how to maintain wooden vs plastic cutting boards

If you want your cutting boards to last 5 to 10 years, the rule is simple: wash plastic boards within 2 minutes of use and oil wooden boards every 3 to 4 weeks. That single habit, plus proper drying, prevents warping, stains and deep smells in both wooden and plastic boards.

Wooden vs plastic cutting boards: which is best to maintain?

In day to day use, plastic boards are quicker to maintain because you can put most of them in the dishwasher at 60°C. Wooden boards, like our 45x35cm Deer & Oak Large Bamboo Board at 1.8kg, need hand washing and regular oiling, but they reward you with 5 to 10 years of service if you care for them properly.

If you want low effort and are happy to replace boards every 1 to 3 years, plastic is easier. If you prefer something that looks beautiful on the worktop, is kinder to knives and can last much longer, wooden boards are worth the extra 5 to 10 minutes of care each month.

How to maintain wooden cutting boards step by step

1. Daily cleaning (after every use)

• Wash by hand within 5 minutes using warm water and a small amount of washing up liquid.
• Use a soft sponge or brush and scrub along the grain of the wood.
• Rinse thoroughly so no soap film remains on the surface.
• Dry immediately with a clean tea towel, then stand the board on its edge so air can circulate on both sides.

Never soak wooden boards in the sink and never put them in the dishwasher. A single 70°C dishwasher cycle can twist or crack a 45x35cm board as the wood swells and then dries too quickly.

2. Deep cleaning for smells and stains

For onion, garlic or raw meat smells, or light staining, use this 3 minute routine:

1. Sprinkle 1 to 2 tablespoons of coarse salt over the board.
2. Cut a lemon in half and scrub the salt into the surface with the cut side.
3. Leave for 5 minutes, then rinse with warm water and dry thoroughly.

This works especially well on bamboo and acacia boards, such as our Medium Acacia Board 38x28cm, where the natural grain helps hide light marks once cleaned.

3. Oiling wooden boards every 3 to 4 weeks

Oiling is what turns a wooden board from something that lasts 1 to 2 years into something that can last up to a decade. For an average family kitchen, oiling every 3 to 4 weeks is enough.

Use: food safe mineral oil or a specialist board oil. Avoid olive oil, sunflower oil or other cooking oils as they can turn sticky and rancid.

How to oil in 5 simple steps:

1. Make sure the board is completely dry on both sides.
2. Pour 1 to 2 teaspoons of oil onto the surface of a medium board (38x28cm) or 2 to 3 teaspoons for a large 45x35cm board.
3. Spread the oil with a lint free cloth, working in the direction of the grain, including the edges and handle cut outs if there are any.
4. Leave to absorb for at least 20 minutes, or overnight for very dry boards.
5. Wipe away any excess with a clean cloth so the surface is smooth, not greasy.

4. Extra care for carbonised and acacia boards

Carbonised bamboo and acacia are slightly denser than natural bamboo and hold oil very well. That makes them ideal if you want a board that resists water and stains.

• Carbonised bamboo like our Deer & Oak Carbonised Bamboo Board benefits from a slightly lighter oiling every 4 to 6 weeks, as the darker finish hides marks more easily.
• Acacia boards, such as the Deer & Oak acacia board set, should be oiled every 3 to 4 weeks if used daily for chopping meat and vegetables.

How to maintain plastic cutting boards properly

1. Daily cleaning

• Rinse immediately after use to stop stains from setting, especially from tomato, beetroot or curry.
• Dishwasher safe boards can go on the top rack on a 50 to 60°C cycle. Check the manufacturer’s instructions first.
• If washing by hand, use hot water, washing up liquid and a non scratch scrubber.

Plastic boards are less likely to warp in the dishwasher than wood, but cheaper thin boards can bend over time. Look for boards that are at least 1cm thick if you want them to stay flat longer.

2. Disinfecting plastic boards

For boards used with raw chicken, pork or fish, a weekly disinfect is sensible.

• Mix 1 tablespoon of unscented bleach with 1 litre of water.
• Apply to the board and leave for 2 minutes.
• Rinse thoroughly with hot water and dry upright.

Alternatively, a dishwasher cycle at 60°C or above gives similar antibacterial results, as long as the board is dishwasher safe.

3. Replacing plastic boards at the right time

Plastic boards do not benefit from oiling and usually have a shorter life. Deep grooves can trap moisture and bacteria. As a guide:

• Inspect your plastic boards every 3 months.
• If you can feel deep cuts with your fingernail, or see grey staining in the cuts that does not clean away, it’s time to replace.
• Busy family kitchens often replace plastic boards every 12 to 24 months.

Wooden vs plastic: hygiene, knives and longevity

Hygiene

• Wooden boards have a natural capillary action. Moisture and some bacteria are drawn below the surface where they dry out. Several studies have shown that bacteria counts on wood drop sharply within a few hours, as long as the board is dried properly.
• Plastic boards are non porous when new, but deep cuts can hold moisture. Regular disinfecting and timely replacement solve this.

Knife friendliness

• Wood and bamboo are gentler on knife edges, which means you can go longer between sharpening sessions. On a good board, a home cook can often keep knives sharp for 3 to 6 months with light honing.
• Hard plastics can be harsher on fine edges, especially with heavy chopping.

Longevity and value

• A well cared for 45x35cm bamboo or acacia board can last 5 to 10 years.
• A plastic board used daily may need replacing every 1 to 3 years.

If you cook most nights, a quality wooden board often works out better value over a 5 year period, even if the upfront price is slightly higher.

Who this is for and who it is not for

Ideal for:

• Home cooks who prepare food at least 3 to 4 times a week and want their boards to last 5 years or more.
• People who value natural materials like bamboo and acacia and are happy to spend 5 to 10 minutes a month on oiling.
• Families who like to keep separate boards for meat and vegetables and want clear guidance on hygiene.

Not recommended for:

• Anyone who wants to put every board in the dishwasher every time, including wood, without any hand care.
• People who replace boards every few months and are not interested in long term maintenance.
• Commercial kitchens that require colour coded plastic boards and strict chemical disinfection systems.

Product problem pairs: choosing the right board for your habits

• Problem: Your current board warps or cracks after a year.
  Solution: Choose a thicker wooden board like the Large Acacia Board 45x35cm, 2.1kg, oil it every 3 to 4 weeks and always dry it upright. The extra weight and density keep it stable.
• Problem: You cook for 3 to 5 people and run out of space when chopping.
  Solution: A 45x35cm Large Bamboo Board gives enough room for several piles of ingredients. At 1.8kg it is still easy to move to the sink for washing.
• Problem: You want one board for prep and one for serving.
  Solution: Use a natural Medium Bamboo Board 38x28cm for daily chopping and a Carbonised Bamboo Board 45x35cm for serving, as the darker finish hides knife marks and looks smart on the table.
• Problem: You share a small kitchen and need flexible options.
  Solution: The Bamboo Double Pack combines a 45x35cm and a 38x28cm board, giving you a meat board and a vegetable board that stack neatly and are maintained in exactly the same way.
