Yes, outside to get off the bugs and general dirt. I then come back with Stoner's rainproof. I'm also trying to test ReLoad if it would ever freakin rain.
When washing the car I will also wash the window with ONR. I find that ONR does a decent job if I dry the windows right away, but honestly you need a dedicated window cleaner like IPA, spray away or megs conc. glass cleaner.
