How Do You Seal A Bamboo Cutting Board?
To seal a bamboo cutting board, first wash and dry it thoroughly. Then, using a soft cloth or brush, apply a thin, even layer of food-grade mineral oil or a mixture of beeswax and mineral oil to the entire surface of the cutting board. Let it sit for several hours or overnight to allow the oil to penetrate the bamboo. Wipe off any excess oil or wax with a clean cloth. Repeat the process once a month or as needed to maintain the seal.
