Is there better stuff than Breakfree CLP (or the Winchester equivalent) for general used in Handguns and Long guns. Perhaps. Lots of different opinions. But some of that seems to be an effort "gild the lily."
Breakfree CLP does what it should, and unless you're putting your gun through the weapons equivalent of Ranger training, it probably doesn't need to be a lot better.
Is there stuff that's less expensive and more-easily found?
Not around here.
Sometimes "good enough" is more than good enough.
