Folks,  I should have added, the current trend with serious black powder shooters and those using corrosive primed (usually military surplus) cartridges is to use Windex first.  It gets the black powder fouling plus primer salts out of the barrels.  Tim.

Tim that is all new to me. Again very interesting. Appreciate the replies. 

  

I learned about it from Mike Venturino and he mentions it in his books. I use Windex with ammonia and I generally dilute it 50%. Some BP shooters use a Moose Milk recipe involving Ballistol and water. For the cases I drop them in a jug with water and a bit of dishwashing liquid. When I get home I brush them out with a nylon brush, deprime and agitate/rinse a few times until the water runs clean. For REALLY clean brass I let them run in a hydrosonic cleaner for awhile. Then I’ll rinse and dry them in my oven and run them in a vibratory media cleaner and they come out shinier than new, inside and out. Takes a few hours to clean the brass, takes about 15 minutes to clean a BP single shot cartridge rifle with Windex or Moose Milk. Nylon brush with either water base solvent, 2-3 patches with solvent, 2-3 dry patches and a lube patch. Done!
