I have a 2008 MB and the windows have become very difficult to slide back and forth. I have cleaned the slides and treated with silicone spray, but with little improvement. Does anyone have any advice on how to deal with these tight fitting windows? Thanks. Gale
I used an old toothbrush (dry) to scrub the tracks of any dirt, vacuumed them, then cleaned the rubber channels with a paper shop towel and white vinegar. After the tracks were dry, this dry lube product worked well:
