How to Oil a Wooden Cutting Board

Why Oiling a Wooden Cutting Board Matters

Wood is a natural material that dries out over time, especially with regular washing. An un-oiled cutting board becomes dry, rough, and prone to cracking and warping. It also becomes more porous, absorbing food juices and bacteria more deeply. Regular oiling seals the wood, extends its life dramatically, and keeps the surface smooth and easy to clean.

What You'll Need

• Howard food grade mineral oil
• CLARK'S mineral oil and carnauba wax set (for deeper conditioning)
• Clean cloth or paper towels
• A dry, clean cutting board

Which Oil to Use

Only use food-safe oils on cutting boards:

• Food grade mineral oil: The gold standard — odorless, tasteless, doesn't go rancid, deeply penetrates wood
• Beeswax / carnauba wax conditioner: Applied after mineral oil for a protective surface seal
• Avoid: Olive oil, vegetable oil, coconut oil — all go rancid inside the wood over time, causing unpleasant odors

Step-by-Step: How to Oil a Wooden Cutting Board

1. Make sure the board is completely clean and dry — never oil a damp board
2. Apply a generous amount of food grade mineral oil to the surface
3. Spread evenly with a clean cloth, rubbing in the direction of the grain
4. Apply to all surfaces: top, bottom, sides, and any handles
5. Let the oil absorb for at least 4–6 hours, or overnight for best results
6. Wipe off any excess oil that hasn't absorbed
7. For deeper conditioning, apply a second coat after the first has absorbed

Finishing with Wax (Optional but Recommended)

After oiling, apply the carnauba wax conditioner from the CLARK'S set:

1. Apply a thin layer of wax to the oiled, dry surface
2. Rub in with a clean cloth in circular motions
3. Let sit 10–15 minutes
4. Buff with a clean cloth to a smooth finish

The wax creates a protective barrier on top of the oil, repelling water and food more effectively than oil alone.

How Often to Oil

• New board: Oil 3–5 times before first use, letting each coat absorb fully
• Regular maintenance: Once a month for boards used daily
• Quick test: Sprinkle a few drops of water on the board — if they soak in instead of beading up, it's time to oil

Final Thoughts

Oiling a wooden cutting board takes 10 minutes of active work plus absorption time. Food grade mineral oil is the best choice, and finishing with carnauba wax adds extra protection. Make it a monthly habit and your board will stay beautiful and functional for decades.
