Bro, it depends on how dirty it is! My car has only 100 kms on the clock and that too with A/C on. Barely any dirt.
Both Megs quik interior detailer and turtle ice interior care have mild cleaners which help in cleaning the interior. You dont find these in Megs hyper dressing so you should clean with apc first and then dress the interior.
If the interior is extremely dirty like the corolla i did a few pages ago, then you'll have to clean with apc first and then dress it. In short Meguiar quik interior detailer is an AIO (all in one) product..
