what do you all use to clean gun parts? i mean the small inaccessible parts of the action, not the barrel. i was using birchwood casy brand Gun Scrubber in the aerosol can, but i ran out late on a sunday evening, so i used some brake parts cleaner i had in the shop. what, if any, is the difference between gun scrubber and brake parts cleaner beside the price? they both clean good and dry fast and both will take off any paint or varnish finish on wood or metal. is there something else i am missing that would be better for 'power' cleaning small areas on an occasional basis? thanks.
