I did a brake flush using Pentosin's Super Dot 4 brake fluid a couple of days ago. The old fluid was a dark bluish green color. And I know it hasn't been changed in at least 3 years since that's when I bought the car. Could It be that the previous owner used that Super Blue stuff? I never had any clutch squeaking until today that I noticed it. It does it both when the car is on and off.

Anyone know how to flush the fluid for the clutch?

 

Super blue is known to cause a squeaky clutch pedal.
