surface.
- Leave for 5 minutes, then rinse with warm water.
Vinegar is gentle on the wood and ideal for boards used mainly for bread, fruit, vegetables and cheese.
Option B: 1:10 bleach solution (after raw meat or fish)
- Mix 1 part thin, unscented household bleach with 10 parts water, for example 10 ml bleach with 100 ml water.
- Apply with a clean cloth or spray bottle so the surface is evenly wet, not dripping.
- Leave for 2 minutes, then rinse very thoroughly with hot water.
This is especially useful on a dedicated meat board, such as a Deer & Oak Carbonised Bamboo Board used for poultry and beef. Do not soak the board in bleach, as prolonged immersion can dry and crack the wood.
4. Dry correctly: upright and fully exposed
- Immediately after rinsing, stand the board upright on its long edge.
- Leave at least 3cm of air space on both sides.
- Allow 8 to 12 hours to dry fully, ideally overnight.
This is one of the most important steps. A 1.8kg bamboo board or a 2.1kg acacia board holds more moisture than a small plastic mat. Trapped water encourages warping and can support mould in the long term.
Deep sanitising for stained or smelly boards
Sometimes you need more than a quick clean. Garlic, onion, raw lamb and oily fish can leave odours, especially on the heavier 45x35cm boards that see a lot of use.
Salt and lemon scrub
- Sprinkle 1 to 2 tablespoons of coarse salt over the board.
- Cut a lemon in half and use the cut side to scrub the salt into the surface for 1 to 2 minutes.
- Leave for 5 minutes, then rinse with hot water and wash as normal.
The salt acts as a gentle abrasive, while the citric acid helps lift stains and neutralise smells. This method is safe on both Moso bamboo and acacia wood.
Hydrogen peroxide for stubborn meat juices
- Use 3% hydrogen peroxide, the standard pharmacy strength.
- Pour a thin layer over the surface and spread with a clean cloth.
- Let it sit for 5 minutes until it stops fizzing.
- Rinse, wash and dry as usual.
This is a helpful extra step if you have been prepping raw chicken on your dedicated meat board and want extra reassurance.
How often should you sanitise a wooden board?
- After every use: Wash with hot water and washing up liquid.
- After raw meat, poultry or fish: Wash, then sanitise with 1:10 bleach solution or hydrogen peroxide.
- Weekly: Deep clean with salt and lemon if you cook daily.
- Monthly: Re oil the board if it looks dry, especially on the ends.
With this routine, a well made board such as the Deer & Oak Bamboo Double Pack can stay in daily service for 5 to 10 years without becoming stained or unsafe.
Why board quality affects how well it sanitises
Not all wood is equal when it comes to hygiene. Dense, close grained materials like Moso bamboo and acacia resist deep cuts and absorb less liquid. This means fewer places for bacteria to hide and a better response to your sanitising routine.
Deer & Oak boards are pre oiled, which slows moisture absorption. A pre oiled 45x35cm board will usually dry in around 8 hours. A dry, un oiled board of the same size can stay damp at the core for 12 hours or more, which is not ideal for hygiene or longevity.

Who this is for and who it is not for
Ideal for: Home cooks who want a clear, repeatable routine to keep wooden boards safe for daily use. Families who prep both raw meat and fresh produce and like the idea of separate 45x35cm and 38x28cm boards. Anyone who prefers natural materials like Moso bamboo or acacia and is happy to spend 2 to 3 minutes on care after cooking.
Not recommended for: People who want to put boards in a dishwasher or leave them soaking in the sink. Commercial kitchens that must follow strict, plastic only food safety policies. Anyone who knows they will not wash up promptly and would rather use disposable or dishwasher safe plastic mats.
FAQ: sanitising wooden cutting boards
Q: Can I put my wooden cutting board in the dishwasher to sanitise it?
A: No, dishwashers run at high heat for 60 to 120 minutes and keep the board soaked the whole time. This can cause warping, cracking and splitting, especially on larger 45x35cm boards. Hand washing with hot water at about 60°C and a quick sanitising step is both safer for the board and effective for hygiene.
Q: How often should I use bleach on a wooden cutting board?
A: Use a 1:10 bleach solution only after handling raw meat, poultry, fish or eggs, not every time you cook. For most home kitchens, that might be 2 to 4 times per week. Daily use is unnecessary and can dry the wood over time, so for vegetables and bread a vinegar solution is usually enough.
Q: What type of oil should I use after sanitising my board?
A: Use a food safe mineral oil or a dedicated board oil, not olive oil or other cooking oils that can turn sticky. Apply about 5 to 10 ml to a 45x35cm board once a month, or whenever the surface looks dry or feels rough. Let it soak in for at least 20 minutes, then buff off any excess with a clean cloth.
Q: Is bamboo as safe as hardwood for cutting raw meat?
A: Yes, dense bamboo such as Moso bamboo is suitable for raw meat as long as you follow a proper sanitising routine. Many cooks like to keep one board, for example a carbonised bamboo 45x35cm, just for meat and another for fruit and vegetables. The key is prompt washing, a 1:10 bleach sanitise when needed and full drying between uses.
Recommended Deer & Oak boards for easy sanitising
If you want to put this sanitising routine into practice, it helps to start with boards that are designed for it. For most British kitchens, the Bamboo Double Pack (DNO-BCB-2PK) is a practical choice. You get one 45x35cm board for meat and fish and one 38x28cm board for vegetables and fruit, both in durable Moso bamboo that responds well to hot water cleaning and monthly oiling.
If you prefer a darker look and a slightly heavier feel, the Carbonised Bamboo Board (DNO-CBB-LG) at 45x35cm and 1.9kg works nicely as a dedicated meat board alongside a lighter bamboo or acacia board for fresh produce.
