Blast Poweder is a common high-tech degreaser. Have you talked to your local FFL
store if this is the best chemical degreaser?
1) When I prepare my AK mags for long-term storage cleaning process, I first....
-Use cleaner-degreaser like BLAST POWDER
-Silicon cloth wipe down
-Apply Rust Guardit
-Put in Kleen Bore storage bag. Or for short-term put in stretchable Gunny sack.
2) when go to use them (after storage), I use No. 10 Solvent or even copper cutter to get all of the
rust prevention and chemicals off of the magazines. (I believe the back of rust Guardit bottle
tells exactly how to remove the Rust Guardit, but I am 99% sure No. 10 Solvent works here).
