Refinish Cutting Board with 100, 240, and 3000 Grit Sandpaper for a Food-Safe Finish

Over time, cutting boards can become rough, stained, and harbor knife marks. By using a sanding sequence of 100, 240, and 3000 grit sandpaper, you can restore a smooth, food-safe surface that's ready for oiling.

Why This Method Works

100 grit removes deep cuts and stains. 240 grit smooths the surface for a consistent appearance. 3000 grit polishes the wood for a silky touch that resists moisture penetration once oiled.

Tools & Materials

• Wet/dry sandpaper: 100 grit (100-pack), 240 grit (25-pack), 3000 grit (100-pack)
• Flat sanding block
• Food-grade mineral oil or beeswax finish
• Microfiber cloths
• Vacuum or brush

Recommended Grit Sequence

• 100 grit: Remove knife marks and stains. (100-pack)
• 240 grit: Smooth surface for even oil absorption. (25-pack)
• 3000 grit: Burnish for a silky, moisture-resistant finish. (100-pack)

Step-by-Step Process

1. Prep. Clean the cutting board and allow it to dry completely before sanding.
2. Initial sanding. Use 100 grit sandpaper to remove deep knife marks, working evenly across the surface.
3. Intermediate smoothing. Switch to 240 grit sandpaper to refine the surface and prepare for finishing.
4. Final polish sanding. Lightly sand with 3000 grit sandpaper to create a silky feel.
5. Oil application. Apply food-grade mineral oil or beeswax, let it soak in, then buff with a clean cloth.

Special Considerations

Always use food-safe finishes on cutting boards to ensure safety during food preparation.

Pro Tips

• Sand both sides of the board to prevent warping.
• Re-oil monthly for optimal protection.
• Wipe away excess oil to avoid sticky residue.

Aftercare

• Hand wash only—never soak or put in the dishwasher.
• Reapply oil as needed to maintain the finish.

FAQs

• Can I start with 240 grit? Only if there are no deep cuts or stains.
• Will 3000 grit make it too slippery? No—it creates a smooth feel without affecting cutting safety.
• Is beeswax better than mineral oil? Beeswax offers more water resistance, while mineral oil is easier to apply.
