Remove the hose nozzle and allow the water to "flow" over the dusty areas to "float" away the dust then "if you must" a moistened micro-fiber cloth to remove moisture. Put it inside so it doesn't water spot. No wax for at least a month or more, gotta cure / let the solvents breath out. Waxing fresh paint puts a seal coat and doesn't allow solvents to get out and can/will create solvent pops in the paint - yuk!!!! Definitely Drool city man, looks awesome. Congratulations.
