The U.S. Army likes to field test equipment and materials by having students at the Ranger Course wring out proposed items.
Usually, the unlucky students will be handed something (prototype widget) and told to use it until course completion or complete failure of the item (whichever comes first).
In 1978, my Ft. Benning class was told to completely clean our weapons (dry solvent pressure cleaners and boiling water in 55 gallon drums), and then apply a new mystery lubricant/protector to all weapons (M16A1s, M60s, & M14s). We were given very specific instruction on exactly how much to apply and to what parts. We were then given tiny little bottles to carry to the field and instructions to NOT CLEAN OUR WEAPONS AGAIN UNTIL COURSE COMPLETION. The only thing allowed in a patrol base was for us to shotgun and field strip the ARs, hit 'em with shaving brushes to remove sand or dirt, and drip more of the fluid onto the parts and components. Run a patch down the bore (liberally soaked with new lubricant), reassemble,...and call it good.
We were not even allowed to disassemble the bolt carriers.
We dragged our weapons thru the next 8 weeks of rain, dirt, blank-fire carbon buildup, mud, swamps, sand, and saltwater.
Weapons worked, rust was not a problem. The product was BreakFree (CLP)...and the entire military began using it the next year. That experience made a CLP believer out of me.
I haven't bothered using anything else since. It is not a great solvent for cleaning but gets the job done with a modicum of elbow grease. For stubborn carbon buildup, I still use something like Hoppes.
The RIs (Ranger Instructors) hated our entire class and thought we were "gettin' over" due to the weapons cleaning prohibition. They figured out other forms of unpleasantness to occupy the time we were normally supposed to apply to weapons maintenance.
When I was raised up to guns (before the Army), lubricant was gun oil and cleaner was solvent. CLP does a good job of both (plus rust protection) and was expressly designed to hold up thru high rates of fire by automatic weapons. Great stuff...
