It depends on the gun and powder that was used.
I'll use soapy water with some Pine Sol added for cleaning C&B pistols fired with American Pioneer Powder. But usually use a combination of solvents with rifles due to firing other substitute powders that can be more stubborn to remove.
It can require more elbow grease to clean with solvents. 90% of the carbon residue comes off easy, but it's the last 10% that seems to require more effort. Especially to remove it from the nooks, crannies, threads, rifling grooves and where it can accumulate thick around the drum, nipple, lock plate and hammer cup.
I have Rusty Duck Black Off, Hoppe's Number 9 Plus Black Powder Solvent & Patch Lube and Birchwood Casey Black Powder Solvent.
