What is this black stuff in my clutch reservoir?
42k miles, changing out my fluids and when I took the cap off the clutch fluid reservoir I saw this.
Any idea what it is and how do I clean it?

I just vacuum bled in new fluid and it didn't really go away. Old fluid was brown, new is clear.
If I agitate the black stuff it'll move. Should I stick a brush in there?

Doesn't float, it's just at the bottom. The new fluid is clear though.

It's rubber worn from the piston seals. No worries.

Happens all the time...I use a q-tip and swab it clean when I do a flush. Still doesn't clean things beyond the reservoir though, so there's probably no point in doing it, other than it making you happy.

I stirred it up really well before bleeding. It's all gone afterwards.
