Holy Sh*t!

by Bawana17, from CA, United States Written on June 14, 2021
A shame this is discontinued. A one word description: Wow! Two words: Holy Sh*t! This stuff actually WORKS. Fast, easy, minimal elbow grease. Best I’ve found in 40+ years of gun care. NOT a shill! Regular guy, who’s been accused of wearing Hoppe’s #9 as cologne by my wife. Too bad it’s no longer available.
Pros:
  • Best I have ever used
Cons:
  • Discontinued
Best Used for:
  • Carbon removal
Would recommend: Yes
