Grab your can of clear silicone spray, available at auto parts or home depot, and spray it into the window run generously. Make sure you spray it all around the run, since you want to lubricate it completely.^{[3]

Question

Would WD-40 be fine?

WD40 is used mainly for freeing rusted bolts, and what little lube in it is oil based, which will attract dust. So, it's better to stick with the article's recommendation.

Question

What do I do if my window sticks to the top molding before it will go down? Should I lubricate the molding, and if so, what should I use?

Community Answer

You can use silicone to protect and lube the rubber seals around your car doors, which helps free up sticking glass. You might have to use Q-Tips to get in tight spaces.
