Does anyone spray down your hedge trimmers between jobs? I was talking with a nursery owner and he told me that WE as a group are most responsible for spreading tree and shrub disease. He says a simple spray with Lysol or similar will kill germs before moving on. This is something I have never thought about. I do spray with a WD40 type spray befor beginning the day but not at each job. He did not know if this will kill germs or not. Any thoughts?
