I was up on our catwalk yesterday, focusing some of our PARs that we use as rehearsal lights (they were the only form of proper stage lighting we could actually turn on, because nobody was around to unlock the control room, and we had an assembly in a few minutes..) While I was up there, I noticed on some of the handles (proper name?) of the PARs there was this odd, yellowish gunk on them. Is this normal? What could this substance be? Is it harmful?
