OKcomputer, the residue you are trying to remove is not water soluble. 
The other component of 50% (70%, 90%) ISO is water. As suggested using higher strength ISO (overnight soak and aggitation) does the trick.
Or, get some Everclear 190 proof (95% grain alcohol)... Some feel better about using Ethyl alcohol, if you are going to collect the wash and evap it for later use.
Another hint on cleaning. A hot, spent load will eject more easily from a tube and leave a pretty clean bowl and screen. Heat the bowl, and do a short draw just before blowing the spent contents out, works much better than doing the same with a cold bowl.

Ted, we have used the same size, small muslin bag, for waste tobacco,
from the same supplier since Day 1 of Purple-Days.
The idea came from using the small bag that kid's gum comes in...
the little 'Miner's Gold' ('Santa's Coal') gum bags...
But, I doubt that they are consistent weight (probably close though) as the draw string length may vary from one bag to the next.

Screens: I don't clean mine, obviously, with hundreds of new screens at hand, I just replace screens.
You can cut your own replacement screens with common scissors.
Access screen material from your local tobacco shop. Cut a disk into 1/4s... ie. cut the pie in half then cut the halves by two. You now have four pieces with a right angle to work from... hold a straight screen edge up to the bowl, count how many wires wide you need your screen, cut a strip that wide. Count the same number of wires on this strip and cut a square. Nibble away at the corners of the square (pre-school style) to make a round (doesn't have to be perfect) screen. Pretty simple, once you have the hang of it... No, this isn't how I make screens, but, when I had an old Eterra style unit this is how I made my own new screens.
As mentioned, with a well fitting screen you do not need the clips and the clips restrict the airflow a bit ... I must manufacture with clips to produce as bullet-proof an item as possible, I'm sure you (the consumer) understand why. As mentioned, without the clips a screen can be dislodged, but after the first bowl, or two, it's stuck in there pretty well and won't just blow out. I never use clips in my own tubes.
