Best way to remove moisture and mold in car?

I had a similar situation when my truck was parked for about five years. When I got into it scuzz was everywhere. I cleaned up the mess wearing a GOOD face mask and gloves, with bleach water to wipe everything down. Then when it was all clean, I cracked the windows open about a half inch and put an incandescent 100 watt bulb in a cheapie fixture on the floor of the truck. I set it on a timer to come on for two hours daily in the afternoon. Problem solved.
