Hoppe's BoreSnake Shotgun Bore Cleaner
Hoppe's BoreSnake is the fastest bore cleaner on the planet. One pass loosens large particles, scrubs out the remaining residue with a bronze brush, then swabs it all spotless with a cleaning area 160 times larger than a standard patch. Add a few drops of Hoppe's No 9 Lubricating Oil or Hoppe's Elite and your shotgun is ready for storage.
