I pre-oil the boards before shipping with a cutting board oil from Amazon. I believe linseed oil and beeswax are good preservatives. Mineral oil okay as long as it it food grade.
No matter what would is used, they should be oiled regularly to prevent drying out and splitting. Stu Cutting boards available at: http://www.cncphotoalbum.com/cutting_boards cnc-list@cnc-list.com ---- cnc-list
