When you do clean your shotgun, do you keep going until the barrel patches come out 100% clean?

OR, do you just clean until the bore is shiny, and the patches still sjow some discoloration.

Unless I plan to store the shotgun for a long period, I usuall do the latter (good enough?).

If I want the bores to be 100% spotless, I leave bore cleaner in overnight, and finish the next day. Probably not necessary, and perhaps OCD...
