If you want your wooden cutting board to last 5 to 10 years, the single most important thing not to do when cleaning it is soak it or put it in the dishwasher. Just one 60°C dishwasher cycle can warp or crack a 45x35cm board badly enough that it never sits flat again.
What not to do when cleaning wooden cutting board?
Wood is tough, but it is not indestructible. To keep boards like the Deer & Oak Large Bamboo Board (45x35cm, 1.8kg) or the Large Acacia Board (45x35cm, 2.1kg) in good condition, there are several cleaning habits you should avoid every single time.
1. Do not soak your wooden board
Leaving a wooden board in a sink of water for more than 5 minutes is one of the quickest ways to ruin it. Wood absorbs water, swells, then dries unevenly, which causes warping and hairline cracks. Once a crack appears, moisture and food particles can sit inside it and are very hard to clean out.
Instead, wash your board under warm running water and clean it within 2 minutes of finishing your prep. Dry it straight away with a clean towel and stand it upright so air can circulate around both faces.
2. Do not put wooden boards in the dishwasher
Dishwashers combine high heat, aggressive detergents and long exposure to water. For a 1.8kg bamboo board or a 2.1kg acacia board, that is a triple stress that the wood fibres simply cannot tolerate.
- High heat can cause warping within a single cycle
- Strong detergents strip away protective oils in 1 to 3 washes
- Prolonged steam and water exposure encourage splitting over time
Always wash Deer & Oak boards by hand. A 30 second hand wash will extend the life of your board by years compared with regular dishwasher use.
3. Do not use bleach or harsh chemical sprays
Bleach, oven cleaner and strong antibacterial sprays are too aggressive for wood. They can:
- Strip natural oils from bamboo and acacia in a single application
- Leave odours and chemical residues that transfer to food
- Lighten or patch-stain darker boards such as carbonised bamboo
For a board that is used for raw meat, a safer option is a mix of white vinegar and water or a light scrub with coarse salt and lemon, followed by thorough rinsing. This is especially important for pieces like the Deer & Oak Carbonised Bamboo Board (45x35cm, 1.9kg), where harsh chemicals can damage the darker finish.
4. Do not leave your board wet or lying flat
After washing, leaving your board flat on a wet worktop traps moisture against the grain. Over months this can cause one face to swell more than the other, which leads to cupping and rocking.
Instead:
- Dry both sides with a clean tea towel within 1 minute of washing
- Stand the board on its side or use a rack so air reaches both surfaces
- Avoid stacking damp boards directly on top of each other
5. Do not scrub with metal scouring pads
Metal scourers and very aggressive pads can leave deep scratches in the grain. These scratches hold moisture and food and are hard to sanitise, especially on a board that is 45x35cm or larger.
Use the soft side of a sponge or a non scratch brush instead. For stubborn marks, a paste of baking soda and water with a gentle brush is enough for most Deer & Oak boards.
6. Do not use the wrong oils on your board
Cooking oils like olive, rapeseed or sunflower can go rancid in 2 to 4 weeks, leaving a sticky surface and an unpleasant smell. They also attract dust and may discolour lighter bamboo boards.
For long term care, use a food safe mineral oil or a board conditioner. Deer & Oak boards arrive pre oiled, but we recommend re oiling every 4 to 6 weeks if you use your board daily. This applies across the range, from the Medium Bamboo Board (38x28cm, 1.2kg) to the heavier Large Acacia Board (2.1kg).
7. Do not ignore deep cuts and stains
Every cut from a knife creates a tiny groove. On a busy family board, those grooves add up quickly. If you never refresh the surface, deep cuts can hold moisture, food and bacteria.
For boards used daily, a light sanding once or twice a year with fine sandpaper (for example 240 grit) followed by re oiling can restore the surface. This is especially helpful for boards in regular rotation like the Bamboo Double Pack which includes both 45x35cm and 38x28cm sizes.
