White Lightening is a good product. As it's been said, it doesn't work equally well on all folders. It does tend to migrate dirt out of pivot areas. WL is perfect for slip joints and most lock backs. It completely rejuvenated a gritty, stiff Victorinox that I thought I had ruined after a summer of archaeological field school. I had washed it, WD40, forced air, you name it, it was still tight. The WL cured it completely. WL really gummed up my Umfaan, though, so I switched back to the CR Knives grease. I think the tolerances were too tight.
I put White Lightening on my Military over a year ago, and it is still really slick and smooth. I believe it is the combination of the WL and the teflon washers. They seem to compliment the other's performance IMO. On the other hand, my Military has been pretty smooth since I got it, but the WL did improve it.
If you have taken your military apart and cleaned it and it's still gritty, there might be a reason to send it to Spyderco for evaluation.
