If you want to know how to remove scratches from a bamboo chopping board, the most effective method is to sand the surface with 120–240 grit sandpaper, then re oil it with food safe mineral oil. For light marks this takes about 15–20 minutes on a standard 45x35cm moso bamboo board, and can extend the life of your board by 5–10 years if repeated regularly.
Why bamboo chopping boards scratch and when to fix them
Bamboo is naturally harder than many timbers used in the kitchen, yet even eco friendly moso bamboo chopping boards will pick up knife marks over time. Shallow scratches are mostly cosmetic. Deeper grooves, especially on a meat or fish cutting board, can trap moisture and bacteria and are worth fixing as soon as you notice them.
If your board is less than 2cm thick and has deep cuts on both sides, you can usually sand and restore it at least 3–4 times before the thickness becomes an issue. On a Deer & Oak Large Bamboo Board (45x35cm, 1.8kg) that can mean 8–12 years of steady use with good care.
Step by step: how to remove scratches from bamboo chopping board
Here is a simple method that works on moso bamboo, carbonised bamboo and other bamboo kitchen boards.
1. Clean and dry the board properly
- Wash the bamboo chopping board in warm water with a small amount of washing up liquid.
- Scrub gently along the grain with a soft brush or cloth to remove food particles from the scratches.
- Rinse and dry with a clean towel.
- Let it air dry upright for at least 2–3 hours, or overnight if the board felt very damp.
Never soak a bamboo cutting board in water and never put it in the dishwasher. Prolonged soaking causes swelling which makes scratches and warping worse.
2. Light sanding for shallow scratches
For light knife marks and surface scuffs on your kitchen board:
- Use 180 or 220 grit sandpaper for a gentle refresh.
- Sand by hand along the grain, not across it, using even pressure.
- Work over the whole surface so you do not create low spots.
- Wipe away dust with a slightly damp cloth and let dry.
This is usually enough for boards that are only 6–12 months old and used with standard kitchen knives.
3. Deeper sanding for heavy scratches and grooves
If you can feel the scratch with a fingernail or see visible grooves:
- Start with 120 grit sandpaper to remove the worst of the cuts.
- Sand the whole face of the bamboo cutting board, not just the damaged area.
- Once the deepest marks are reduced, move up to 180 grit, then 220 grit for a smoother finish.
- Always sand in the same direction as the grain pattern of the moso bamboo strips.
A 45x35cm board like the Deer & Oak Large Bamboo Board usually takes about 10 minutes of steady sanding for heavy wear on one side. A 38x28cm Medium Bamboo Board will often take around 6–8 minutes.
4. Clean off the dust
- Wipe the board with a dry cloth to remove most of the sanding dust.
- Follow with a slightly damp cloth to pick up the fine particles.
- Let the board dry completely for 30–60 minutes before oiling.
Do not use any household cleaners or sprays at this stage. You want the pores of the bamboo open so they can absorb oil evenly.
5. Re oil the bamboo chopping board
Oiling is what brings a sanded bamboo board back to life and helps hide remaining hairline scratches.
- Use a food safe mineral oil or a dedicated board conditioner. Avoid olive oil or other cooking oils that can turn sticky.
- Pour about 1–2 teaspoons of oil onto the surface of a 45x35cm board.
- Spread with a lint free cloth in thin, even layers along the grain.
- Let the board absorb the oil for at least 20–30 minutes.
- Wipe off any excess with a clean, dry cloth so the surface is not greasy.
If the board looks patchy after the first coat, add a second light coat and wait another 20 minutes. New or very dry boards can need 2–3 coats the first time.
6. Repeat on the other side if needed
For a double sided chopping board, repeat the steps on the reverse. Many Deer & Oak customers use one side for bread and vegetables and the other for meat, so it is worth keeping both sides in good condition.
Preventing new scratches on your bamboo board
You cannot avoid every knife mark, but you can reduce deep scratches and keep your eco friendly moso bamboo board looking good for longer.
- Use the right knives Soft stainless steel kitchen knives are kinder to bamboo than very hard or serrated blades.
