The title says it all, I use the Armor All cleaning wipes on the interior (hard plastics and what not) but they have been leaving some streaks on the lighter gray plastics, like those on the door that are around the lock/unlock, power window buttons. Nothing major though. And I use the Armor All leather wipes on the leather parts, not sure if this is a good idea or not or what other products are out there. And for windows the rain-x cleaning/water repellent spray on the outside, and a microfiber cloth which does a pretty good job of getting rid of the streaks on the windows, and windex on the inside. I am just curious what other items/brands you guys use, and how do you guys clean the window that is hard to reach by the rear brake light? I just shove the microfiber clothe under there and hope for the best...