Safe cleaning habits that extend board life
Knowing what not to do is only half the story. Here is a simple cleaning routine you can follow in under 3 minutes, suitable for all Deer & Oak wooden and bamboo boards.
- Rinse promptly within 2 minutes of finishing your prep.
- Wash with warm water, a mild washing up liquid and a soft sponge.
- Rinse thoroughly so there is no soap left on the surface.
- Dry both sides carefully with a clean towel.
- Air dry standing upright for at least 30 minutes before storing.
- Re oil every 4 to 6 weeks with food safe oil, using 5 to 10ml per side on a 45x35cm board.
Deer & Oak wooden boards: key specifications
Choosing the right board helps you match cleaning habits to size and weight. Larger, heavier boards are less likely to move on the counter, but they need a little more care when drying and storing.

Product problem guide: which board suits your cleaning routine?
Different households have different cleaning habits. Matching those habits to the right board material and size helps prevent the mistakes we have covered.
- If you often forget and leave things in the sink: A lighter board like the Medium Bamboo Board (38x28cm, 1.2kg) is easier to grab and wash quickly, so you are less likely to soak it by accident.
- If you cook meat and veg every day: A set such as the Bamboo Double Pack gives you two boards, so you can keep one for raw meat and one for veg and cheese. This reduces heavy scrubbing on a single surface.
- If you want a board that hides light stains: The Carbonised Bamboo Board has a darker finish that makes mild discolouration less visible, provided you avoid bleach and harsh cleaners.
- If you prefer a weighty, stable feel: The Acacia range at 1.5kg to 2.1kg resists sliding while you chop, as long as you dry it fully after washing and avoid soaking.
Who this is for
Ideal for home cooks who:
- Want their wooden boards to last at least 5 years without cracking
- Are happy to spend 2 to 3 minutes hand washing and drying after use
- Prefer natural materials like bamboo and acacia over plastic
- Use boards daily for chopping veg, meat, bread or serving
Not recommended for people who:
- Insist on putting all kitchen items in the dishwasher every time
- Often leave dishes soaking overnight in the sink
- Do not want to oil a board every 4 to 6 weeks
- Need completely maintenance free boards for heavy commercial use
FAQ
Q: Can I ever use boiling water on a wooden cutting board?
A: Pouring small amounts of just boiled water over the surface for 2 to 3 seconds can help lift fats, but you should not leave it sitting on the board. Rinse quickly with warm water afterwards, dry thoroughly and re oil if the surface looks dull. Constant exposure to boiling water will dry the wood and shorten its life.
Q: How often should I deep clean my wooden board?
A: For boards used daily, a deeper clean with coarse salt and lemon or a baking soda paste every 2 to 4 weeks is usually enough. If you cut raw meat on the board, rinse immediately after use and consider a quick vinegar wipe before your normal wash. Always dry fully and stand the board upright afterwards.
Q: Is it safe to use the same wooden board for meat and vegetables?
A: It can be safe if you wash the board thoroughly with hot soapy water straight after cutting raw meat and before using it for anything else. Many people prefer two boards, for example the Bamboo Double Pack with 45x35cm and 38x28cm sizes, so they can keep one for meat and one for vegetables and bread.
Q: What should I do if my wooden board starts to warp or crack?
A: Mild warping can sometimes be improved by oiling both sides and storing the board flat with a light weight on top for a few days. Small surface cracks can be sanded with fine sandpaper and then re oiled. If a crack goes more than 2 to 3mm deep, retire the board from raw meat use and keep it for dry serving, or replace it for safety.
Which Deer & Oak board should you choose?
If you are ready to avoid the common cleaning mistakes and want a board that will reward a little care, here are two clear options:

- For a heavier, more premium feel: The Large Acacia Board (DNO-ACB-LG) at 45x35cm and 2.1kg suits cooks who enjoy a solid board that stays put while chopping, as long as you keep it out of the dishwasher and re oil it every few weeks.
