How to deep clean wooden cutting board with baking soda?

If you want to know how to deep clean wooden cutting board with baking soda, the simplest method is to scrub 2 tablespoons of baking soda into the board for 2 to 3 minutes, leave it for 5 minutes, then rinse and dry upright for at least 12 hours. Done properly once a month, this routine can help a quality board last 5 to 10 years.

Why baking soda works on wooden boards

Baking soda is mildly alkaline and gently abrasive. On a wooden or bamboo cutting board it helps in three clear ways:

• Lifts stains from foods like beetroot, turmeric and berries
• Neutralises odours from garlic, onion and raw meat juices
• Removes greasy residue without stripping the wood when used correctly

Unlike bleach or harsh detergents, baking soda does not usually damage the natural fibres of acacia or bamboo when you rinse it thoroughly and dry the board properly.

Step by step: how to deep clean wooden cutting board with baking soda

Use this method on solid wooden or bamboo boards such as the Deer & Oak Large Bamboo Board at 45x35cm or our Large Acacia Board at 45x35cm. Avoid using it on laminated or cracked boards that already need replacing.

1. Quick pre clean (30 to 60 seconds)

1. Scrape off food: Use a scraper or blunt knife to remove any stuck bits. Work across the grain, not along it.
2. Rinse with warm water: 20 to 25°C tap water is ideal. Avoid very hot water that can warp the board.
3. Mild soap if needed: A drop of gentle washing up liquid is fine for greasy residue. Rinse well.

2. Sprinkle baking soda (about 2 tablespoons)

1. Place the board flat on a stable surface.
2. Sprinkle 1 to 2 tablespoons (about 15 to 30 grams) of baking soda evenly over the surface you want to deep clean.
3. For a Large Bamboo Board at 45x35cm, 2 tablespoons gives good coverage.

3. Activate with water or vinegar

You have two good options, depending on how dirty the board is:

• Standard deep clean: Drip 2 to 3 tablespoons of warm water over the baking soda until it forms a spreadable paste.
• Extra deodorising: For strong odours, use a 50:50 mix of white vinegar and water instead of water alone. About 3 tablespoons total liquid is usually enough.

Avoid soaking the board. You want a paste, not a puddle.

4. Scrub for 2 to 3 minutes

1. Use a clean dish brush, soft bristle scrub brush or a cut lemon half as a natural scrubber.
2. Scrub in small circles, working with the grain of the wood.
3. Pay extra attention to knife grooves, juice channels and the area where you usually cut meat or onions.
4. Continue for 2 to 3 minutes on each side you use for food.

For boards like the Deer & Oak Carbonised Bamboo Board at 45x35cm, focus on the main cutting area to protect the darker finish while still lifting stains.

5. Rest for 5 minutes

Leave the baking soda paste on the board for 5 minutes. This contact time helps it draw out odours and stains without over drying the fibres.

• Do not exceed 10 minutes, especially on lighter bamboo, as it can look slightly chalky if left too long.
• If any area dries out, add a teaspoon of water and gently re spread.

6. Rinse thoroughly (30 to 60 seconds)

1. Rinse under warm running water until you can no longer feel any grainy baking soda.
2. Run your hand over the surface; it should feel smooth, not gritty.
3. Repeat on the other side if you use it for food as well.

Never soak the board in a sink of water and never put it in a dishwasher. Both can cause warping or cracks in as little as a few months.

7. Dry upright for at least 12 hours

1. Pat the board dry with a clean tea towel.
2. Stand it upright on its edge or in a rack so air can reach both sides.
3. Leave for at least 12 hours, ideally overnight. For thicker boards, 18 to 24 hours is safer.

Proper drying is as important as the cleaning itself. A well dried 2.1kg acacia board will stay flatter and resist splitting for many more years.

8. Re oil after deep cleaning

Baking soda removes grime but can also strip a little of the protective oil from the surface. Once the board is fully dry:

1. Apply 1 to 2 teaspoons of food safe mineral oil or board conditioner to each side.
2. Spread with a lint free cloth, working with the grain.
3. Leave to soak for 20 to 30 minutes, then wipe off any excess.

For regularly used boards, repeat oiling every 3 to 4 weeks, or whenever the surface starts to look dry and pale instead of rich and slightly glossy.

How often should you deep clean with baking soda?

For most home cooks, deep cleaning a wooden cutting board with baking soda once every 4 weeks is enough. You might want to do it more often if:

• You cut raw meat on the board 3 or more times a week
• You notice strong smells after washing, especially garlic or fish
• You see visible stains that normal washing will not shift

For everyday care between deep cleans:

• Wash with warm water and a little washing up liquid straight after use
• Rinse and dry with a towel within 2 minutes
• Stand the board to dry fully before storing flat

Can you use this method on bamboo and acacia boards?

Yes, the baking soda method works well on both bamboo and acacia, as long as you rinse and dry thoroughly.

• Bamboo boards such as the Deer & Oak Large Bamboo Board (45x35cm, 1.8kg, Moso bamboo) respond well to light scrubbing and regular oiling. Bamboo is naturally dense and resists deep cuts.
• Carbonised bamboo like our Carbonised Bamboo Board (45x35cm, 1.9kg) has a darker finish, so avoid very harsh scrubbing in one spot to keep the colour even.
• Acacia boards such as the Large Acacia Board (45x35cm, 2.1kg) are slightly heavier and more oil rich, which helps them resist moisture when cared for properly.

If you want a ready to use set for this routine, the Deer & Oak Bamboo Double Pack pairs a 45x35cm board with a 38x28cm board so you can keep one mainly for meat and one for bread or vegetables.

Product to problem guide

Here is how to match your cleaning routine to the right Deer & Oak board:

• Problem: lingering meat and onion smells
  Use the baking soda and vinegar paste on a dedicated meat board. Our Large Bamboo Board (45x35cm) or Large Acacia Board (45x35cm) give enough space to keep juices contained. The Bamboo Double Pack lets you keep one board strictly for meat.
• Problem: heavy daily chopping for a family of 4
  Choose a heavier board like the 2.1kg Large Acacia Board and deep clean with baking soda monthly. Its weight helps it stay put while you scrub.
• Problem: limited space but you still want a hygienic board
  The Medium Bamboo Board at 38x28cm is easier to handle in smaller sinks during the baking soda routine and still large enough for most veg prep.
• Problem: visible stains on a serving board
  Our Carbonised Bamboo Board benefits from a gentler baking soda scrub and prompt oiling, which helps keep its darker colour smart enough for serving cheese or charcuterie.

Who this is for

Ideal for:

• Home cooks who want a clear, repeatable method to deep clean wooden or bamboo boards with baking soda
