The Lyman Turbo Sonic Ultrasonic Case Cleaner delivers ultrasonic cleaning action that allows reloaders to clean cases inside and out in less than 10 minutes. Ultrasonic action creates "Microjets" that take off the most stubborn carbon from brass cases, gun parts and other equipment that will fit in the machine. This solution is specifically designed to work with any ultrasonic cleaner. It will remain effective for up to 30 washes and is great at removing stubborn carbon fouling and residue from cartridge cases. While ultrasonic cleaning will remove stubborn carbon and grime from brass it does not polish cases, once cases have been run through the ultrasonic cleaning cycle they will be a dull brassy color. Reloaders looking for very shiny cases will still need to run brass through a tumbler with polishing media if the desired result is shiny brass.
