How do I rid my cutting board of onion and garlic odors?

Lemon or lime juice with a little salt will go a long way to reducing odor. Sprinkle your Boos cutting boad with kosher or table salt. Cut a lemon or lime into quarters and use these quarters to rub the salt into the board, squeezing juice onto the board as you go. Let sit for 2-3 minutes and then wipe the cutting board clean with a damp cloth. Use a clean paper towel to remove excess water or let the board air dry by standing it on end.