- Rotate usage Alternate sides of the board each day so wear is even.
- Oil regularly For boards used daily, oil every 4–6 weeks. For lighter use, every 2–3 months is usually enough.
- Avoid heavy cleaver work If you often use a cleaver or tenderiser, consider a thicker butcher block for that task and keep your bamboo board for slicing and chopping.
Choosing the right bamboo board to minimise scratches
Not all bamboo chopping boards are the same. The density of the bamboo, thickness of the board and quality of the finish all affect how quickly scratches appear and how easy they are to remove.
Deer & Oak uses tightly packed moso bamboo strips that are factory pre oiled. This gives a smoother surface from day one, which means fewer raised fibres and less aggressive scratching in the first year of use.

Who this is for and who it is not for
Ideal for:
- Home cooks who want to restore an eco friendly moso bamboo chopping board rather than replace it every 1–2 years.
- Families who use a main kitchen board daily and are happy to spend 20–30 minutes every few months on basic care.
- People who prefer natural materials and want a cutting board that can last 5–10 years with sanding and oiling.
- Anyone choosing a Deer & Oak board and wanting a clear care routine to keep scratches under control.
Not recommended for:
- Those who want a completely scratch free surface and are bothered by any knife marks at all.
- Busy commercial kitchens that use heavy cleavers and need boards that can go in a dishwasher.
- People who do not want to sand or oil and prefer a board that can simply be replaced when worn.
- Anyone using very hard specialist knives that may chip on bamboo and are better suited to softer end grain boards.
Common mistakes when trying to remove scratches from bamboo
- Using the wrong oil Olive, sunflower or rapeseed oil can go rancid and leave a smell. Always choose food safe mineral oil or a board conditioner.
- Sanding across the grain This can leave visible swirl marks that are harder to hide than the original scratches.
- Over sanding one spot Focusing only on a single scratch can create a dip. Always sand the whole face evenly.
- Skipping drying time Oiling a damp board traps moisture and can cause warping over time.
Deer & Oak product recommendations for easier scratch care
If you are choosing a new bamboo chopping board and want one that responds well to sanding and oiling, the Deer & Oak range has been designed with long term care in mind.
- For a main family board: The Large Bamboo Board 45x35cm (DNO-BCB-LG) gives plenty of space, weighs 1.8kg so it stays put on the worktop, and the moso bamboo construction sands back cleanly when scratches build up.
- For a two board system: The Bamboo Double Pack (DNO-BCB-2PK) pairs a 45x35cm and a 38x28cm board so you can keep one for meat and fish and one for vegetables, which reduces deep scoring in a single area.
- For a darker finish that hides light marks: The Carbonised Bamboo Board 45x35cm (DNO-CBB-LG) weighs 1.9kg and its rich colour makes fine scratches less visible between sanding sessions.

Q: How often should I sand my bamboo chopping board to remove scratches?
A: For most home kitchens, light sanding once or twice a year is enough, as long as you oil the board every 4–8 weeks. If you cook daily and see deep grooves forming sooner, you can sand just the working side every 4–6 months. Try not to sand more than 3–4 times per side over the life of the board so you keep a good thickness.
Q: Will removing scratches make my bamboo board less hygienic or damage it?
A: When done correctly, sanding and re oiling actually makes a bamboo kitchen board more hygienic, because you remove deep cuts where food and moisture can sit. Use fine to medium grit sandpaper, keep the surface flat, and finish with a food safe oil so the bamboo fibres are sealed again.
Q: Can I use the same method on carbonised bamboo and standard moso bamboo?
A: Yes, the process for how to remove scratches from bamboo chopping board surfaces is the same for both carbonised bamboo and natural moso bamboo. Just be a little gentler on carbonised boards, as over sanding can lighten the darker surface colour in patches if you remove too much material.
Q: What if my bamboo cutting board is warped as well as scratched?
A: Minor warping can sometimes be improved by sanding the high spots and then storing the board flat with a little weight on top for a few days. If the board is badly twisted or has deep cracks, it is safer to replace it and consider a thicker model, such as a butcher block, for heavy chopping jobs.
