Odd moss-like/mold-like substance in car
We have a car that has been sitting in our garage over the summer. Since May this vehicle has just been in this enclosed garage with the windows and doors closed. We live in the northern Midwest – it has been a fairly normal summer with some humidity to be sure. Today we opened the doors and saw all of this. It is mostly on the soft material surfaces such as steering wheel, seatbelts, cover of the gear shift, some on the seats. There is none of it on the floors, seat backing (also cloth) and most of the seats are untouched. There is a small amount on the dashboard. Can anyone help me understand what this is, what happened, where it came from, and most importantly how to avoid it?
