Default What is the best A/C flush solvent?

I am renting a flush gun from Auto Zone, and using my friend's air compressor, so what is the best solvent to use to flush the evaporator and tubing?

The three I have found are these:
FJC 2032
Murray/Four Seasons 69991
Interdynamics CQS-11.

Why do you need to flush it? It is impossible to flush todays condensers. The lines yes you can flush.
