i'd be hesitant to jump right up and buy a new one because i have had great success cleaning headliners with APC+. just be careful of the APC+ falling from the headliner. dont look up while spraying and dont inhale.
i've been cleaning a few headliners and it is impossible to breathe while spraying. i highly recommend standing outside of the car and spraying up. this may have been obvious to most, but i was a moron. APC+ is not a very pleasant mouthwash. once again this should have been obvious to anyone who isn't me.:bounce
