Most likely plow dust.
Ever see a snow plow going down the road? Plowing snow, occasionaly hits an exposed portion of asphalt or concrete and the sparks fly. Sparks flew causing tiny particles of metal to be left behind all over the road. you drive over said particles which send them all over your vehicle. Mix with moisture and there you go!
Brake dust off of vehicles is far too small to become the deposits IMO. That's also why you typically only see it during winter months or shortly thereafter.
Clay bar will take it off, waxing, washing, scrubing generally won't.
Hydroflouric acid washes it off with no elbow grease, but I wouldn't try this unless you have some serious detailing experience!

I noticed this on the wife's Escape a few weeks ago. Since I was able to "pick" them off with my fingernail, I figured it was nothing to worry about. It was everywhere though, and I chalked it up to a harsh winter and picking things up off the road. Haven't noticed it on my Runner, but now I have to go take a closer look

As an alternative to claying to removing the rusting iron particles, you can use Carpro Iron X.
Iron X Iron Remover, CQuartz IronX, Paint Cleaner, paint decontamination
Way faster, easier, and more thorough then claying. Well worth the $20!

I may be telling you something you already know but these spots are not your car rusting, they are what are otherswise known as"fall out", where I come from. These are particles from local atmospheric fall out that rust once on your vehicle. They are only on the surface of your paint and are especially noticeable on white vehicles. I would use a clay bar and wax the vehicle once the spots are all gone. Have fun.

As mentioned- it's not rust. Go to Canadian Tire (or whatever you guys in Quebec have) and get either Meguiar's Smooth Surface Clay Kit, or the Mother's Clay Kit and clay bar your hood (or wherever these spots are most noticable). Make sure you use lots of quick detailer/clay lube and always re-work the clay to a clean piece as it gets dirty to avoid scratches. Re-examine the area. If everything looks good/better, apply a coat of wax to the area you clayed. I personally use Meguiar's Ultimate Liquid Wax- I'm sure some on here may disagree and there may be a better product but Meguiar's overall has a pretty good reputation IMO.
I definitely would recommend Iron X to remove rail dust!
I spent many hours researching on detailing forums and discovered that this stuff came highly recommended by detailers. If preferred, you can clay bar as the next step though pictures on these sites show very little contaminants on the clay bar after use of Iron X.
We used it on our (white) Lexus that was riddled with rail dust as well as the 4Runner. It absolutely works like a charm! This stuff can also be sprayed on your wheels but try to avoid spraying your wheel weights as Iron X may discolour them.
Just a warning that it smells extremely horrible though lol!

Not that the average person could get Hydrofluoric Acid (HF), but I think you meant Hydrochloric (HCl). HF is some really nasty and strong acid that if you get on you, you will never forget it. It targets the calcium in your body has to be neutralized by using Calcium Gluconate gel.
My suggestion would be to clay bar and see if that works before using any chemicals (especially strong acids or bases). I have used dilute acidic acid (vinegar) to remove water stains with good results but I did not leave it on long and washed it thoroughly very quickly to make sure I did not damage the clear coat. If you have any doubt, take it to a detailer and have them look at it. There are a lot of tricks to that trade. Good Luck

I had these spots on my doors and liftgate, I attributed mine to the winter and mag chloride and whatever else on the roads. I did a good wash then used a clay bar on it, about 90% came off without a problem. I figured I would do it all again in a couple months when we finally dry out in Colorado.
Before I used the clay bar I just tried to rub it off when washing with zero success.

Now the real question, does it harm paint or plastics?

Would that work on windows?

Yes, a little vinegar and water will help remove water spots from glass. It dissolves the hard water deposits rather well.
Good question..I too wondered the same thing. This stuff is safe on paint and plastic.
