My end caps are aluminum and I was wondering is Kroil Oil or PB blaster safe on them? I have heard Hoppes #9 is not good on aluminum.

I know that Kroil is safe on aluminum. AAC recommends it for cleaning their rimfire cans.

I've never heard that about #9. I had thought it was about the mildest (safest on a wide-range of metals, plastics) solvent on the market.

SWR recommends both Kroil and WD-40 for the warlock.

I just ordered some aluminum safe carbon remover from orison mfg, one type is for cleaning carbon and powder residue from firearms, the other is a carbon removing dip, that although designed to clean carbon from auto pistons, it is claimed to be non corrossive, ph neutral, aluminum safe, so I'm going to try them on my Coastal Passport suppressor, hopefully it will work, and I'll let you know how it works, if it doesn't and dissolves the baffle, at least they are cheap to replace through Coastal.

Simple green reacts with aluminum and causes it to become brittle. There was a safetygram that was put out by the Air Force back in the late '90's, early 2000's that hade a huge article on not using Simple Green to clean aircraft parts, since there is alot of aluminum used in modern aircraft.
