what oil is best for wooden cutting boards

If you want your wooden cutting board to last 5 to 10 years, the best oil to use is 100% food grade mineral oil applied in a thin coat every 4 to 6 weeks. For extra protection, pairing mineral oil with a natural wax conditioner keeps boards like our 45x35cm Deer & Oak Large Bamboo Board and 45x35cm Large Acacia Board sealed, hydrated and less likely to crack.

Why mineral oil is best for wooden cutting boards

When people ask “what oil is best for wooden cutting boards?”, they usually want three things: safety, long life and easy care. Food grade mineral oil ticks all three.

• It doesn’t go rancid: Unlike olive or sunflower oil, mineral oil is stable. It won’t smell after 3 to 6 months.
• It soaks in deeply: The molecules are small enough to penetrate bamboo and hardwood fibres.
• It’s food safe: Look for food grade or butcher block mineral oil on the label.
• It’s neutral: No flavour, no scent, no colour to stain your board.

At Deer & Oak, every pre oiled board, from our Carbonised Bamboo Board to our acacia range, is treated with food safe mineral oil so you can top up at home with the same type of oil.

Good, better, best: oils you can and can’t use

Best choice: food grade mineral oil

Use this for: Everyday maintenance on bamboo, acacia, beech and other hardwood boards.

• Apply 5 to 10 ml to a 45x35cm board
• Let it soak for 20 to 30 minutes
• Buff dry with a clean cotton cloth

Excellent upgrade: mineral oil plus wax conditioner

If you want extra water resistance, use a conditioner that combines mineral oil with beeswax or plant wax.

• Use every 2 to 3 months on top of regular oiling
• Helps boards used daily for chopping meat, veg and bread
• Ideal for heavy boards like our 2.1kg Large Acacia Board

Conditioners that can work, but with care

Some natural oils are sometimes used, but each has limits:

• Walnut oil: Can cure and harden, but not suitable if anyone has a nut allergy.
• Tung oil (pure): Hard drying finish, but curing can take several days and you must avoid additives.
• Fractionated coconut oil: More stable than normal coconut oil, but always check that it’s food grade and non scented.

Oils you should avoid on cutting boards

Some oils seem tempting because they are already in the kitchen, but they cause problems within months:

• Olive oil: Turns sticky and rancid, leaves a smell and gummy surface.
• Sunflower, rapeseed, vegetable oil: All oxidise and go off, especially in warm kitchens.
• Sesame, peanut and other aromatic oils: Strong flavours and higher risk of allergies.

If a bottle is sold as cooking oil, it usually isn’t the best oil for wooden cutting boards. Stick to products clearly labelled for boards, butcher blocks and worktops.

How to oil a wooden cutting board in 5 simple steps

Here’s a clear routine you can use on any of our boards, from the 38x28cm Medium Bamboo Board to the 45x35cm Carbonised Bamboo Board:

1. Clean the board
   Wash with warm water and a small amount of mild washing up liquid. Rinse, then dry with a towel.
2. Let it dry fully
   Stand the board on its side and let it air dry for at least 8 hours, ideally overnight.
3. Apply mineral oil
   Pour a thin line of oil, about 5 ml for a 38x28cm board or 10 ml for a 45x35cm board, directly onto the surface.
4. Spread evenly
   Use a clean cloth or paper towel to work the oil in, covering both sides and all four edges. Pay extra attention to knife scars.
5. Rest and buff
   Leave the board flat for 20 to 30 minutes. If any oil is still sitting on the surface, buff it off so the board feels dry, not greasy.

For a very dry or new board, repeat the oiling step 2 or 3 times on day one. Our pre oiled Deer & Oak boards arrive with this initial saturation already done, so you only need to maintain the finish.

How often should you oil your board?

How often you should oil depends on how you use your board and what it’s made from:

• Daily use, heavy chopping like a butcher’s block: Every 3 to 4 weeks.
• Regular home cooking once a day: Every 4 to 6 weeks.
• Occasional use once or twice a week: Every 2 to 3 months.

Bamboo is naturally denser than many hardwoods, so our Moso Bamboo boards hold oil well. Acacia is slightly more open grained, so the Large Acacia Board may appreciate oiling closer to the 4 week mark if you use it daily.

A simple test: drip a teaspoon of water onto the board. If it beads tightly, the oil is still doing its job. If it spreads out and darkens the wood within 10 seconds, it’s time to re oil.

Why pre oiled boards make care easier

Starting with a well prepared board makes the whole process easier. Deer & Oak boards are pre treated with food safe oil so the wood is protected from day one.

Here’s how a well oiled board helps in daily cooking:

• Less warping: Even saturation reduces the risk of cupping when one side gets wet.
• Better hygiene: A sealed surface is less likely to absorb raw meat juices.
• Less staining: Tomatoes, beetroot and turmeric are less likely to leave deep marks.
• Longer life: With regular oiling, a quality board can last 5 to 10 years or more.

If you’d like a ready to go option, our Bamboo Double Pack includes one 45x35cm board and one 38x28cm board, both pre oiled and ready for daily use.
