If you have a cutting board that you made or purchased from the store, excessive exposure to water can be bad. Water can be sucked into the wood and damage the wood board, eventually leading to a crack. Instead of throwing it out, you may want to let it sit for a couple of weeks so that the water is able to dry out.
In this tutorial, you'll find out what you can do once you're board is free of any liquid. It's an easy fix that will ensure that you won't have to waste any money and have a fully functioning cutting board. Good luck and enjoy!
