Shooting Colt open top revolvers cleaning is easy just make three parts barrel,. cylinder, and frame.
The cylinder goes into a jar of moose milk to soak. The barrel likewise goes into a jar of moose milk.
The frame gets carefully wiped with a wet moose milk patch cleaning all fouling from everywhere needed.
The barrel is cleaned with a proper caliber cotton mop pumping the liquid through several times.
The cylinder gets the same treatment. which is a little harder with the nipples in place, but persevere
Then the bore and chambers are wiped clean with dry patches and oiled with your favorite gun oil.
About every 100 to 150 rounds clean as above, but remove the nipples and let them soak in a small jar of paint thinner. For reasons I do not understand they come out with the cap fouling soft and easily wiped clean.
Now comes the fun part. With good fitting gunsmith screwdrivers remove the back strap, trigger guard and all the little inside parts keeping screws and parts separate. Empty cap boxes work well. With the frame completely stripped blast it clean with carburetor cleaner especially the channel in the frame for the hand. Q-tips work well here.
Wipe all the parts clean. Put an anti-size lubricant on nipple threads put it all back together and

You are done.
It sounds intimidating, but actually when you have all the tools at hand it takes about the same time as field stripping and carefully cleaning and re-assembling that unmentionable side arm designed by a well known gunsmith in Utah 110 years ago (OK Moderator?).
I use moose milk mostly because it giver a twofferit cleans (water) and oils (Ballistol) but plain water with a drop of Dawn will do the same however, after cleaning every thing must be dried and oiled.
This is my way it may not be the best way, it certainly is not the only way, but it works for me.
