kpinky, please don't put anything wooden in the dishwasher....
unless it is a piece that you don't care much about. Wood is like a sponge and absorbs the water. You should never let your wood kitchen ware sit in a sink full of water either, just quickly wash wood items (wooden utensils, cutting boards, serving bowls,wood handled knives, etc) with a little warm soapy water.
I work in a small store that sells all American made crafts. We sell MANY wood utensils and cutting boards. Every piece that leaves our stores is acompanied with a carecard that says to never put these items in the dishwasher. I have seen the results when they are returned to us. The wood splits, it is all swollen and out of shape from absorbing water, the beautiful grain has disappeared and the colors (from different types of woods) are all dissolved.
Your wood pieces will last a lifetime with a little care. Once or twice a year, lightly sand them down to reveal the natural grain and bring out the colors again. Then lightly oil with mineral oil, beeswax or other food safe oil product. Your pieces will look brand new!
