I'm using frog lube too. It's not a good cleaner on a gun that you didn't treated with frog lube first. When I get a gun that was not treated with frog lube before, I do first a full cleaning with a good regular gun cleaning solvent. Then I remove all trace of lube with rubbing alcohol. Then I do a frog lube application with heat. After that, all the next cleanings are a breeze and I just use frog lube. I've seen that frog lube is now selling a solvent that they recommend for this initial cleaning before applying the CLP.
