There are more gun cleaners on the market than unfulfilled election promises. Most of them are advertised as having the ability to clean the dirtiest of guns. FireClean, a combination cleaner and lubricant, takes a different approach. Rather than just cutting gunk, it also is said to prevent gunk from accumulating in the first place.
I found that FireClean does meet two of the most important criteria of a firearm lubricant: It sticks to the metal, and it’s effective at high temperatures. As a general-purpose cleaner, it worked especially well on carbon. The difference is that, unlike many cleaner/lubricants, it does not trap the gunk–it repels dirt and powder residue. After a couple of applications, most of my cleaning chores consisted of wiping rather than scrubbing.
I’ve been using FireClean for over a year on my MSR-type rifles and suppressor-equipped guns. Both collect carbon crud rapidly and present tough-cleaning challenges. But after a couple of applications, any carbon residue that does stick wipes right off. I use it on MSR bolts and carriers and suppressor mounts and pistons.
