Wash wooden cutting board with soap or liquid detergent, hot water and a sponge after each use. Hand dry cutting board with a towel or place on the edge of your dish drain to allow to dry. Don't leave a wooden cutting board soaking in a dish pan or sink. Never put a wooden cutting board in a dishwasher.
If your wooden cutting board begins to look dry or dull apply wood care oil. Allow a few minutes for the oil to set in and then wipe off all traces of wood care oil. This process should be done at least 2-3 times each year.
