Wood cutting boards are attractive and help keep knives sharp, but they are prone to drying. Dryness can cause the wood to warp and crack, resulting in permanent damage. To keep wood cutting boards in good shape, oil them regularly using the following steps.
Wash the cutting board and let it dry completely before applying any oil.
Work a food-grade oil, such as food-grade mineral oil, almond oil or walnut oil, into the wood using a paper towel or soft cloth. Avoid using cooking oils such as vegetable oil or olive oil to oil cutting boards, as these can go rancid. To make a natural cutting board conditioner, blend a mixture of oil and beeswax and work it into the wood. Work in the oil or conditioner along the natural grain of the wood.
Set the board aside for several hours to let the oil soak into the wood.
Use a paper towel or clean cloth to wipe away excess oil from the board. It should not feel sticky or oily to the touch.
