Was looking around at different cleaners and I know Ed's Red is a excellent carbon cleaner in bolt carrier group.
That being said I don't remember anyone as ever having tried WD40?
I know Mobil 1 0W20 motor oil is very good at keeping the carbon soft by adding a couple drops in the port holes. I will probably stay with Mobil 1 but was just wondering if anyone had ever tried WD40.
