I suspect that most of these products may be cleaners rather than solvents despite what they are called. Anyone really know?
You now know as much as anyone does about these things :-) There's a heap of advertising done to make you think one cleaner is better than another, but I've never found one that really seems significantly better or worse, unless you account for the smell. Hoppe's does stink, so maybe it's better :-)
Unfortunately, of all the things I've tried, none have just magically rinsed away the lead deposits. Even soaking and scrubbing doesn't usually work that well for me. Hopefully, someone will list their secret, guaranteed to work solvent, so I can buy some.
Good luck,
Rusty (safe full of pistols, but can't remember where the range is)
