Fruits and vegetables are great for being cut on a wood cutting board because, even raw, they do not carry bacteria such as e. coli. Many people also prefer wood cutting boards because they are easier on the blade of a knife when compared to the hard, rigid surface of a plastic board. Wood cutting boards must never be run through a dishwasher because it will quickly warp the wood with its high temperatures and loads of water. To wash a wood cutting board, it is best done with a sponge and liquid soap.
