I would not put them in the dishwasher but wash by hand!

I would scrub them by hand first.

I think so but if in doubt douse it in bleach!

Really interesting comments read on this!

not sure

A hot dishwasher cycle will kill the bacteria on your chopping board.

the heat should kill any germs

Yes because the dishwasher usually uses hotter water than when hand washing.

I think they get a reasonable clean but not as great as scrubbbing. If you have any scratches on the board the dishwasher powder may get stuck in them.

I always put my plastic boards in the dishwasher. They always come out really clean.

yes they will ! !

there are some good comments here

As far as I know it does

It does just as well as hand washing.

I hope so because I put all of my plastic ones in there

yeah i think they do

I know with plastic it is fine to put them in the dishwasher. You can also hand wash them in hot soapy water.

Thankyou for this question, I was actually curious about this as well as I have heard different boards need to be cleaned like this and so on.

Yes they do. The steam disinfects them

I put my chopping boards in the dishwasher and I think they come out cleaner than if I was them by hand
