  • After washing, dry up the board immediately. Prolonged exposure to moisture can result in cracks. 
  • For disinfection, use diluted vinegar or baking soda mixed in water. 
  • A commercial sanitizer like the Quaternary Ammonium sanitizer is ideal for porous surfaces. They are non-corrosive and do not cause crevices.
