[RSV]

As the title makes clear, I (foolishly) forgot to close my sunroof vent one afternoon, fell asleep, and woke to a torrential downpour. Enough rain seeped in that portions of the headliner were soaked. I blotted up as best I could, then used a carpet/fabric spray shampoo. While it helped, there's still discoloring.

Suggestions welcome.
