Greg Ellifritz, over at Active Response Training posted a great trick for those who have lights mounted on their weapons.
Long training sessions can leave a nasty carbon buildup on the lens of the light which can be darn near impossible to clean completely. His trick? A little ChapStick on the lens. Makes clean up a breeze and doesn’t affect the output of the light in any significant way.
You can read more about this little trick and find out where he discovered it here.
God Bless and have a great weekend!
