No. The reused water gets filtered, so its just water.
What kind of filtration are we talking about? My understanding is that apart from desalination (which is expensive) there is no other reasonable method. A standard water filter won't do it.
I think water re-use is only common in parts of the country where water is in short supply, which usually doesn't include places that get lots of snow.

Bingo. In my youth I worked for a pretty major car wash chain during summers etc. and worked in a number of states for them.
They stayed out of the water recycling mandated states.
I don't have a full list but most of the Midwest has no recycling.

That would be in California and Washington, and probably others, where salt is rarely used except on the mountain passes. It's not as much for water shortages here as it is to protect the Salmon and other stream fishes by putting less chemicals into the sewers and storm drains. Some cities here have banned washing your own car in your own driveway.

I'd like to think most places don't just let car washes dump untreated water into the sewer system or wherever else. But heck, maybe I'm optimistic about that. But in either case, you can minimize chemical run-off without re-using the water. You'd have to treat it either way.
There are Environmental Protection Agency regulations in place that require car washes to recycle or "reclaim" their water and treat it to remove all the dirt, oil, grime, sludge, salt and anything else. And in some places, city or county ordinances are in place to test that the car washes are doing their job.
