Butcher block...

Well, we have wooden cutting boards as well as a corian board. I have always used the same thing in this link. My grandfather was a beekeeper and he made the mixture to keep my grandmothers woodenboards proper.
Believe it or not , a piece of "Corian" is one of the best materials to use for a cutting board. It does not harbor bacteria in a sense. If you wash it down after use with any good cleansing soap ( i.e. dawn or something similar), it will last a very long time. I know it does not have the old school look and contrast to the kitchen for everyone, but I do have one of these too. Have used it for 15 years.
I hope this helps out some. Merry Christmas to everyone.
