The Hoppe's Elite cleaning line was designed with the active hunter and shooter in mind. This high-tech, odorless technology outperforms the standard cleaners and oils on the shelf today. Hoppe's Elite Gun Cleaner not only penetrates down to the steel's molecular pores while cleaning carbon, copper and lead contamination, but it also conditions the metal to prevent future build up. Hoppe's Elite reduces your gun cleaning time up to 80% with regular use and it is odorless, biodegradable, and non-toxic.
