I had asked Whip Appeal Neil about a problem my gf is having with her A/C (1998 BMW 328i). After running the A/C for a bit it starts to stink. I also noticed this in my friend's car (2006 Toyota Camry). He suggested I get an aerosol and use that but do I just spray that directly into the vents. Just wanted to make sure there aren't any other things I should be doing.
Thanks in advance!
