I get the convenience of an auto car wash, just can't stand the damage. Even the "gentlest" one will eventually cause something you don't care for. Had a new place open up a few years ago and got a membership super cheap to wash the cruiser. Picked the works package that included a ceramic "wax" and all the other bells and whistles. Almost brand new black Explorer with almost flawless paint. 3 years later, it was swirled so bad that a local detailer couldn't get them all buffed out. And the trim was faded and tired looking. And fortunately the tires were fat, otherwise the tire guide rails would have scratched the wheels to pieces.
So for my personal cars, it's handwash only. Don't care about the cold, as long as it's above freezing, I'm washing. Just wear another pair of sweats. 2 bucket method, grit guards, separate wheel/tire cleaning tools etc. Wintertime they all get rinsed with Salt-Away underneath and all over including engine bay. Dried using a leaf blower to limit touching the finish. Takes me about 2-3 hours start to finish for a routine cleaning. I usually start really early, like 5AM early, so I'm done by around 8 and can get on with the day. I've done it this way for almost 50 years, and until I can't move anymore, will be the way I continue to do it. May not be the fastest, or most convenient, but makes me happy and thats all that counts.
