If you love to cook with garlic and other strong herbs and spices, your butcher block my not smell very good after a while. To sanitize a wood cutting board or counter top, wash with a solution of 1 teaspoon of bleach in 1 quart of water. To eliminate odors, pour some coarse sea salt onto the surface and scrub it into the wood using the face of a cut lemon. Don't forget to be kind to your wood and put some oil on it. This will help it last longer. Coconut oil is good to use
