I was gonna do both, clean the extractor and swap out some springs. Dental pick is a great idea...I was thinking to pry it ever-so slightly with a screwdriver and slide a paper clip down in there to remove the gunk. Been busy and won't get to it until later this week, maybe the weekend.
I would be careful with the screwdriver prying trick I scrape it dry first. This keeps the "wet" carbon draining down inside the slide.
