If you want your wooden cutting board to last 5 to 10 years, the simplest upgrade to your routine is this: clean it with coarse salt and water once a week. Salt gently scrubs the surface, draws out moisture and odours, and helps keep boards like our 45x35cm Large Bamboo Board (1.8kg) and 45x35cm Large Acacia Board (2.1kg) in good condition without harsh chemicals.
Why clean a wooden cutting board with salt instead of harsh detergents?
Wooden and bamboo boards are naturally porous. Heavy use of strong detergents or soaking in water can cause warping, cracking and raised grain in as little as 12 to 18 months. Coarse salt, used correctly, gives you three advantages in one simple step:
- Mild abrasion that lifts dried food and stains without deep scratching
- Moisture draw that helps pull out liquid from the surface where bacteria like to grow
- Odour control so smells from onion, garlic and raw meat do not linger
When you pair salt cleaning with regular oiling, a quality board like the Deer & Oak Carbonised Bamboo Board can stay smooth and usable for many years of daily chopping.
How to clean your wooden cutting board with salt in 5 simple steps
This method works on bamboo and hardwood boards, including our 45x35cm and 38x28cm sizes. For everyday cooking, doing this once a week, or after heavy meat prep, is usually enough.
-
Rinse and wipe
Rinse the board under warm running water for 10 to 15 seconds and scrape off any stuck bits with a bench scraper or the flat side of a knife. -
Sprinkle coarse salt
Scatter 1 to 2 tablespoons of coarse sea salt or kosher salt evenly over the surface. Avoid fine table salt as it dissolves too quickly and has less scrubbing power. -
Scrub the surface
Use a damp cloth, a soft sponge or half a lemon to scrub in small circles for 60 to 90 seconds. Pay extra attention to knife marks and the centre of the board where you chop most. -
Rest briefly
Leave the salty surface for 5 minutes. This short rest lets the salt draw out extra moisture and odours from the top few millimetres of the wood. -
Rinse and dry upright
Rinse quickly with warm water, pat dry with a clean tea towel and stand the board upright on its edge so air can reach both sides. It should feel dry to the touch within 30 to 60 minutes in a normal kitchen.
For deeper conditioning, you can follow with a light coat of food safe mineral oil once the board is fully dry. Our customers often oil every 4 to 6 weeks, especially for larger boards like the 45x35cm sizes.
What problems does salt cleaning actually solve?
Salt is not magic, but it does solve several common board problems when used consistently.
1. Lingering food smells
Onions, garlic, fish and strong cheeses can leave odours that last for days. Salt helps by:
- Absorbing some of the surface moisture that carries odour molecules
- Working as a gentle abrasive to remove the top stained layer of wood fibres
On our Medium Bamboo Board (38x28cm, 1.2kg), a weekly salt scrub keeps one side fresh for fruit and bread while the other side handles stronger flavours.
2. Stains from beetroot, berries and herbs
Salt can reduce light staining by lifting pigment from the surface. For fresh stains, a 2 minute scrub with salt and a cut lemon, followed by a rinse, usually fades the mark by 50 to 80 percent. Deep, old stains may not disappear fully, but they often become much less noticeable.
3. Slight surface roughness
Over time, water and knife marks raise the grain of the wood. A monthly salt scrub, followed by oiling, helps keep the surface of boards like our Large Acacia Board (45x35cm, 2.1kg) smoother for longer, which is kinder to your knives and easier to wipe clean.
4. Over reliance on harsh cleaners
Bleach sprays and dishwasher tablets can shorten a board’s life from 8 to 10 years down to 1 to 2 years. Salt lets you reserve strong cleaners for rare deep cleans, so your board fibres are not stripped or dried out every week.
How often should you clean a wooden cutting board with salt?
Frequency depends on how you use your board and what you are preparing on it:
- Daily use for vegetables and bread: Salt clean every 7 to 10 days
- Regular meat and fish prep: Salt clean every 3 to 4 uses of raw protein
- Serving board use only: Salt clean once or twice a month
Between salt cleans, a quick wash with mild washing up liquid and warm water for 20 to 30 seconds is enough for most home cooking, as long as you dry the board upright straight away.
Deer & Oak wooden boards that respond well to salt cleaning
All Deer & Oak boards are pre oiled so they are ready to use from day one. Salt cleaning works especially well on our bamboo and acacia ranges, as both materials are dense enough to handle gentle abrasion without wearing out quickly.

Not recommended for...

FAQs
Q: Does cleaning a wooden cutting board with salt kill bacteria?
A: Salt on its own is not a registered disinfectant, but it does help by drawing moisture away from the surface and making it harder for bacteria to thrive. For home use, a routine of hot water, mild washing up liquid, salt scrubbing and thorough drying upright provides a sensible level of hygiene for most wooden boards.
Q: Can I use table salt instead of coarse salt on my cutting board?
A: You can, but coarse salt works better. Fine table salt dissolves very quickly, so you lose much of the gentle scrubbing effect that helps lift stains and food particles. A 1 to 2 tablespoon sprinkle of coarse sea salt or kosher salt gives you more control and a more even clean across a 38x28cm or 45x35cm board.
Q: Will salt damage my bamboo or acacia cutting board over time?
A: Used once a week or less, salt is unlikely to damage a quality bamboo or acacia board. The key is to scrub with light to moderate pressure for no more than 2 minutes, rinse promptly and dry upright. Boards like our 1.8kg Large Bamboo and 2.1kg Large Acacia are dense enough to handle this routine for many years.
Q: Should I still oil my board if I clean it with salt?
A: Yes, oiling is still important because salt cleaning only affects the surface. A thin coat of food safe mineral oil every 4 to 6 weeks helps prevent cracking and warping and keeps the board less absorbent. Many Deer & Oak customers salt clean weekly and oil every second or third weekend for a balanced routine.
