In the car wash, Max and 99 are getting soaked with suds. But they reach the drier area and in one shot you see the interior of the car sud-less. There is a cutaway and when they cut back the car is filled with suds!
If sound travels at 1,100 feet per second, and Control Headquarters is 10 miles from the car wash (52,800 feet, one mile is 5,280 feet), it would take the sonic boom 48 seconds to reach Control Headquarters. It took only a couple of seconds after the Kaos agent pushed the firing button.
