After I used a touchless car wash, the trim on my Model Y had oily-looking rainbow streaks dried on. I was able to remove it using the stainless steel appliance cleaner I use on my stove and refrigerator. I saw a lot of posts on forums about people trying to clean it with other chemicals, so I wanted to share the simple solution that worked for me.
Use at your own risk, though. This was just my experience, I can't guarantee it'll be safe for your car.
