Question Creak from windshield after car wash?

I bought my car a couple months ago, and I've taken it to a local coin-op spray wash a few times since then. The place I go is right by the highway, so I always take a quick 5 minute highway run afterwards to dry the car. Each time I've gone, I've noticed a pronounced creaking sound from the lower windshield or dashboard area showing up right after the wash, and then fading slowly over the following days. Because it's affected by the wash, I'm assuming it has to be something on the outside of the car. It seems like it might be a result of the windshield seal rubbing against the glass when it's clean. Then, over the following days, as dust and oil builds up again, the sound diminishes (thought it never really goes away).

Anyone else have experience with something like this? Wondering whether there's an easy fix or whether I should trust a dealer to take a look.

In case anyone has the same problem(?), I've figured out that this sound is coming from the upper windshield seal. Unless someone knows of an easy DIY, I'll see if I can get my local dealer to replace or lubricate it.

There is a DIY on here named something like Replace Windshield Reveal Moulding.

BMW tech heard the noise today and agreed it was pretty loud. He's convinced it can't be the windshield seal though ("That glue just doesn't fail") and thinks it's coming from somewhere in the dash. I say that's impossible unless it's an area that water drains through, because the problem gets a lot worse when the car is washed. I really don't want them taking the dashboard apart unnecessarily, but oh well. Maybe I'll show him the posts here about that top seal degrading.
