You can use amix of water soluble machinst oil and water to make a batch of moose milk and it works and as a patch lube for target shooting w/roundball. Also a Simple Green and water mix for cleaning works 1 to 2part could maybe go as strong as 50 /50. I have used mainly cool water in my longrifle I plug the flash hole and pour water in till its full and let it set for 15/20min not fancy but it works
