Changing clutch fluid?

[Zesty]

My clutch fluid is looking pretty black/dark, and I was looking to change it out.

I have heard of simply sucking the reservoir out with a turkey baster or something similar, and refilling with new brake fluid. Not a full flush, but to kinda refresh the fluid. I was about to do that, but figured I'd ask here first, if there is a simple way to swap all the clutch fluid out.

Also, is there a section on this site with "How-to's" as far as changing all the fluids and such? I'm looking to change the clutch, brake, and power steering fluids.

Thanks in advance.
