You can use a turkey baster to remove the fluid in the master
cylinder...then, refill it with clean/new brake fluid. This way, you
already get somewhat of a cleaning. Here's the procedure on the two
different ABS systems.
If you have Rear Wheel ABS:
Bleed only one brake component at a time in the following sequence:
Master Cylinder
Combination Valve
Rear Antilock Valve
Left Rear Wheel
Right Rear Wheel
Right Front Wheel
Left Front Wheel
If you have Four Wheel ABS:
ABS system bleeding requires conventional bleeding methods plus use of
the DRB scan tool. The procedure involves performing a base brake
bleeding, followed by use of the scan tool to cycle and bleed the HCU
pump and solenoids. A second base brake bleeding procedure is then
required to remove any air remaining in the system.

No, I did not drain the master cylinder. I didn't want to run the risk
of introducing any air into the system. I just kept it topped off as I
used a vacuum pump to pull the fluid through the system.

Cool. I took a look at my FSM last night and it talked about draining
the master cylinder and one other item before going to the wheels... Did
you do this or is this only when rebuilding the system/replacing the
master cylinder? Tom <unsnip>
