You can go to the website and read about it but both FP-10 and Militec-1 claim their lube/cleaner has sythetic compounds that actually bind to metal and make a perminant layer of protection/lubrication. They claim it increases barrel life, accuacy, reliablility, and makes it easy to clean.
I use FP-10 to clean (it does smell nice) and Militec-1 to lube. The last time I cleaned my bolt I wiped it with a rag and all the carbon fouling came off, that made me happy. The barrel is much easier to clean now too (bore brush with FP-10, 2 dry patches, and a Militec moist patch and it's shiny).
I liked breakfree, but I really like FP-10 and Militec-1 (it's more like a treatment then a cleaing).
BTW, I'm not selling these products I just like them because they made my ARs much easier to clean.
