Clean a wooden cutting board with soap and a little water. Follow this by wiping it with a damp cloth dipped in salt. The salt will give the wood a new look and a fresh feeling. Similarly, you should wipe your wooden cutting board, breadbox, or salad bowls now and then with a sponge dipped in vinegar; it removes any grime and odor buildup, since wood tends to harbor grease and odors. A baking soda solution can also be used for this purpose. Another great cutting board cleaner is lemon juice. Just rub some into the cutting board and leave it overnight. In the morning, rinse thoroughly.
When your wooden utensils or cutting boards start to fade, crack, or become brittle, don't throw them out. Instead, apply a generous amount of olive oil onto them and rub it into the wood, following its grain. Depending upon how dry and cracked they are, it may take two or three applications to return them to a healthier state. If any oil seems to "pool," or if the utensils or cutting boards are still very oily to the touch even after letting them sit for a while, gently dab up the excess with an absorbent, lint-free cloth.
