How do you keep the rubber lining the windows clean? I accumulate a lot of dirt in that area, especially in the back.

 

When you do a full detail, which should be every 3-4 months, use an old toothbrush or a horsehair detailing brush to give it a good scrubbing. To protect the rubber seals, use Einszett Gummipflege (http://www.nacarcare.com/1z-914805.html)

I use Griots Garage Vinyl & Rubber Dressing about once every four washes (about once a month). It's not cheap (nothing is at GG), but it's the best I've found for detailing rubber stripping. Also use this on tires & it doesn't attract/throw crud like silicone-based tire dressings.
