Season your wooden cutting board to make it last longer. A seasoned cutting board is a healthy cutting board. Seasoning a wooden cutting board helps to keep it from being stained, absorbing food particles and building up bacteria in the wood fibers. The process takes very little time after the initial seasoning, takes very little money, and is worth the effort, as it greatly extends the life of your cutting board. You should season your brand new wooden cutting board before you use it for the first time.
Pour some mineral oil onto a soft rag. Rub the oil into the surface of the wood. Cover the entire surface of the cutting board, even if you do not plan on cutting food on the back of the cutting board.
Keep rubbing in the oil until the wood stops absorbing the oil.
Wipe off any excess oil with a clean rag and allow the oils to sink into the wood.
Wash your properly seasoned wooden cutting board with hot water and soap without fully immersing the cutting board into the water. Use plain white vinegar to remove any stains. Use salt as an abrasive to remove stubborn stains.
Dry the cutting board with a soft cloth, or leave it to air dry.
Re-apply the mineral oil on a regular basis, such as once a month, depending on how often you use your cutting board, to keep it in good shape.
