Any time the wood begins to look dry, take butcher block butter or oil and rub it into the wood, top, bottom, and sides. Let it sit for 30 minutes then wipe clean with a clean cloth. In a dry climate, you may have to do this once a week. In a humid climate, maybe once a month. If you put oily meat on the board, it is recommended you rub some butcher block butter on the board to seal all the pores in the wood.
Hand wash only with cool water and a mild soap. Rinse thoroughly. Soap removes oil, and these boards are sealed with oil and beeswax. Add butcher block butter when it dries.
DO NOT CUT WITH A SHARP KNIFE ON EPOXY! Not only will the knife cut into the epoxy producing fine epoxy particulates, but it will scratch the epoxy and dull your knife. Epoxy is very strong.
Do not leave your epoxy board in direct sunlight, it will yellow over time and could warp. If it warps, lay it against the warp on a flat surface in the sun for a few hours. The heat will soften the epoxy and it will flatten out.
