If you want your cutting boards to last 5 to 10 years, the simplest rule is this: wash plastic within 5 minutes of use and oil wooden boards every 4 to 6 weeks. That single habit for each material will prevent deep staining, warping and most hygiene problems.
Wooden vs plastic cutting boards: what actually works best?
For everyday home cooking, a mix of one wooden board and one plastic board usually works best. Use a wooden board for bread, fruit, vegetables and cooked foods, and a plastic board for raw meat and fish. Wooden boards such as the Deer & Oak Large Bamboo Board (45x35cm, 1.8kg) can last 8 to 10 years with oiling, while a plastic board of a similar size usually needs replacing every 2 to 4 years once the surface is deeply scarred.
How to maintain a wooden cutting board
1. Daily cleaning in under 2 minutes
- Wipe off crumbs and scraps straight after use.
- Wash by hand with warm water and a small amount of washing up liquid.
- Scrub along the grain for 20 to 30 seconds.
- Rinse quickly and dry with a clean tea towel.
- Stand the board upright so both faces can dry within 2 to 3 hours.
Never soak a wooden board, never put it in the dishwasher and avoid leaving it flat on a wet surface. Soaking for just 30 minutes can raise the grain and start minor warping, especially on larger boards like our XL bamboo board.
2. Monthly deep clean and deodorise
Every 2 to 4 weeks, or after strong smelling foods such as garlic, onions or fish:
- Sprinkle 10 to 15g of coarse salt over the surface.
- Cut a lemon in half and scrub the salt into the board for 1 to 2 minutes.
- Leave for 5 minutes to help lift stains and odours.
- Rinse quickly with warm water and dry thoroughly.
This is gentle enough for all Deer & Oak wooden boards, including our 2.1kg Large Acacia Board, but tough on lingering smells.
3. Oiling schedule that actually works
Wood is a natural material that dries out. Without oil it can crack within 1 to 3 years. With oil, it can last up to a decade.
For most UK kitchens:
- First 3 months: oil every 2 weeks.
- After 3 months: oil every 4 to 6 weeks.
- In very dry, centrally heated homes: check every 3 to 4 weeks.
Use food safe mineral oil or a dedicated board conditioner. Avoid olive oil or other cooking oils, as they can turn sticky or rancid within a few weeks.
4. How to oil a wooden board in 10 minutes
- Make sure the board is completely dry, ideally air dried for at least 8 hours.
- Pour 5 to 10ml of oil onto the surface.
- Spread with a lint free cloth in the direction of the grain.
- Coat all sides and edges, including any juice grooves.
- Leave to soak for 20 to 30 minutes.
- Wipe off any excess so the surface is not greasy.
- Stand upright and leave overnight before use.
5. When to sand or replace a wooden board
Inspect your board every 3 months. If you see shallow knife marks, oiling is enough. If you see deep cuts more than 1mm deep that trap food, lightly sand with 120 then 240 grit paper, wipe clean, then oil twice. If the board is split through or badly warped so it rocks more than 2 to 3mm on the worktop, it is time to replace it.
How to maintain a plastic cutting board
1. Cleaning straight after use
Plastic boards are less sensitive to water but they can hold odours and stains if left dirty for too long.
- Rinse within 5 minutes of use, especially after raw meat or fish.
- Scrub with hot water and washing up liquid for 30 seconds.
- Rinse and air dry upright or in a rack.
- If dishwasher safe, use a full cycle at 60 to 70°C, top rack if recommended.
If you can still smell raw meat after washing, repeat the wash or use a diluted bleach solution as described below.
2. Disinfecting safely
Every 1 to 2 weeks, or after cutting raw chicken or pork, disinfect your plastic board:
- Mix 1 tablespoon (about 15ml) of unscented household bleach with 1 litre of cold water.
- Apply enough solution to cover the board surface.
- Leave for 2 minutes for everyday use, up to 5 minutes after raw meat.
- Rinse thoroughly with clean water and let the board dry fully.
