The final cut of TMC Podcast #29 is available now with topics time-stamped. We discussed the Tesla Cybertruck's expected 1 MW Ultra-Fast Charging capability, the Tesla Semi Delivery Event, the coming Model 3 refresh (project "Highland"), and more. You can watch it now on YouTube.
You can use Gummi Pflege or what I'd try to do first is just a water and a towel and give both your window edges and the rubber seals a good wipe. Do it all the way around the door and the door frame (both sets of seals).
Something else you can use to clean/protect is a bit of armor all - sprayed on a cloth then wiped (not sprayed direct onto the car/rubber). We've done this on our Camry and it works wonders. A VW golf needed something like Gummi Pflege and was super annoying haha.
