I use brakleen for car parts and all sorts of stuff. Supposed to be great for removing carbon deposits, was also told its good for cleaning the action of semi automatics.
If hoppes isn't very effective for copper removal, what would you recommend instead?

Ha ha that's the 64 million dollar question that comes up on forums. Almost a Holden Ford thing.

I started with Hoppes 9, then Sweets, a host of Yankee ones mostly ineffective, KG-12 plus some others I cannot remember names of.
Currently use Boretech Eliminator but if problem Cu use Boretech Cu+2 which is a dedicate Cu solvent. Also have Wipe-Out and Accerator but almost out of that and cannot locate any more. They also make a bore foam which is effective. Bore foams is another topic again.

If just going for one snake oil buy a bottle of Eliminator. It will also deal with carbon. One bottle lasts for ever. But don't use it to protect the bore in storage.
