Lets say someone has a salad with feta cheese in a parve bowl and they use a vinegar type dressing. If when they finish the salad there is some leftover some of this vinegar dressing and it stays on the bottom of the bowl for 24 hours, does the parve bowl now become milchig due to the vinegar being a milchig davar charif that was left in the bowl for 24 hours? If not, why?
If the dressing is a davar charif depends on how strong the dressing is. Regardless the bowl is now milchigs since the milchig liquid was left inside it for 24 hours.
