Asked and answered two weeks ago, search for cleaning rituals, the following was my reply then
This is for cleaning a flintlock with a pinned barrel.
First you must have a pattern makers vice on one end of your bench and a support on the other for the stock.
Clamp the buttstock in the vice while the other end is supported, remove the lock using gunsmith specific screwdrivers.
Using a pin punch with a concave point made especially for removing barrel pins, tap the pins part way out and using flat face pliers remove the pins and then using gunsmith specific screwdrivers remove the tang screw.
Inspect the pins and straighten if needed by tapping with a jewelers hammer while on a perfectly flat surface.
While the stock is in the pattern makers vice stick a dowel rod in the barrel and gently pry up while pushing down on the stock, careful so you do not crack the stock.
Remove the breech plug and the vent liner, clean both thoroughly.
Scrub the interior of the barrel with your favorite gun cleaning juice until the white cleaning patches are spotless, oil the barrel inside and out with Ballistol, tell the wife the cat farted
Completely disassemble the lock, place the parts in a fine mesh bag and run the securely fastened bag and parts through the dishwasher, promise the wife you will not do it again while her good dishes are in there.
Rub all the lock parts down with Ballistol (damn cat) and reassemble. You probably should have already ordered the replacement fly for the lock by now.
Coat the bottom of the barrel with a good paste wax, apply another coat of polyurethane sealer to the inside of the barrel channel of the stock to keep moisture from penetrating.
Reassemble and apply a good coat of paste wax to the entire gun.
And that is how YOU should do it, I do it like the evil Mike Brooks (Comfortably Numb) does and have for forty years. This will mean you new guys will go do something else to avoid the hassle instead of shoot BP which means more BP, flints etc. for me!
I fill the barrel with water with a toothpick in the vent. Let is sit for 10 minutes and pour it out. usually add water again and pour it out immediately. Then a couple dry patches followed by a couple Windex patches then dry with a couple more then oil. No real time involved at all. For BPCR I just use maybe four Windex , a couple dry and then oil.
I never ever remove a barrel for anything other than to change a vent liner every 5 or 6 thousand shots.
