After use, clean the olive wood cutting board briefly with lukewarm water and a mild dish soap. Dry it thoroughly immediately afterward, as prolonged contact with moisture can cause the wood to swell or crack. To keep the surface supple and prevent cracking, you should regularly (about once a month) rub the board with a food-safe oil, such as linseed oil or a special care oil. Under no circumstances should the board be placed in the dishwasher, as the heat and high water pressure will make the material brittle and prone to cracking.
