Thumbs up on your choice of firearms!
I have used rubbing alcohol as a quick once-over cleaning when planning to continue shooting, especially the bore.
Used that method a lot back in my early days. Only on patches, though.
Using 3F blackpowder, I can fire my Colt Army or Navy revolvers virtually all-day, with no routine, or intermittent cleaning needed.
Today, my typical end-of-day cleaning is to place cylinders in a wash tub & run a bore mop through chambers and bore. Navy Model revolver clean-up quickly.
Many have a pet lube, but good-ol' WD-40 is as good as (if not better) than any other product for application after a water-based cleaning of black powder firearms...cost is pretty reasonable, too.
Not mandatory, but...an air compressor is useful to blow water & excess lube out of the cylinder and you can apply oil/solvent (not water-based) to the internals and blow excess lube & BP fouling out. Tip - wear a work apron.
