Things You Will Need
Soft cloth, mild detergent, food grade mineral oil
The first step is to clean the board. Use mild soap and water being careful not to saturate the wood as the glue that holds the sections together can dissolve causing the sections to separate. Some of the newer cutting boards say that they are dishwasher safe, but I would rather clean them the old fashion way and be safe.
Pour a small amount of food grade mineral oil onto the surface of the cutting board. Using a soft cloth, rub the mineral oil into the wood. Wipe any excess mineral oil off and the cutting board is ready to use.
If the cutting board is new or is completely dry, it may be necessary to allow the mineral oil to soak into the wood before wiping off the excess.
Wood cutting boards once again becoming a popular choice among chefs and everyday cooks. Caring for oak wood cutting boards is easy with just a cloth and mineral oil.
Tips & Warnings
Oil a cutting board as often as needed to keep the wood from drying out.
Never use vegetable or olive oil to treat a wood cutting board as they can turn rancid making the cutting board smell and potentially be unsafe.
