The only reason I can think of would be if the mic is in an area with lots
of particulates in the air, like smoke. Leaving the polarization on will
not hurt anything but if there is any amount of junk to be pulled from the
air and adhered to the insulation of the microphone that might mean you'd
need to clean it sooner, but that's a really long shot.
