If you have a garage look into rinse-less car washes. I use Optimum No Rinse and it works great (although if you have a bunch of snow or slush on the car you would need to spray it off first at a do it yourself carwash). Last month it was 4° outside when I was washing my car.Guessing as long as I handwash almost every week then its okay haha... sucks for winter time... can't hand wash in the winter :/ I will freeze...and those automated machine washes are horrible they scratch vehicles so easily.
