I cleaned the front drains with string trimmer line. I tried to feed the line to the rear too, but I could never tell where the drain was. I then tried feeding the line up from the bottom. Even so, sitting in Atlanta traffic for an hour in torrential downpour, the sunroof began to leak down on me. I got my hands on an endoscope and fished it back a little over a foot:
I hope this helps someone, I still couldn't figure out to clean the drain. I wound up pouring a cup or two of bleach through it.
