Baket kaya amoy vinegar or smelly socks ang aircon ng innova namen?

Nag pa toyota aircare last week. It reduced the smell. But not totally eliminated it. From 10(very smelly) went down to 3.

How can i totally remove the smell?


A more detailed info about the problem.

Every time the car start and turned the aircon (ac on with 22 temp setting, recirculate on , 3 fan setting, Rear aircon off.), after being left for prolonged period. A powerful vinegar or a week worn socks smell. ( i have to open the window just to reduce the foul odor.) But after driving about 10 to 20mins it either vanish or i have adjusted to the smell.
