Concrete Dust on Car ... HELP!
Hopefully no one has had this happen to them...but,
The apartment that I live in had a contractor come with his concrete saw to cut up the sidewalk outside. Apparently he opened up my garage door while cutting and now my entire 2 month-old 911 is covered in concrete dust. Had anyone experienced this before and if so, what's the best way to remove it? It seems like you could easily mess us the paint by just washing it or hosing it down without the proper tools, etc.
Any advice the community has with something like this would be great.

I would get a high pressure rinse on it. That should take care of it.

Do you have any layer of protection the paint (wax)?
Your best bet is to blow everything off with compressed air first, then have a go at it with a high pressure wash. Don't touch the paint at all.
If the dust is still in there, I'd personally go for clay or take it to a GOOD detailer.

It has Cquartz fienst reserve and a PPF film on the front end.
Thanks for the advice - I don't have all the tools here to do it myself, so will likely need to take it to a detailer.

My $.02:
The dust is abrasive. I would try to remove as much as possible in any combination of methods that do not involve a force applied that will push it against the paint. Anything from compressed air to rubbing a clay bar on it would result in friction. I'd use the very low-pressure soap spray from a pressure washer with a good car soap that lifts dirt off the paint and let it work in the shade for a few minutes. If you don't have one, just mix the soap in a bucket and slowly pour it on all areas of the car. Then, using a regular hose to rinse, let the water run softly from the top down. I'd do this at least three times, the last time rinsing with more pressure. Only after you removed as much as is possible without touching it, I'd spray the soap once again and fill a bucket with soapy water. SOFTLY run a mitt over the whole car, going over each area only once and dipping and cleaning the mitt for every 2 square feet, not stirring the mix in the bucket and only using the liquid in the top portion, letting the heavier grit fall in the bucket. Rinse the car again, dump the soapy water. Wash the bucket and mitt, repeat. That should do it.

Wash the car.....use a foam soap sprayer or bucket with lots of suds....first put a high pressure sprayer with the larger fanned out attachment on it...easy peasy...nothing to freak about

At least dust from sawing concrete should be less chemically active (and dangerous) than cement dust before it reacts with water. I agree that the biggest risk is abrasion, especially since concrete contains sand and gravel and will generate dust like sandpaper.

This is concrete dust, not cement, way different, this is just very gritty dust to deal with, without touching it.
OP possibly doesn't doesn't have touchless/rinseless wash or a pressure washer. A gentle hose off for the the worst, spray a regular car wash / water mix with a spray bottle, in complete excess, rinse it off again and take a look at what you have.
my 2c anyway

Anytime I end up with something abrasive on the paint, I visit a coin-operated car wash and blow the stuff off with plenty of water. Then home and a regular wash after soaking the whole car with plenty of soapy water just in case. I've never had a problem with this method...