Do not use this method on wooden boards, as bleach can dry and discolour wood within a few uses.
3. Managing stains and odours
- For tomato or beetroot stains: scrub with a paste of bicarbonate of soda and water, leave for 10 minutes, then rinse.
- For strong smells: rub with half a lemon, leave for 5 minutes, then wash as normal.
If stains remain after two or three treatments, they are usually cosmetic. If the surface is also heavily scored, it is safer to replace the board.
4. When to replace a plastic board
Plastic boards do not benefit from oiling or sanding, so replacement is the main maintenance tool. As a guide, check every 6 months. Replace if:
- The surface has deep cuts that are hard to clean with a brush.
- The board is warped more than 3mm and rocks on the worktop.
- The surface remains stained and rough after cleaning.
In a busy family kitchen that cooks daily, a plastic board often needs replacing every 2 to 4 years. In a lighter use kitchen, 4 to 6 years is common.
Wooden vs plastic: hygiene, knives and lifespan
Hygiene
- Wooden boards naturally absorb small amounts of moisture. Studies show many bacteria die off within a few hours on well maintained hardwood boards. Regular washing and oiling are still essential.
- Plastic boards are easy to disinfect with bleach or in the dishwasher. Once heavily scarred, they can hold bacteria in the cuts, even after washing.
Knife care
- Wooden surfaces such as bamboo and acacia are kinder to knife edges and can extend the time between sharpening by 20 to 30 percent compared with very hard plastic or glass.
- Plastic boards are usually softer than glass but can still dull fine edges faster than a well oiled wooden surface.
Lifespan
- A well cared for wooden board such as the Deer & Oak Carbonised Bamboo Board (45x35cm, 1.9kg) can last 8 to 10 years with oiling every 4 to 6 weeks.
- A plastic board of similar size typically lasts 2 to 4 years in a busy kitchen before deep cuts and stains make replacement sensible.

Product problems our boards are designed to solve
-
Problem: Plastic boards warping in the dishwasher
Our 45x35cm Large Bamboo Board and Large Acacia Board are designed for hand washing. At 1.8kg and 2.1kg they sit flat on the worktop and resist the twisting that lighter plastic often suffers after repeated hot washes. -
Problem: Knives dulling quickly on hard plastic
The natural grain of our Moso bamboo and acacia boards offers a slightly forgiving surface that is kinder to knife edges, especially on chef’s knives between 18 and 25cm. -
Problem: Short lifespan of cheap boards
Where a low cost plastic board might last 2 years, our pre oiled bamboo boards, such as the Carbonised Bamboo Board, are built for 8 to 10 years of use with simple oiling. -
Problem: Not enough surface space
The 45x35cm size on our Large Bamboo, Carbonised Bamboo and Large Acacia boards gives a 1575cm² work area. That is enough space to slice a full loaf or prep vegetables for a family meal without crowding.

FAQ
Q: How often should I oil a wooden cutting board?
A: For the first 3 months, oil your wooden board every 2 weeks to build up protection, then move to every 4 to 6 weeks. In a very dry home or if the board looks pale and feels rough, check it every 3 to 4 weeks and oil sooner if needed.
Q: Is wood or plastic more hygienic for cutting meat?
A: For raw meat and fish, a dedicated plastic board that you can disinfect with bleach or put in the dishwasher is usually more practical. Many people then keep a separate wooden board for bread, fruit and vegetables to protect knives and reduce cross contamination.
Q: Can I put a wooden cutting board in the dishwasher?
A: No, wooden boards should not go in the dishwasher. The high heat and long soak can cause warping and cracks within a few cycles, especially on larger 45x35cm boards. Always wash wood by hand with warm soapy water and dry upright.
Q: When should I replace my cutting board?
A: Replace any board when it has deep cuts that are hard to clean, when it rocks on the worktop by more than a few millimetres or when it is cracked through. For plastic this is often every 2 to 4 years, while a well maintained wooden board can last up to 10 years.
