Picayune issue after detailing Macan 4

[SteveY]

I have had my Macan 4 about 10 months and have washed / detailed it several times. Cleanup is perfect except for one issue: the rubber strips on both sides of the windshield turn up with very visible white spots after washing (see pic). This is the only part of the car that spots like this. Bumper cleaner removes to spots.

Has anyone else experienced this? Wondering if it a defect in the material used for the molding.

I get that too. It’s not very visible so I haven’t tried to deal with it.

In the past (back in the UK) I kept a bottle of BMW Gummi-Pflege in my detailing bag for keeping on top of the rubber trim. I haven't sourced any over here yet. It worked a treat at getting the rubber clean and keeping it flexible. Here we go: https://www.getbmwparts.com/oem-parts/bmw-bmw-gummi-pflege-rubber-care-83192449390. I'm sure other products are available, but the hardcore detailing nuts I ran with back then (!) swore by it and I wasn't disappointed.

EDIT: I realise it may not solve your exact problem but I was so delighted I could remember the excellent name of the product that I had to post it

I have a Gummi Pflege bottle somewhere that I used to stop squeaking from door seals rubbing against paint on another car. I will see if that helps with the discoloration.

I have the same issue with my Turbo. I use this stuff every third wash or so, and the spots are completely gone, soft water in the NE USA.

And if you’re looking for Gummi Pflege, it is available on Amazon.

wouldn't this mean you guys aren't drying the car after washing?

I use a microfiber drying towel to take care of any water left on the car after the air dryer of the touchless car wash is done.

Just noticed this on my car today while passing time during charging. It seems to show up worse under certain lighting conditions and angles. I am pretty sure it wasn’t like this just a few days ago. Car was sitting in the sun for several hours today. Wondering if maybe it’s caused by the material drying out in heat or sunlight.
