KG12 proven in tests to be the best Cu remover. I just hate the way it rolls off the patch when you pour it on. You have to almost massage it in.
Boretech Cu+2 excellent, nicer to use than KG12.
Bore Foam (I use either Gunslick or Wipe Out + Accelerator) very effective on barrels that don't copper up real bad. Back to KG12 or Cu+2 for them. Bore foams used to be the cleaner of choice for Border Barrels when running in. They would leave the foam in over night.
Sweets - threw mine away long time ago. Has been proven to damage SS barrels. Your call if you wish to risk leaving it in your barrel for a period longer than 10 minutes. I’ll not take that risk on expensive barrels that take months to get here and cost reasonable money to chamber etc.
Hoppes 9 - great smell but useless for heavy Cu.
The fowling will be in several layers - copper, carbon. Need to attach each individually. Despite what the snake oil makers claim there is no one stop shop solvent that effectively removes both. Although Eliminator comes close. Need to also use an effective carbon cleaner. I use Mercury Outboard top engine cleaner, or the equivalent Subaru product. Boretech make a carbon cleaner which is probably more human safe!
JBs has its use along with Autosol if all else fails.
Handy if you have access to a bore scope. I have looked down barrels that owners claim to be clean and have seen sheets of Cu still. Next shots just keep building it up.
To check, push a cotton bud 15 – 20 mm down muzzle and you will get a good view. Can use small torch and magnifier to inspect there as well.
Good luck.
