I came across this sometime ago and thoughtI would share this. It's a test about cleaning supplies vs. rust that occurs. I thought Cayugad did a similar test at one time. I'm always asked at the range whatI clean with, this can clear up any confusion as what to use in case you are a newbie at this sport.
