Until Cayugad answers...

...I use his mix both at the range between shots and at home cleaning at the end of the shooting day.

However I have a flintlock with a full stock. The barrel does not come off of the stock, so using hot soapy water would be difficult. "Cayugad's solution" works very well in my case.

When cleaning at the end of the day, I'll run a fewISO/Windshield patches down the barrel to break up the fouling using either a cleaning jag or the "Kleen Bore" rod with the hoop attachment. Then a soaked brass brush. Then repeatedpatches of the ISO/Windshield mix until they come out clean. Run a few dry patches to help facilitate the drying process. When I am sure the barrel is completly dry and the patches are coming out white, I'll soak a patch with some oil and run that up and down the barrel to give the inside a lite coating of oil.

Then on to the lock...

Hope this is of some help.
