I have tried many different chemicals & solvents and none, zero zip, zilch, nada remove hard carbon. Visually inspecting before and after with a borescope.
Elbow grease + brush or abrasive will remove it.
Varget is dirtier than say IMR4064 but I did not think it was that bad loading it in my 308, I just follow my regular cleaning routine with no additional time or steps required.
Another thing is one mans "my barrel is clean" is another mans "Jesus is that filthy" and
then you have the "I only clean my barrel when accuracy falls off" guy.
