Let me state for the record that I DO enjoy the fact I have a folding rear window like the classic roadsters of days gone by. The day I start whining about wanting a defrosted glass rear window, seating for four, and more storage space — please sentence me into a LeBaron for 30 days. Even so, after reading Robert’s eye-opening article on Meguiar’s plastic window product, I figured I should recommission the one I bought months ago and shelved away.
I’ve never really done too much to clean mine since delivery back in September ’96. Upon recommendation from the dealer, I remember once trying Pledge spray on it. That didn’t work well. It just resulted in me having to exert lots of work getting rid of oily residue off the surface. I HAVE taken care of the window by using the supplied Rear Window Blanket #82-11-1-469-778, but two years will build a hazing no matter what precautions are taken. This hazing or fogging is caused by microscratches on the surface. The bad practice of using a glass cleaner might rid the surface of dirt and waterspots, but thanks to FredK’s excellent explanation, you’ll know better to stay away from it…besides, it doesn’t remove the microscratches.
Robert used the heavy-duty regimen of Meguiar’s #17 Cleaner followed by Meguiar’s #10 Polish. I used a slightly different product, Meguiar’s #18 Cleaner/Polish. I suspect most who’ve cared for their rear window as I have will only need to use this all-in-one product. The steps are quite simple — spray on, wipe with cloth, and use a drier side to buff clean.
I elected to use smooth cotton polishing cloths. They were the consistency of a thick cotton t-shirt (which would probably work just as well). One cloth was used to spread the sprayed liquid, another cloth was used to polish dry the area. I worked in small sections at a time and only used straight back and forth motions… not circular! Both inside and outside of the window was cleaned this way. The passenger’s half was done first to show how dramatic the difference was.
Use newspaper or a beach towel to line the rear console plastic as errant spray droplets will be bothersome to buff clean. Once you’re finished, the plastic window will look just as clear as the day it rolled off the assembly line! The bottle was hardly used and I suspect the window will only require no more than three cleanings a year.
