Caring For Cutting Boards

DO's

Wash your cutting board after use in warm to hot soapy water then rinse thoroughly. Wipe dry immediately and let stand on its side or on a drying rack until it's fully dried. This allows for good airflow around the board.
Cutting boards need to be reconditioned with mineral oil and/or beeswax every few months depending on how often the board is used. For heavy daily use, re-oil the cutting board every month or as often as desired. This can be purchased online and/or at most hardware stores.
If your cutting board retains any odors, there are a number of natural remedies to help mitigate any smells. Cutting a lemon in half, and rubbing the juice over the board does wonders. This also works with salt, baking soda, and vinegar. Apply your choice and let sit for a good 20 minutes. After, wash in the sink with soap and warm water. Repeat if necessary.

DONT's

Put the board in the dishwasher. The heat and water will warp and splinter the wood.
Dunk or let the board stand in water. The wood will absorb water and potentially warp.
Use bleach. This will stain the wood and/or excessively dry out the wood.
Do not recondition with anything but mineral oil or bees wax. Vegetable oil, olive oil, and many other oils will turn rancid after a period of time and give off an odor.
Do not scrub cutting board with steel wool or anything too abrasive as this can remove the conditioning oil.
Lay the board flat to dry. If the board dries on one side, it will cause the wood to warp.
