I have been kicking around the idea of Louvers on my rear quarter windows. I don't want the roush louvers ,but I liked how I could remove them to clean my windows. The other type of louvers are adhesive. And third type is SHR louvers that you remove the oem window , to install the new louver.
If I was to buy Ford Racing louvers. Is there a product out there to clean the glass spotless though the louver slots?
Or is the any adhesive brackets that a person can buy so I could screw the louver on to the glass like the Roush louver?

 

The side windows do not get dirty with the open louvers since they are designed as as extractor would. Besides, if the side windows would need cleaning a baby bottle brush does the job very easily.

 

I remember with my Roush rear quarter windows I would take them off in the spring so I could get the water spots off.
