Hoppes No. 9 Solvent has been around for over 100 years…since 1903. And it is still around today because it is very effective and people like it.
Hoppes No. 9 Solvent will loosen and remove carbon fouling, powder fouling, copper and lead fouling plus any type of lubricant like oils and grease. It’s very easy to use. Just apply a liberal amount to the area to be cleaned and let it soak for about 10 minutes (for carbon barrel fouling). Now wipe or patch until clean. For gun bore metal fouling, use a bronze/phosphorus bore brush to loosen metal fouling then patch until clean. Gun actions and exteriors can be wiped clean and then lubricated. No soaking required.
I tested Hoppes No. 9 Solvent in a gun cleaner test a few months ago and it did very well. The test consisted of burning 3 charges of smokeless powder on a piece of metal and then applying a gun cleaner. After a 10 minute soak, I attempted to wipe the carbon fouling off. Hoppes No. 9 Solvent loosened the carbon fouling which made it easy to wipe it off with a clean patch. No scrubbing or brushing. It’s that simple.
