If you want your cutting boards to last 5 to 10 years, the simplest rule is this: wash plastic boards hot and often, and oil wood boards every 4 weeks. Wood needs drying time and oil, plastic needs heat and regular replacement. Once you know that, choosing how to maintain wood vs plastic cutting boards becomes very straightforward.
Wood vs plastic cutting boards: what actually needs doing?
Wood and plastic boards fail in different ways, so their care routines are different.
Wood boards (bamboo or acacia)
- Daily: Wipe, wash in warm soapy water, rinse, stand upright to air dry.
- Weekly: Disinfect with white vinegar or a 3% hydrogen peroxide rinse.
- Every 3 to 4 weeks: Oil with food safe mineral oil. For a 45x35cm board this takes about 10 ml of oil and 10 minutes of your time.
- Every 12 months: Light sand and re oil if the surface looks dry or rough.
Plastic boards
- After each use: Hot soapy wash or dishwasher cycle at 60°C if the board is dishwasher safe.
- Weekly: Bleach solution clean for raw meat boards (for example 1 tablespoon thin bleach in 1 litre of water).
- Every 12 to 24 months: Replace when deep knife grooves stay stained or cannot be scrubbed clean.
If you want less work day to day, plastic is easier. If you want a board that can last 5 to 10 years and is kinder to your knives, a well oiled wood board wins.
Step by step: how to maintain wood cutting boards
At Deer & Oak we pre oil every bamboo and acacia board so you can start using it straight away. To keep that finish, follow this simple routine.
1. Cleaning after each use
- Scrape off food with a plastic scraper or the back of a knife.
- Wash by hand with warm water and a mild washing up liquid.
- Rinse and dry immediately with a clean tea towel.
- Stand the board on its side so air can circulate on both faces.
Never put wood boards in the dishwasher, never soak them in the sink and do not leave them flat on a wet surface. A 45x35cm board that sits in water for 30 minutes can cup or warp permanently.
2. Monthly oiling routine
For bamboo and acacia, a regular oiling keeps water out and stops cracking.
- Make sure the board is completely dry. Leave it standing overnight if needed.
- Pour about 2 teaspoons (10 ml) of food safe mineral oil onto the surface.
- Spread with a lint free cloth in the direction of the grain, including the edges and juice groove if there is one.
- Leave for 20 to 30 minutes, then wipe away any excess.
- Repeat on the other side.
For a heavily used board, such as a butcher style block, oiling every 2 to 3 weeks is sensible. A well oiled board feels silky, not rough, and repels water drops instead of letting them soak in.
3. Dealing with smells and stains
- Odours (onion, garlic, fish): Sprinkle 1 tablespoon of coarse salt, rub with half a lemon, leave 5 minutes, then rinse and dry.
- Stains (beetroot, turmeric): Make a paste of bicarbonate of soda and water, spread over the mark, wait 15 minutes, scrub gently and rinse.
On our Bamboo Double Pack, most everyday stains lift in under 5 minutes with this method, especially on the lighter Moso bamboo surface.
4. Annual refresh
If your board is 2 to 3 years old and looks tired, a quick refresh can add several more years of use.
- Sand lightly with 240 grit sandpaper to remove raised grain and knife marks.
- Wipe away dust with a slightly damp cloth and let the board dry fully.
- Apply 2 thin coats of mineral oil, 30 minutes apart.
We do this process in the workshop on our Carbonised Bamboo Board and see boards come back to a deep, even colour in under an hour.
How to maintain plastic cutting boards safely
Plastic boards do not need oil but they do need heat and regular replacement to stay hygienic.
1. Daily wash
- Rinse off scraps immediately after use.
- Dishwasher safe boards can go through a full cycle at 60°C.
- If hand washing, use the hottest water you can comfortably handle and a stiff brush.
Plastic boards are handy for raw chicken and seafood because you can use strong detergents and hotter water than you would on wood.
2. Weekly deep clean
- For raw meat boards, soak for 2 minutes in a mild bleach solution (about 1 tablespoon thin bleach per 1 litre of water).
- Rinse very well and air dry upright.
Keep separate boards for raw meat, cooked food and vegetables. Colour coding helps, or you can mark the underside with a permanent marker.
3. When to throw a plastic board away
Unlike wood, plastic does not self heal. Deep knife grooves stay open and can trap food. Replace a plastic board when:
- There are visible gouges you can feel with a fingertip.
- Stains do not lift after a bleach soak.
- The surface has warped and no longer sits flat.
For most home cooks this happens every 12 to 24 months if the board is used daily. At that point, a thick wood board becomes more economical over time.
Wood vs plastic: which is kinder to your knives and more hygienic?
Knife friendliness
- Wood (especially acacia and bamboo) is gentler on knife edges. On our 45x35cm Large Bamboo Board we see less visible edge wear after 6 months of daily chopping compared with a thin plastic mat.
- Hard plastic can feel "glass like" and will dull a fine edge more quickly.
Hygiene
- Studies show that bacteria can sink into wood fibres and die off as the board dries, which is why thorough drying is so important.
- Plastic can be scrubbed and bleached more aggressively, which is useful for raw meat, but deep grooves stay contaminated.
In a typical British kitchen, many cooks use a combination: a large wood board for vegetables, bread and carving, and a smaller plastic board reserved for raw meat and fish.

- People who are happy to spend 10 minutes once a month oiling a wood board.
- Anyone who uses sharp knives and wants to protect the edge from hard worktops.
- Hosts who like boards that can double as serving platters for cheese, bread or roast meats.
Not recommended for
- Those who put everything in the dishwasher and never want to hand wash.
- Commercial kitchens that must meet strict plastic only hygiene rules.

FAQ
Q: How often should I oil my wood cutting board?
A: For most Deer & Oak bamboo and acacia boards, oiling every 3 to 4 weeks is enough if you use them daily. If the surface looks dry, turns pale in patches or absorbs water instantly, bring oiling forward to every 2 weeks until the wood is saturated again.
Q: Can I use the same board for meat and vegetables?
A: You can if you wash carefully, but it is safer to keep raw meat on a separate board. Many customers pair a wood board for vegetables with a smaller plastic board for raw chicken and fish, or use our Bamboo Double Pack so one board can be reserved for cooked food only.
Q: Is bamboo better than plastic for hygiene?
A: Bamboo is naturally less porous than many soft woods and, when kept dry between uses, tests show that bacteria die off quite quickly in the fibres. Plastic can be bleached and dishwashed at high temperatures, but once it has deep cuts those grooves can hold contamination even after washing.
Q: Why is my wood board warping or cracking?
A: Warping usually comes from uneven moisture, for example soaking one side or drying the board flat on a hot surface. Cracks often appear when a board is left un oiled for several months. To prevent both, avoid soaking, dry upright on edge and oil the board every month with food safe mineral oil.
Closing thoughts and recommended boards
If you want the lowest effort, a plastic board you can dishwash and replace every 1 to 2 years is simple. If you prefer something that looks good on the worktop, is kinder to your knives and can last 5 to 10 years with light care, a wood board is worth the small amount of maintenance.
For most homes, we recommend starting with the Large Bamboo Board 45x35cm (1.8 kg, £34.99) as your main prep surface, paired with a slim plastic board for raw meat. If you often cook for family or like to serve at the table, the Bamboo Double Pack 45x35cm + 38x28cm from our chopping board collection gives you two sizes that are easy to care for with the same monthly oiling routine.
