4. How to care for them: Wooden cutting boards should be washed in warm water and dried immediately after use, then placed on a horizontal surface to prevent them from warping. To remove stubborn stains from strawberries and the like, sprinkle the entire board with salt or baking soda, then rub it with a halved lemon. It's also a good idea to oil your boards once a year (though some people treat their boards as often as once a month). To oil your boards, use food-grade oil like beeswax or mineral oil, which can usually be found in pharmacies. Don't use olive or vegetable oil, though, as they can turn rancid and produce a off-putting smell. Apply the oil to your dry board and let it sit for a few hours, then wipe off the excess.
