"This may not be exactly true. BP fouling sucks up water like a sponge, this is how it causes corrosion. As a result its very easy to dissolve and wash away with water. Most detergents, like Dawn, contain salt in the form of sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES). Sodium salt.
Since it does not make the barrel cleaner I see no point.
BTW my hands are not made of steel. They also often have things on them that are not water soluble. Like oil or grease. So I use a hand cleaner with grit when they are really dirty. Not something I would use on a barrel.

Dan,
Sodium Lauryl sulfate and Sodium Laureth Sulfate are not really salts simply because they contain sodium. The chemical formulas show them to be
organic compounds with a terminal negative charge that attracts sodium (CH₃(CH₂)₁₁OSO₃Na). All those C's are carbon and the H's are hydrogen, and that is what makes up an hydrocarbon organic compound. The important thing is that they are organics, not salts, and play little to no part in corrosion. The uncharged end picks up "dirt" and the charged end lets it dissolve in water. The dirt in this case is carbon from shooting black powder. Then the "dirt," sodium lauryl sulfate and water go down the drain together.
My guess, and a guess it is, is that water alone picks up most of the carbon particles from the black powder burn through physical sloshing and agitation, then carries it out of the bore. Carbon is only sparingly soluble in water. The SLS detergent actually solubilizes some of the carbon that is not picked up and sloshed out of the bore by water alone and you end up with a cleaner bore.
There are some ways in which residual ions from black powder could tie up the charged end of the SLS and it would no longer go into solution in the water and it would leave a film - the analog to the famous household disaster mentioned in detergent adds in the 1980s: Ring around the collar.
I am no where near as experienced with black powder as most of you, but I haven't noticed any deposits in my bores.
And, as some already have said, we really can over think this topic. Thank goodness I am not guilty of that.
