I do have a problem with Hoppes.
If you don't get enough of it out of the bore, it will drain down into the action when you put the gun in a safe. This is especially true for break-action shotguns.
I do use Hoppes, but I use a lot of things, including CLP, Outers Foaming Bore Cleaner, Brakleen, Shooter's Choice Shotgun and Choke Tube Cleaner, and a few other things I can't think of right now.
Brake cleaner is fine if you have only the metal parts of a gun, and they're really gummed up. You can avoid disassembling a receiver, for example.
However, you don't want it anywhere near paint, wood, or plastic of any kind.
