are the coffee grounds carbon?

I've never done this, so that pretty much defeats any value to anything I say on this topic, but... I was assuming the coffee grounds were some kind of solidified organic crap, not predominantly carbon itself (obviously organic compounds contain carbon, ha)... Ie something kinda cruddy to dissolve, but soluble... with the screen out of the car, it wouldn't be hard to try some heavy duty solvents (eg the brake cleaner suggestion)... but I'm not sure I'd want to pour some of those things in an engine even if it wasn't to be run... there's gaskets etc that might be at risk, no? and even so, you'd probably want to flush some oil through there after...
I guess I would want to be cautious to not end up with more than just dropping the pan as a project!
I think Anders made a reasonable point just a few days ago iirc that running those cleaning products may clean stuff off the engine that was pretty much permanently there (and possibly innocuous enough), but then have it all end up in the screen too... and the oil starvation due to a clogged screen is the bigger issue...
you know, I'll stop typing and let Anders answer this better. see link!
