Yeah, as others have confirmed, this is definitely caused by constantly running your system on recirc because it allows bacterial to grow. Whenever I get in someone else's car and I notice the smell, they always have the recirc permanently turned on. Those same people will also sometimes turn the system off entirely b/c of the smell or set the fan at the lowest setting which also makes it stagnate. For this reason, I never use recirc unless it is really necessary and my cars never get that smell.
Fortunately, it is relatively cool where you are this time of year. I would recommend also running fresh air with the A/C turned OFF entirely at a higher speed (doesn't need to be max speed, but close to it). This will also help speed up getting rid of the smell. Even if you don't bother to use Lysol, if you constantly run fresh air with no A/C, it will eventually get rid of the smell but will just take more time.
One last tip - when you do use A/C, at the end of your trip, I also recommend turning off A/C and just blasting fresh air at full speed through the system for about 30 seconds before you turn your car off. This will also help purge some of the moisture out of the system at the end.
