When I was shooting a lot of Black Powder revolver, the routine was to use spray "lube" at the range and head for home.

There, the guns would be stripped (usually one at a time) and immersed in HOT soapy water in the stainless-steel kitchen sink. (This was a bachelor pad at the time, as you may have guessed).

A good work-over with bore brushes and a toothbrush ensued, followed by a boiling water rinse.

Then a quick shake to remove most of the water and a blast with the hot-air gun (paint-stripper grade).

Thoroughly sprayed with one of the "Teflon" lubes, reassembled and put away, usually still warm. There was a Beatles song about that, as I recall.......

And these were STAINLESS BP revolvers.

"Blued" guns could be done in a similar fashion, but you had to be a bit quicker in the "rinse, dry, oil" phase or rust was a real possibility, especially here in a soggy, steamy Queensland summer .

I used to then simply "de-oil" (Carby cleaner), the cylinder / nipple assembly interiors before firing, to avoid contamination of the caps or powder.
