Weird white chalky powder deposit on inside of door glass seal

[not_elon_]

I just noticed this on all door windows. I have 8k mileage and have never cleaned the interior so this is some kind of build up over that duration. It reminds me of efflorescence on foundation walls.

I have the same and it leaves a lovely steak on the inside of the glass.

Clean my windows often enough I haven’t seen nothing like that. I have noticed a streak at the front of the drivers side window on the inside but I remove it with a microfiber when cleaning.

There is a lubricant inside the door panel that runs on the glass to keep it from squeaking. Horrible because what other car has that. I wash my car weekly and it’s still comes back. It’s been a year and No sign of it running out. lol. All windows

So is it a dry lubricant? Is yours white also?

That's the optional Hunter Biden Upgrade - it also comes with a firearm and crack pipe in the center console, and for the next 10 years you're pardoned from all speeding tickets. Solid upgrade - regretting not purchasing it...

It’s only building up on the inside. I wash the outside regularly.

I have the same issue on both windows. There's been a lot of road salt getting picked up and I'm wondering if it's leaking through the window seals. Both of my front windows have air leaking through that area.

Yes mine is white also but I do not see anything at the bottom of the window like yours and I can’t say if it’s chalky or not I just wipe it off.

The way it’s streaky I assume it’s moist not chalky.

I had a feeling it was something like that. Wonder if someone out there has a video or teardown of the door. I’d love to understand what it is.

We have had some mild winter with very little snow time for the truck and it happens on our ride. I don’t think it is anything kicking up inside the doors. Very little wet driving for us since May and it is still there.
