Over time you might notice stains, excessive cut marks, and that the wood appears to be drying out. Fortunately, it’s quite easy to refurbish your favorite block and bring back its original finish!
Sandpaper: coarse (80-grit), medium (120-grit), and fine (220-grit)
Wood Butter: Place 1 part beeswax into a large glass canning jar, and then let the jar sit in a pan of simmering water. Once beeswax has melted, add 4 parts coconut oil to the jar, and stir until completely melted and combined with beeswax. Remove from heat, and allow to cool and solidify.
Clean + Disinfect
Use a cloth to wipe the cutting board with vinegar. Depending on the state of your board, you may need to soak the board in vinegar for a few minutes to be sure to really disinfect it. Rinse with warm water, and wipe dry. Sprinkle coarse sea salt onto the board, and scrub the salt into the board with a lemon half, being sure to squeeze juice out as you scrub. Let the lemon juice and salt mixture sit for a few minutes before rinsing with warm water. Wipe dry with a cloth.
Starting with 80-grit sandpaper, sand the cutting board along the grain to remove deep cuts and dents. Wipe with a damp cloth, and let dry completely before repeating with 120-grit and finally 220-grit sandpaper. The cutting board should feel quite smooth at this point and will be much lighter in color.
Use a clean cloth to rub wood butter into the board until well oiled, being sure not to skip the edges and back. Let sit for a few hours, and then buff with a clean cloth to remove any remaining surface oil so the board is no longer tacky.
