Please never put it in the dishwasher. This will encourage cracks and warping.
Do not soak the board. Remove food debris, hand wash with warm soapy
water and rinse off. Make sure all faces of the board are washed.
Equal water distribution helps alleviate warping.
Stand your board on one of its long sides so that the top and bottom face dry
equally.
Once a month when the board is completely dry, apply a generous coating of food
safe mineral oil to all sides with a lint free cloth. Allow the oil to soak in for
two hours. Buff off any excess oil.
