My car was left in a damp garage for a few weeks and developed this hideous layer of mold over the complete interior of the car. I mean every square inch!

I had the car detailed which got rid of all the visible mold but the car still has very strong moldy smell to it. Even when the windows are open the smell is overwhelming.

Now I have a kid and I need to make sure the car is clean and safe for him. Any ideas?
