This question was on another site.
I think I know the answer, just want to post it and see what comments come back.
"""
In speaking with some sprinkler contractors, a comment was made about the glass bulbs in sprinkler heads. The comment was that small scratches could occur if they or cleaned in a method not suggest by NFPA. They said the small scratches could reduce the sensitivity of the bulb to heat. They said this reduction could cause the bulb to activate at a lower temperature than what was designated on the bulb.
Does anyone know if this is myth or fact."""""
