Wood chopping blocks and cutting boards are exposed to a variety of stain-causing foods. When you use your chopping block to cut or slice greasy foods, the grease absorbs into the wood. Leaving grease stains could cause harmful bacteria to develop and transfer to other foods prepared on the chopping block. For the safety of your food and family, remove the grease stains with a simple solution of bleach and water.
Cover the grease stain on your wood chopping block with baking soda. Allow the baking soda to remain on the surface for 20 minutes to absorb the grease. Brush the baking soda off the wood into the garbage.
Mix 1 tsp. bleach with 1 quart warm water in a bucket. Dip a nylon dish scrubber in the diluted bleach solution and scrub the surface of your chopping block to break down and remove grease. Rinse your wood chopping block well.
Place a few drops of dish-washing detergent on your nylon dish scrubber. Wash the wood surface with the dish soap to remove any last traces of oil stain.
Rinse your chopping block with warm water. Dry with a clean kitchen towel, and allow the chopping block to air-dry completely.
