This is beyond what car washes do. They get ninety five percent of the dirt off the exterior. Keep in mind too that anything anyone did at these shops to cause your complaint, they have been doing to all the other cars they have worked on, and they would have had numerous complaints. They cannot survive financially if they have to stop working on one car to fix what they did to another car, so we need to look for something out-of-the-ordinary that was done to yours.
While trying to visualize this white stuff, the closest I can come is from watching my friend repairing cars in his body shop. Once a car is painted, he often has to "wet-sand" the body, then buff the paint. That leaves it real smooth, and the buffing leaves it very glossy and shiny. The water from the sanding sprays around and has to be washed off when it is still wet, otherwise the paint in it hardens on the windows. It takes a lot of scrubbing to get the dried stuff off. If it gets ignored, it comes off eventually from rain. I'm going through this right now. He specializes in rebuilding smashed one and two-year-old Dodge trucks. I bought a 2014 last year, and while it is not finished, I needed it a month ago. It had that sanding splatter on the left side. I hauled a trailer to an old car show swap meet where it rained on the way down and while we were packing up on the last day. By the time I got home, most of the splatter was gone. There is not much plastic on it, but what little there is around the wheels is covered in mud, so I do not know if the paint is gone from there. I am not at home right now to look at it. If he was delivering a vehicle to a customer, he would have washed that stuff off first, and with any plastic trim, he uses the hard bristle brush I mentioned. Usually he gets one of his daughters to do that while he works on other stuff. Cleaning that splatter only takes a couple of minutes.
While we are at it, allow me to share another tidbit I learned at the dealership. When you wash car windows, if you use a rag, you'll almost always get streaking that is hard to get rid of. Instead, use news print or brown paper towels, like you would find in a rest room. Those do not have the oils and chemicals in them that cause streaking. If you flip the paper over, do not allow any part of it to touch the glass that came in contact with your hands because fingerprint oil is just as bad. I tried that on a customer's car and the owner was amazed when I did that right in front of him. This works inside and outside, but you might have to do it twice inside if there is cigarette smoke on the glass. Any spray glass cleaner works.
Getting back to your problem, a better idea might be to visit the body shop at any new-car dealership. Let the manager look at it and offer a suggestion. We used to have trouble with smog affecting the paint on vehicles coming from Mexico. It got so bad that they were putting sticky protective sheets on the roofs and hoods while they were in transport. The detail people had to fix that before the vehicles were put out on the sales lot. They would have to fix what you have too, otherwise you can be sure they would hear about it from the salespeople.
