Subaru dealer's in MN sell a kit to kill the "old man winter" smells... look into what they use? im sure its on the internetz somewhere.

 

The way that might help avoid this is before shutting the car off turn the ac off for a minute or two and just run the fan on high, it is supposed to help dry everything off. I do this on all my cars and I have never had a problem.

 

That's a good idea. I notice that after I kill the motor and put the key in "accessory" mode, if I had the AC running, then the air coming out is still cold for a few minutes. Eventually it stops being cold. That must mean the condenser has lost its cool. But before I can start following this advice, I need to get rid of the mold that is there right now. Can anyone tell me if Frigi Fresh is a perfumy cover-up, or does it kill mold and then leave no lingering fragrance? I just can't deal with perfume.
