sharps4590 said:Hoppes #9 Plus, the original, is not intended for black powder. It's mostly ammonia and is great for copper fouling and smokeless powder fouling and not bad for lead fouling.
Given the more than lengthy diatribes regarding cleaning a muzzeloader this has been a most amusing thread. Thank you for posting your question.

Hoppes has made many variants of Hoppe's No9 solvents for cleaning/protecting various centerfire cartridge type firearms.
Hoppes also makes a product called "Hoppes No9 PLUS BP Solvent & Patch Lube".
It is made specificlly for use with the blackpowder firearms environment, and is one of the most outstanding BP solvents & patch lubes I've used so far.
