Mold must be mechanically removed - you can't kill the spores with anything that won't kill YOU. I have fought mold in a car interior (and on some military surplus goods) and the best thing is just to get a carpet extractor and some Woolite (for the pleasant smell and do it about ten times in a row with ALL the upholstery, etc, exposed, until you can stand it. Dry thoroughly between extractions with fans. Mildew CAN be killed with mild bleach as it is more of a "plant" - but the mechanical removal here is the best deal as well. Good luck to you - you are in for a fight ....
