How to: Clean and Disinfect a Butcher Block

End Grain boards are constructed by binding the wood sections vertically so that the “end” of the cut pieces become the cutting surface. This results in a board that is superior in its ability to resist and hide knife cuts with the added bonus of being more visually interesting. Because the grain is on-end, it allows knives to penetrate somewhat, making it a more forgiving surface that is easier on your cutlery, keeping your knives sharp longer. Below are some tips on how to clean and disinfect your cutting board.

Sanitize With Vinegar

Using water and dishwashing detergent can weaken surface wood fibers on cutting boards and butcher block countertops. To disinfect and clean your wooden surfaces, wipe them instead with full-strength white vinegar after each use. The acetic acid in the vinegar is a good disinfectant, effective against harmful bugs like E. coli, Salmonella, and Staphylococcus. When your wooden cutting surface needs deodorizing as well as disinfecting, spread some baking soda over it and then spray on undiluted white vinegar. Let it foam and bubble for five to ten minutes, then rinse with a cloth dipped in clean cold water.

Hydrogen Peroxide Will Kill Bacteria

Hydrogen peroxide is a surefire bacteria-killer—just the ally you need to fight the proliferation of bacteria on your cutting board. Especially useful after you cut chicken or other meat, Hydrogen Peroxide in low concentrations is safe to use on food surfaces. To kill the germs on your cutting board, use a damp cloth to remove any visible grime with white vinegar, rinse, then use another to wipe it with hydrogen peroxide (3%) and allow to sit for 10 minutes before drying.
(Be sure not to mix the vinegar and hydrogen peroxide)

Lemons Will Remove Odor

If your cutting board smells after you chop onions, crush garlic, cut raw or cooked meat and chicken, or prepare fish, get rid of the odor by rubbing the cut side of a lemon after regular cleaning.

Salt Will Help Deep Clean

If you clean cutting boards and breadboards with soap and water, rub them afterwards with a damp cloth dipped in salt. The boards will be lighter and brighter in color.
