I see there are other questions of this nature but I have not found the answer to my question yet, so I am asking a similar question. What object do i use to hold the fans in place when i am dusting with compressed air? Would a Q-tip be ok? I want to avoid static damage. Can I just touch a metal toolbox to dispel static, or metal pipe, before I start working? Should I keep touching the metal object throughout the process? Thanks for any advice!
