Can you put a wooden cutting board in a dishwasher?

Question

I am afraid that handwashing will not kill bacteria as well as dishwashing. Does anyone have any suggestions on how to kill bacteria and avoid getting mold spots as well?

Answer 1

How to Clean Wooden Kitchen Items

Wash wooden bowls, spoons, and cutting boards in hot, soapy water, then rinse thoroughly with hot water and dry. Never let wood sit in water or it may crack or warp.
While a sponge is fine for washing bowls and utensils, use either a brand-new sponge or a soft-bristled brush for cutting boards, to avoid transferring bacteria from an older sponge to the cracks and crevices left on the board from cutting and chopping.

To get out tough stains, go over the board with a freshly cut lemon, which will bleach and scour it.

Brush a generous coat of mineral oil on wooden cutting boards every six months or so to prevent cracking. Let the oil soak in, then wipe off the remainder with a soft cloth.

Answer 2

According to a study wooden cutting boards are safer than plastic or glass the average time of bacterial survival on a wooden board is 3 hrs. versus 8 to 12 hrs on the others . This is because of the tannic acid in the wooden board . Use hot soapy water on it and rinse and dry well . If you put it in the dish washer the wash cycle will saturate the board and expand the joints damaging it , conversly the drying cycle will heat the board up so much that as it's drying the outside will dry faster than the inside again damaging the joints . In other words you'll ruin it . I've been using wooden cutting boards for 35 yrs with no problems .
