Bought some on sale from Midway for some tougher bore cleaning jobs. Anything I should be concerned about besides not using a bronze brush (using nylon instead)? Read something about not using it in stainless barrels is that true?

Tried a pint and was unimpressed. Did not notice that it was better ot worse than #9, or Shooters Choice, or Hoppies elite. Amonia smell is very strong initially but seems to have toned down some. Is it getting weak? Dunno.
