Hey guys/gals
I have a x200 and a x300 mounted on a g22 and a G21. I am taking a class at the end of this week ill be doing 1000 rds in 2 days,including night fire. How do i keep my lenses clean and still usable for the night fire portion?
Thanks
Roy
Wipe it off before you reholster.
Car wax or Vaseline.
One may be able to keep the SureFire “window” clean by using Winchester’s WinClean ammo. 
Reading this makes me wonder how many folks will spin the business end of the firearm around to look and see if their light is dirty… :rolleyes:
thank you got M4 ill try that
Crazydj not many people will… but being as it is a low light class it would be great to see what im shooting at.
It really should not be an issue since the lens if mounted far to the rear of the muzzle. In the unlikely event that lens gets so dirty that the light becomes ineffective, you can simply wipe it.
Took a class recently and the things people did ranged from Blue painters tape on the lens during the day, Vaseline, soak and clean with Hoppes #9.
I meant of all the folks out in the shooting community. I forgot to say, “present company excluded, of course” 
As been suggested here before and “abroad” on the net, one can use an eraser to wipe the “window” clean from the SF.X200/SF.X300.
If the eraser doesn’t work, try a very mild abrasive, like toothpaste.
I put a piece of electrical tape over the lens when not shooting at night.
+1. easy to apply and remove, and very effective. quickest and best fix yet.
I simply place a drop of weapon oil (Militech, 10-8, etc) on the lens and rub it evenly across the surface with my finger. When I’m finished shooting I wipe it off with a rag.
I thought the adhesive comes off and makes a mess when hot?
This is also what I do.
Me too! Works like a charm and it’s easy…I’m all about easy.
