Woodworker here: This is why wooden cutting boards are coated with an ingestion safe oil or paste wax before use. Prevents significant fluid ingress. Then hand wash it and stand it vertically to air dry.

I just wish my partner wouldn't leave wooden chopping boards or spoons soaking in water overnight. Want to get a somewhat decent one but I know it's inevitable.

Maybe I should just buy some nice hardwood board and cut one to size and use that as a choppig board. A lot cheaper than buying something labelled as a chopping board.
