Anyone have any advice on how to clean the area where the rear deck shelf meets the rear window - roughly where the Lexus logo on the back window to the bottom of the rear deck shelf? The way they designed that interface between those two parts, it seems impossible to get a cloth or anything deep enough to wipe the film that formed there over the last 10 years. I have tried taking a cloth and pushing it in with a thin scraper, but it is so tight that you cannot get any pressure on the cloth to actually remove the film. I really don't want to remove the cover on the inside of the trunk to access that area, so hoping someone has found a trick I am overlooking. Any help appreciated.
