Hickory Stave mold?

on about 10 of 30 staves guess I better start reducing

Wonder if a dilute bleach solution would cure my ills.

While bleach can kill the mold itself, it is not the solution to the problem. Mold spores are everywhere; they float in the air. If mold starts growing on your wood, the humidity must be too high. Simply lowering the humidity of the air, for instance by moving the wood to a room that has a lower humidity, will solve all your problems. Some airflow will also help, so the surface of the wood dries quicker.

will a vinegar wipe help in a situation like this? I know a lot of people use it to kill mold on meat.

I had laid the staves down after a week. went out yesterday and stood them up and separated them, should increase airflow.  Down to 43% humidity today.

I have had this happen to hackberry staves when it was real humid. They turned all greenish and looked like big cucumbers,  . They were fine though. Just one swipe of sand paper and the stuff came off. All made very nice bows. This was with staves that were propped up, upstairs inside my house though, not outside or anything.
