Just saw your post. Yes 50/50. I will say I didn't really measure it, just sort of eyeballed it into an oil can.

I've not seen anything bad written on how the detergent reacts to the finish or the aluminum, couldn't really think of anything myself, so I just mixed it and oiled everything down, BCG, trigger, and soaked some around my gas block (adj. SLR) when I had my forend off to keep the set screw on it from freezing up.

Like I said, my guns don't get run hard and are not duty weapons, but after 200 rounds, suppressed, all the gunk (and there's quite a bit of it), wipes right off.
