Cutting boards are a breeding ground for bacteria, so regularly sanitizing them is a good idea. There are a few techniques you can try, but I find this way to be the quickest, cheapest and most fuss-free:
-Lightly coat your board with food-grade mineral oil to protect against dryness from constant washing, which can result in cracks and splits. The mineral oil also helps to seal out moisture. Do this about 1-3 times a month.
-You can also use lemons to get rid of odors. What I’ll do is take half of a used lemon (the juices have been squeezed out already, since I don’t like to waste a whole half lemon for such small jobs), add a few drops of water to the pulp to loosen up the juices and then give the board a good rub down.
-Never leave your board submerged in water. Excessive moisture weakens wood.
