Laser Guard 'Powderization'
Hello...last night I noticed that the laser guard had some 'powderization' on the lower internal surface. It looks like the inner particles of the laser guard are 'moving' towards the beam. It reminds me of 'iron filing on a magnet'
I cleaned it by dusting it off with a paint brush and then rinsing it under running water.
I was wondering if anyone else has noticed something this on their laser guard.
Am I doing something wrong? What could possibly be the reason for this occurrence?
Any insight on this would help.
