My "spit" is the same 1-4 Ballistol-water mix I clean BP with, although a light application of straight Ballistol works well too. I gave up on hot water cleaning years ago while futzing with a .54 flinter.
Going tomorrow, if I can get an appointment, to buy some Old Eynsford for the new musket and caps. Seems many prefer FFF for target shooting even with the .58, so I'll get some to try. Gonna buy some FF too for my hunting rifles.
