Black car maintenance

[camaro1969]

my camaro has been a project for the last few years, and i got it painted last year, i have been working on putting it back together, and was caught in a small rain shower while it was outside, so i put it back in the garage. Now i have small dried water drops all over the car, with dust on top.. how would i go about cleaning it.. would i just wash it with a new carwash mit and soap? should i wipe it off with a micro fiber cloth?

Thanks
