I appreciate you doing this experiment. It should keep you occupied for the winter. 😇 👍😍
Got tired of reading all the opinions of "the best" copper cleaner, so I decided to see for myself…this way I have something to compare each to. I almost always use Sweets and/or Hoppes BR , but open to knew possibilities.

I can relate to that. I've used all that you are testing; they are good stuff. I also use the foaming version, and they work as well. I like using them on a vertical barrel, they slowly flow as a self-timer. 😇
 
Picture after one day…BoreTech changed colors

Barnes cr10 is thorough and fast…and dangerous according the warning!

1) I use a couple of Wet Patches of, Barnes C-10 and, WAIT 15 Minutes ( Go have Coffee ! ).
2) Then, I use a couple of Wet patches of Boretech Eliminator for, Carbon Removal,.. in throat ( Wait a Bit, w/ Coffee again )
3) Brush w/ Bronze brush in Throat area, several Strokes, using,.. BT Elim.
4) then down Barrel with, One more Barnes C-10 on Patch,.. to push,.. everything, OUT !
5) Dry, and Oil with Montana Bore oil, then, Dry,.. AGAIN
Yup kinda, a PITA but, "Works" extremely,.. Well.
Old School cleaning, "Modified" for Me, as I Hate cleaning Guns But, this Method really gets,.. it DONE for Carbon and Copper !
