How to clean chopping board before oiling

If you want your wooden or bamboo board to absorb oil evenly, the most reliable way is to clean it with hot water at around 45–50°C, a small amount of mild washing up liquid, and a coarse salt scrub, then let it dry upright for at least 12 hours before you start oiling. That simple routine gives oil a clear path into the grain and can add 5–10 years to the life of a good board.

Why cleaning matters before oiling your chopping board

Oiling a dirty or damp board traps stains, smells and moisture inside the wood. That is when you see patchy dark spots, raised grain and even warping. Cleaning properly before oiling does three important things:

• Removes surface grease so the oil can soak in evenly
• Lifts food particles and bacteria from knife marks
• Lets the board dry to a safe moisture level so it will not swell or crack

Whether you own a 45x35cm acacia block or a lighter 38x28cm bamboo board, the preparation steps are the same. The difference is that denser woods like acacia can take a touch longer to dry fully, so that 12 hour guideline really matters.

Step by step: how to clean chopping board before oiling

1. Scrape and rinse within 5 minutes of use

As soon as you have finished chopping, scrape off any food with a bench scraper or blunt knife. Then:

• Rinse both sides under hot running water at about 45–50°C
• Do not soak the board or leave it sitting in the sink
• Never put wooden or bamboo boards in the dishwasher, even at 40°C cycles

This quick rinse stops juices from meat, onion or citrus working their way deep into the grain, which makes cleaning before oiling much easier later.

2. Wash with mild soap and a soft brush

Use a pea sized amount of mild washing up liquid on a non scratch sponge or soft bristle brush.

• Scrub in the direction of the grain for 30–60 seconds per side
• Pay attention to knife marks and the area where you usually cut meat or fish
• Rinse thoroughly until the water runs clear and you see no soap bubbles

For dense boards like the Large Acacia Board DNO-ACB-LG at 45x35cm and 2.1kg, a brush with slightly firmer bristles helps reach into the tighter grain.

3. Disinfect naturally with salt and lemon (or vinegar)

Before oiling, you want to remove odours and surface bacteria without harsh chemicals. A simple method works well on both bamboo and hardwood:

• Sprinkle 1–2 tablespoons of coarse salt (about 15–30g) over the board
• Cut a lemon in half and use the cut side to scrub the salt into the surface for 1–2 minutes
• Alternatively, spray a 50:50 mix of white vinegar and water and leave for 5 minutes
• Rinse again with hot water at 45–50°C

The salt acts as a gentle abrasive that will not gouge the surface, while lemon or vinegar helps cut lingering smells from garlic, onion or raw meat.

4. Dry the board thoroughly before oiling

Drying is the step that most people rush, yet it has the biggest effect on how evenly your board accepts oil.

• Pat the board dry with a clean cotton or microfibre cloth
• Stand it upright on its edge or place on a rack so air can reach both sides
• Leave it to dry for at least 12 hours at normal room temperature (18–22°C)

For thicker or heavier boards like the 2.1kg acacia or 1.9kg carbonised bamboo, 16 hours is even better. If the board still feels cool and slightly damp to the touch, give it more time. Oil and moisture do not mix well inside wood fibres.

5. Check the surface is ready for oil

Before you open the bottle of mineral or board care oil, do a quick check:

• Run your palm across the surface. It should feel dry, not clammy
• Look against the light for any shiny wet patches or soap residue
• Smell the board. You should notice only a faint woody or lemon scent

If everything looks and feels clean, you are ready to oil. If not, repeat the wash and dry cycle rather than sealing in problems.

Cleaning tips for different Deer & Oak chopping boards

Different woods behave slightly differently when you clean and oil them. Here is how to get the best from three popular Deer & Oak options.

Bamboo boards: light, quick drying and low maintenance

The Large Bamboo Board DNO-BCB-LG at 45x35cm and 1.8kg and the Medium Bamboo Board DNO-BCB-MD at 38x28cm and 1.2kg both use Moso bamboo. It is naturally less absorbent than many woods, which means:

• They usually dry within 12 hours after a proper wash
• They benefit from oiling every 3–4 weeks in a busy kitchen
• A teaspoon of coarse salt is often enough for a full surface scrub

If you want a simple two board setup, the Bamboo Double Pack DNO-BCB-2PK combines both sizes at a total weight of 3.0kg and works well if you like to keep one board for meat and one for vegetables.

Carbonised bamboo: darker colour, same cleaning routine

Carbonised bamboo, like the Carbonised Bamboo Board DNO-CBB-LG at 45x35cm and 1.9kg, is gently heat treated for a deeper colour. The cleaning steps are identical, but there are two small differences when preparing to oil:

• Use slightly less salt and scrub gently to avoid visible light patches
• Dry for the full 12–16 hours so oil does not sit on the darker surface

If you like the look of a darker board for serving as well as chopping, you can see the carbonised finish on our carbonised bamboo board in the UK store.

Acacia boards: dense grain that loves regular oil

Acacia is a hardwood with a rich, varied grain. Our Large Acacia Board DNO-ACB-LG at 45x35cm and 2.1kg and the Medium Acacia Board DNO-ACB-MD at 38x28cm and 1.5kg are both FSC certified and arrive pre oiled.

When cleaning before oiling:

• Use a soft brush so you do not scratch the natural pattern
• Allow closer to 16 hours drying if your kitchen is cool or humid
• Expect to oil every 2–3 weeks if you use the board daily

If you prefer a matching set, you can find our acacia range in the acacia chopping board collection.

How often should you clean and oil your board?

Everyday washing is separate from the deeper clean you do before oiling. Here is a simple guide:

• After every use: scrape, rinse, wash with mild soap, quick dry
• Every 7–10 days: salt and lemon scrub if you cook often
• Every 3–4 weeks: deep clean and oil for bamboo
• Every 2–3 weeks: deep clean and oil for acacia or thicker blocks

If water stops beading on the surface and immediately soaks in, that is a clear sign the board is ready for a fresh coat of oil.
