Wow, very interesting pics.
Congratulations, you are the first person to figure out how to turn their clutch fiber plates into (literally) ugly black pasty goo.
Kinda scary, actually.
Can you tell us what you used to do it? Be nice to know, so we can tell folks in the future what to avoid.
Did you spray any "stuff" on it as per WD's advice ??? This might not have been the best thing to do to your fiber plates as when I sprayed brake parts cleaner on my clutch accidentally it slipped some for almost a week before settling in again.
Remember, fiber plates are a pressed together composite of cork and hard fibers, held together with hard setting rubber type thermal compounds.
You might well be able to dissolve the bonding agent if you start spraying large amounts of "stuff" on your clutch pack.
Death by spray can .... need to add that to the list of clutch killers.
Change your oil and oil filter -- you have all sorts of fiber stuff and rubberish stuff floating around in your oil and contaminating/blocking up you oil filter paper element.
