These boards, blocks, and trays are made to last a lifetime, but they do require some care to preserve and maintain them. 


Never place your board, tray, or block in the dishwasher. Feel free to clean with hot soapy water, but be sure to towel/air dry after.  


Depending on use, I recommend food grade mineral oil or beeswax conditioner be reapplied to the boards, trays, and blocks every month. This will prevent drying and cracking, and will also help repair knife marks by keeping the mineral oil in and moisture out.  Below is a link to an oil/wax that I recommend, but you can find these items at most home improvement stores.


For longevity of your piece, store in a flat position. While not necessary, storing items in a flat position on a solid surface helps prevent warping.
