Soft and Sticky Clutch

[CowPimp]

A month or so ago I had my master cylinder replaced because it was leaking. I also took the opportunity to very thoroughly flush out the clutch hydraulic system. Now, the clutch is soft and getting stuck again. I popped my hood. The fluid is full, but it is dirty. I'm talking almost black. I definitely have to bleed it again for a short term fix, but is there any reason why it might be so dirty in a short amount of time?

The only thing I have really thought of check was my slave cylinder. Nothing is leaking down the firewall on the inside of my car. And a visual inspection of everything related to the clutch system from above yields no evidence of leakage (And the fact that my fluid is still full, just filthy).

Unfortuntely, according to my mechanic, the dealership gave me a defective master cylinder. He showed me that when he would pump the clutch some moisture would build up on it. Thankfully they warranty their work, so I get the reinstallation done for free. Hopefully I can get the dealership I bought it from to exchange the good one for me. I suppose I will also change the slave at the same time.
