Look up Ozone Generators. We use them in rentals. That is what the car dealers use.
My wife's work also uses them in storage rooms with furniture to eliminate odors.
I ran it in the car for about 6 hours. It gives off a kinda bleach smell, but a bit different when running and the car still has some of that bleach like smell in it 3 days later, but it has been closed in the garage. I'm gonna park it in the sun tomorrow and leave the windows open to air it out. There is no trace of mold or mildew smell anymore no matter how close to the fabric or foam you get. I bought the FM-14. It's a bit pricy, but Made In The USA and it's something I'll use in those musty areas of my house. I had some flooding from a broken pipe and just couldn't get rid of the smell left behind completely. I'm confident this will do the job nicely.
Thanks for the tip Oklacarcollecto!!!
