Yeah, an old fellow sitting outside my apartment who saw what I was doing was talking about how it's impossible to get the mold out of something like an A/C unit, because it's all around the coils and such.
I guess I'll just have to keep a can in the trunk or something. Maybe, since it's such a common problem, we could approach Hyundai USA, and if they don't listen, in true American style, go class action on them. (Like they need another class action lawsuit).
How did someone determine that it was definitely mold?
