Hi folks,


I'm looking for ways to increase the working life of the mic packs and headsets in use at a chain of fitness studios. The classes in which the headsets/packs are being used become very humid, mostly from sweating humans, which is occasionally exacerbated by A/C issues. Currently the SOP is to spray the mic pack connector (T4, Shure ULX1) and the end of the headset (Shure WH20) with contact cleaner once a week and exercise the plug into the connector 15 times after spraying.


However, I'm noticing there is still a significant level of corrosion building up. I have suggested to some that it might be a good idea to spray the connections gently at the end of each 45 minute class. Mic packs are rotated, but sometimes one may end up being used back-to-back.


Are there any dangers to using contact spray this frequently, as long as the unit is powered down?


Thanks.
