How to Fix a Warped Cutting Board

Most people use their wooden cutting boards at least daily, if not more often. So, it is no surprise that people are devastated to find out such a vital kitchen tool has become warped. But don’t toss that warped piece of wood into the trash just yet, it may be possible to save it.

Keep in mind that the best way to fix a warped cutting board is to prevent it from happening to begin with. Wood Cutting Boards, an online retailer of high quality, engraved wood cutting boards recommends the following:

  • Hand wash only
  • Never submerge in water
  • Disinfect with vinegar
  • Remove stains with baking soda
  • Treat the board with the appropriate oils frequently

If your wooden cutting board does warp, here are a few home remedies that may fix it.

Heat and Moisture

This method works best for thinner boards, those 1” or less in thickness. Before attempting this method, be aware that there is a risk of your wooden cutting board cracking.

Place your warped cutting board on a flat surface with the warped side upwards.

Put a wet towel over the board and start to iron the cutting board just like an item of clothing, using as much steam as possible.

Use pressure on the board as this method combines pressure, heat and moisture to force the wood back into a flat position.


Fill a tall pot 1/3 of the way with water and place on the stove.

Place a colander in the pot and the board on top of that with the warped side facing down.

Simmer the water until steam forms. The heat and moisture will help the wood fibers flatten out again. Try to steam the entire board to prevent swelling from taking place.

Once flat, place heavy objects on top of the board while drying out to ensure it stays flat.

Keep in mind that this method has the highest risk of cracking the wooden cutting board.

Water and Pressure

Place your wooden cutting board in a large bucket of hot water and let it soak through (it will take between a few hours and overnight depending on the thickness of the board).

Then place the cutting board on a flat surface and place a flat object on top of it. After that, continue placing heavy objects on top, such as a stack of books. The heavier the objects, the better.

Keep it like this until the board dries back out completely, up to 3 days. The goal is to “warp” the wood back into a flat position.


Sanding a wooden cutting board should be used as a last resort only as it will alter the shape and look of the cutting board. For best results, a local woodworker can assist with this.
