Biohazard

Nah...thorough rinse every time. It was actually showing dramatic improvement when I posted that.

Presently: Being certain that victory was close at hand, I pulled the cover off completely and re-treated the entire car with ammonia one more time to ensure that any cross-contamination from dirty parts to clean parts was kicked square in the junk. Chassis, cabin, and engine bay...the whole thing...all at once. I do believe the mold fight is over and that I can, now, get to painting and reassembling stuff.

pending a sniff-check, of course.
