Aero goes out in all weathers, just hose it down before it goes back in Garage.
Aero Plus 8 goes out in all weathers. If there is salt about it gets a rinse, but if it is just grubby it goes back in the garage.
I wash the car occasionally, and more regularly use a waterless cleaner spray.
It is a car, and I don't know about others, but I get no pleasure from sitting in it in the garage going "vroom, vroom". So I go out and drive it.
