Making Mineral Oil Wax
After having numerous people asking me if I had any food grade wax polishes, I decided I should add some to my shop. Now, while you could use wax polish made with raw linseed oil (not boiled), or tung oil on cutting boards, they do both have a distinctive smell that could possibly impart a slight scent to your food. Also, they both are curing oils, which means they dry and a film is created which creates a finish, however slight.
While it is ideal to use a curing oil for wood finishing projects, it's not ideal for cutting boards and cooking utensils. For those objects, you really want to use a non-curing oil such as mineral oil.
For this batch of cutting board wax finishes, I used 100% food grade mineral oil from General Finishes, and 100% natural beeswax. The mineral oil imparts no color, and neither does the wax to the wood, so all the color of the polish comes from the beeswax. The polish has a very nice honey-like color and has a great consistency, making it easy to work with.
While this polish is great to use on any kitchen tools, it's also ideal to use on metal in the shop where you don't want a film to build, such as on your hand saw blades, cast iron, table saw tops etc.. Applying a coat of non-curing beeswax polish every few weeks on these objects will protect them and keep them in great shape.
