@sjjs....just use a bronze brush with Hoppes (sorry not #2 s/be #9) or any other copper solvent rarely....I suggested that as an experiment to be left overnight as Hoppes will do no damage to a bore unlike some solvents. It was to demonstrate if mainly carbon fouling was still present after cleaning indicated a clean bore. The best method is to use a carbon remover with a bronze brush. It is not a carbon solvent as carbon is indestructible so the product needs to agitate the carbon molecules and separate them from the other burnt residues and the barrel steel with a brush. Those products should not be left overnight in a barrel.

To avoid false positives from copper solvents use only those solvents with an aluminum jag etc (as mentioned above) and patches...there is no benefit to brushing with copper solvents......try a cotton bud in the muzzle end with something like Boretech for example and you will see it disappear before your eyes.
