2 other good choices for cleaning the inside are:

1. Brake hones ( used for smoothing the inside of brake cycinders )
Any auto store

2. Shotgun bore bristles. If mounted in a drill, it will clean out
just about anything.
 
Try to use the larger sizes ( 12 guage ) for the larger tubing and
work down from there.

Both work well.
