I accidentally mixed PineSol and Bleach in the basin of my sump pump last week and cannot get the smell to subside. Can anyone tell me what will neutralize this reaction? I have read that the mixture creates "mustard gas" and I agree, it's a horribly pungent smell and it's making our family miserable. I've tried rinsing the sump basin with warm water and with the recent snow melt, the basin is filling and emptying with ground water very frequently. Can't imagine how the smell is hanging around?
