People choose a cleaning method based on which type of powder that they shoot with, how much time and talent they have in dismantling their guns, and which type of gun they have.
Because I use 3F American Pioneer powder which doesn't contain sulphur, I only remove the grips, cylinder and nipples before dunking the Remington frame into very hot soapy water.
Then I dry it and liberally apply mineral oil to the internals and rest of the gun.
I also grease the nipple threads with an anti-seize breech plug grease.
Other folks seem to either:
1. Wash their frame minus the grips & cylinder in soapy water without taking it apart and then heavily oil it after drying.
2. Tear it down and clean it thoroughly.
3. Pack it with grease.
4. Just heavily oil inside the frame.
4A. Some folks have mentioned coating their internals with powdered graphite to help protect them from the fouling, or even saturating the BP fouling with peanut oil.
Real black powder leaves a more gritty, granular carbon deposit [since it contains creosote] inside the action based on how much powder is loaded and the gun model.
Other sub. powders leave varying amounts of their own unique fouling some of which dissolves easier with soap & water water etc... than others.
This is because they either contain sulphur such as BP and Pyrodex which can create an acid, and/or potassium perchlorate which many believe to also be corrosive.
And the carbon residue can absorb moisture from the air or from washing that saturating with oil can help to retard corrosion from forming.
There are some youtube videos showing different cleaning methods, and a thread under "black powder essentials" at the top of the THR black powder home page that describes Gatefeo's method.
The type of powder used can make a difference.

No matter which powder is used, the gun still needs to be cleaned or washed.
Some powders and climates are more forgiving than others and can wait a day or two after being soaked with Ballistol, mineral oil etc....
But this video shows what happens if a revolver isn't cleaned at all.
