You are shooting more often than I do.
Solvent - Outers, Hoppes, MPro 7... it doesn't seem to matter.
Oil - Outers, Hoppes, Breakfree CLP... again it doesn't seem to matter.
Proper fitting bronze brush is something I do care about.
Bronze or aluminum cleaning rods, or the nice plastic one that came with my CZ 85B.
If I get solvent on anything other than what I intend, I wipe it off and then clean that spot with an oily rag.
I have used engine oil to clean the barrel as well. Worked fine.
When I clean the barrel if the last clean patch is completely dry I will put a drop or two of oil on it (only a drop or two) and run it back through one more time.
Cleaning is something that can get over board. My personality is such that I can over do it. My brother has guns that have never been cleaned and they are just fine. It has become mandatory to see how long this can go. Yes, it is wrong. The barrel on one is pitted with rust (a rifle) and it still shoots 1" groups at 100 yards. Go figure.
In my opinion there is too much hype about gun cleaning products in general. As sure as I say this there are surely some products that should be avoided.
Common, name brand stuff, that has been used for 100 years, tried and true, that is a safe path.
What does your pistol's manual say to use?
