How should I properly maintain a bamboo cutting board by oiling it?

To properly maintain a bamboo cutting board by oiling it, you should use food-grade mineral oil or bamboo oil. Apply a thin layer of oil to the board, let it sit for a few hours or overnight, then wipe off any excess oil. Repeat this process every few weeks or as needed to keep the board well-conditioned and prevent it from drying out or cracking.
