I tried a Maguires Air freshener type AC cleaner once, that was the worst product I have used. The car stank for weeks.

The spray foam that comes with a long thin hose for inserting in the air vents, and reaching down onto the evaporator usually works well.
Kills the smelly bacteria that reside on the evaporator.

I have used other brands of air freshener type AC re-freshener , it was only the "maguires" brand that stank.
