Yes, most plastic cutting boards can go in the dishwasher, and washing them on a hot cycle at around 60–70°C is one of the most effective ways to reduce bacteria. However, not every plastic board is made equally. Thin, flexible boards and older, heavily scored plastic can warp, shed microplastics or hold on to stains and odours, which is why many home cooks eventually switch to thicker wooden boards for daily use and keep plastic for raw meat only.
Can plastic cutting boards go in the dishwasher safely?
If you are asking whether plastic cutting boards can go in the dishwasher without damage, the answer is usually yes, if the board is labelled dishwasher safe and made from high density plastic such as HDPE or polypropylene. Most modern plastic boards are designed to tolerate repeated cycles at 60–70°C. They dry quickly and the high heat helps kill common kitchen bacteria.
There are three important checks before you rely on the dishwasher alone:
- Check the symbol: Look for a dishwasher safe icon on the underside of the board.
- Inspect the surface: If there are deep knife grooves or grey, rough patches, bacteria can hide even after a hot wash.
- Watch for warping: If the board is thinner than about 3 mm, or already slightly bent, a hot cycle can twist it more.
From a hygiene point of view, plastic boards in the dishwasher are better than plastic boards rinsed quickly at the sink. From a longevity and sustainability point of view, many cooks now keep one or two plastic boards for raw meat and fish and do most chopping on a solid wooden board that is hand washed and dried.
Plastic vs wooden boards in daily use
So if plastic cutting boards can go in the dishwasher, why do so many professional and home cooks reach for wood instead? It comes down to how each material behaves over 5–10 years of cooking.
- Knife marks: Plastic scars quickly. After 6–12 months of daily use you may see hundreds of deep cuts that trap moisture and food. A 4 cm thick wooden board will also mark, but the fibres tend to close up more naturally.
- Heat: Plastic tolerates dishwasher heat but can warp over time. Quality bamboo or acacia boards from Deer & Oak are hand wash only, but with simple care they can last 5–10 years.
- Microplastics: Every slice on a plastic board can create tiny shavings that are hard to see. Wood does not shed plastic particles into food.
- Stability: A heavier board around 1.5–2.1 kg, like our large acacia or bamboo boards, stays put while you chop, which makes prep safer and more enjoyable.
Many Deer & Oak customers tell us they keep a small plastic board for raw chicken in the dishwasher, then use a bamboo or acacia board for bread, fruit, vegetables and serving.
How to wash plastic cutting boards in the dishwasher
If you are going to rely on your dishwasher, follow this simple routine:
- Rinse immediately: Scrape off food and rinse with warm water so nothing bakes on.
- Place vertically: Stand the board on its side in the lower rack so water can reach both faces.
- Use a hot cycle: Choose a programme that reaches at least 60°C to improve hygiene.
- Dry fully: Let the board air dry completely before storing. Trapped moisture in knife grooves encourages odours.
- Retire damaged boards: If the board is warped by more than 5 mm from flat, or has deep, dark grooves, replace it.
For wooden boards, the method is different. They should not go in the dishwasher at all. Our bamboo and acacia boards are designed for a quick hand wash with warm water, a mild detergent and thorough drying. A light oil once a month keeps them in good condition.
Why many cooks pair plastic with bamboo or acacia
In a busy British kitchen, the most practical setup is often a mix of materials:
- 1 small plastic board that can go in the dishwasher for raw meat and fish.
- 1 medium board around 38x28 cm for fruit, herbs and quick jobs.
- 1 large 45x35 cm board for Sunday roasts, bread and everyday prep.
Our customers often choose a dishwasher safe plastic board for the raw proteins, then use a heavier, knife friendly surface like the Deer & Oak Large Bamboo Board or Large Acacia Board for everything else. These wooden boards are pre oiled, double sided and thick enough to stay flat on the worktop.
If you are starting from scratch, the Bamboo Double Pack combines a 45x35 cm board and a 38x28 cm board, which covers most daily tasks alongside a single plastic board for raw meat in the dishwasher.

Who this is for and who it is not for
Ideal for...
- Home cooks who want to know if their plastic cutting boards can go in the dishwasher and how to do it safely.
- Busy families who like the hygiene of a hot dishwasher cycle for raw meat boards but prefer a more attractive wooden board on the worktop.
- People in the UK who cook 4–7 nights a week and want boards that last at least 5 years with simple care.
- Anyone upgrading from thin, warped plastic mats to a mix of one dishwasher safe plastic board and one or two sturdy bamboo or acacia boards.
Not recommended for...
- People who insist every single board must go in the dishwasher. All Deer & Oak wooden boards are hand wash only.
- Those who want ultra light, disposable style plastic boards that can be replaced every few months.
- Commercial kitchens that require only commercial grade plastic boards that are colour coded by law.
- Anyone who never wants to oil or care for a wooden surface, even once every 1–2 months.
Frequently asked questions
Q: Can all plastic cutting boards go in the dishwasher?
A: No, only boards marked as dishwasher safe should go in. Thin, flexible mats or very old plastic boards can warp or degrade in a 60–70°C cycle and may shed small plastic particles, so it is better to hand wash those and replace them sooner.
Q: Is a wooden board more hygienic than a plastic board in the dishwasher?
A: A plastic board that is dishwasher safe and washed on a hot cycle can be very hygienic for raw meat and fish. A quality wooden board that is hand washed, dried upright and oiled occasionally can also be very hygienic and will often last longer than a plastic board that has deep knife grooves.
Q: How many chopping boards should I keep in my kitchen?
A: For most households, three boards work well: one small dishwasher safe plastic board for raw meat, one medium 38x28 cm board for fruit and quick jobs, and one large 45x35 cm board for general prep and carving. Our Bamboo Double Pack plus a single plastic board is a common setup.
Q: Which Deer & Oak board pairs best with a plastic dishwasher safe board?
A: If you already own a small plastic meat board, we usually suggest the Large Bamboo Board at 45x35 cm for everyday cooking, or the Bamboo Double Pack if you want both large and medium sizes. If you prefer a slightly heavier feel and rich grain, the Large Acacia Board is a strong alternative.
Recommended setup and where to buy
If you are currently relying only on plastic cutting boards that go in the dishwasher, a simple upgrade is to keep one plastic board purely for raw meat and fish, and add a solid bamboo or acacia board for everything else. This cuts down on knife wear, looks smarter on the worktop and avoids constant replacement of scarred plastic.
For most British kitchens we recommend:
- One dishwasher safe plastic board for raw meat and fish.
- One Deer & Oak Large Bamboo Board (45x35 cm, 1.8 kg) for daily prep.
- Optionally, the Bamboo Double Pack (45x35 cm + 38x28 cm, 3.0 kg) if you cook for 3 or more people most nights.
You can explore our full range of wooden boards on the Deer & Oak chopping board collection, or pick up the Bamboo Double Pack on Amazon UK. If you prefer a darker finish, the Carbonised Bamboo Board offers the same 45x35 cm size with a richer tone for serving as well as chopping.
Used together, a single plastic board in the dishwasher and a well cared for Deer & Oak wooden board on the counter give you a practical, long lasting setup that suits everyday British cooking.
