Grab the kitchen sponge and dish soap! It is necessary to clean your cutting board immediately after using to prevent stains from setting in and to remove bacteria.
Dry it IMMEDIATELY! Stand the cutting board up on it's side to allow maximum air circulation around the entire surface. This helps prevent the water from getting trapped underneath and warping your board.
In order to remove stains from your board (like strawberries!), cut a lemon in half and sprinkle about 2 TB of baking soda on the surface. Gently rub the baking soda into the board, occasionally squeezing additional lemon juice. Rinse with water and remove any water with a paper towel. Set it up on its side to allow it to dry thoroughly.
Butchers have been doing it for centuries! Rub Kosher salt and lemon juice into your board and it will remove those pesky garlic and onion smells. Rinse it with water to remove the salt and remove any excess water with a paper towel. Let it air dry on it's side.
You can combine the KOSHER SALT and BAKING SODA and remove stains and smells all at once!
Repeated use results in a dry cutting board that can lead to cracks. I suggest at least once a month, rubbing some mineral oil into the surface. I use this one pictured above from Ikea.
Take care of your cutting boards and they will help you prepare healthy food and last for many years!
