Mineral oil is the best oil for cutting boards in the kitchen, we do not recommend natural oils such as vegetable, corn, olive, peanut or walnut oil, as these are rich in fats that will eventually oxidize and go rancid, creating a foul smelling board. Also, never use standard mineral oil from a hardware store that is not rated as food safe, as that is meant for machine lubrication and not for contact with food. It is not worth jeopardizing your health for a few dollars! FOOD SAFE MINERAL OIL FOR WOOD CUTTING BOARD: Be safe with our 100% natural mineral oil. It's a perfect fit for all of your wood cutting boards, utensils, countertops, salad bowls and wooden products since it's odorless and colorless! RESTORE, PROTECTS AND EXTENDS THE LIFE OF WOODEN PRODUCTS: Mineral oil works on everything all the time! By hydrating your board with our food grade penetrating oil, you seal the wood which will protect it against water, prevent cracking, warping and drying. PREVENT STAINS: Seasoning your cutting boards with our mineral oil will protect it against stains! Since wood is porous without a finish the wood cutting boards or utensils often absorb food juices, colors and aromas and we don't want that. EASY TO APPLY AND USE: The disc top cap is mess free and makes it easy to apply wood oil. For brand new boards, apply once every one or two weeks for the first 3 months. After that once a month should do the trick. Be generous with the application, especially if the wood is dry! INDUCTION SEAL: WoodForChef uses an induction seal instead of regular pressure seal. That way we ensure that our products arrive at your house intact! No leak, no halfway full bottle!
