BLB 97 Formula

I seem to have what appears to be mold actually growing or eating away at the body trim that runs along the length of the car, the small body pieces that are half-way up the door and protrude out a little on my 97 Formula
Its very splotchy with dark areas and rough spots on the paneling. The paint is getting dark almost black in some areas. Not sure if the clear coat is gone or what. Wish I had a picture to descibe this one but if anybody has any advice or help here let me know.

A very mild solution of bleach. A cap full in a quart of water or any commercial cleaner that has bleach in it, like a tile cleaner, diluted.
