For those of you with the rear spoiler have you noticed that the hatch an window get to be less dirty because of the rear spoiler ???

Thanks for your response.It will, the spoiler breaks up the negative pressure behind the car if the spoiler curves down the back.
Agreed, our '12 Focus was terrible so I'm reluctant to install a spoiler on the BS unless I'm really convinced it will work.If it's anything like my Focus ST... does nothing at all to stop snow and dirt buildup on the back. Makes it much harder to clean though.
Yep, it sucks snow up off the road for sure.I'm assuming the spoiler makes the back even dirtier. The effect would be to shield the top edge of the car/window from the airflow. That creates a low pressure area that sucks in stuff both over the spoiler lip and up from below. That's why things don't fly out the back of an open truckbed.
