I have friends that like clean cars and use touchless washes. Their paint looks ok, maybe like it could use a nice polish. The big difference I see is their trim looks terrible. Greyed plastic and dried out rubber.
Also I used to use a touchless in the winter to get the salt off the bottom of my truck. Like once a week. My truck underside looked worse than those that did nothing. A little research indicated that a large majority of car washes use recycled water for everything but the rinse. They have no equipment on site to remove that salt.
I`m lucky that we have warm days here and there in the winter, as long as it`s above freezing, I use ice fishing gloves and don`t mind doing a quick wash.
And even if none of the above was true, all the automated wash machines have lines at them whenever I want to use them. So it takes as long or longer to drive to one and wait than it does to just do a 30 minute wash at home.
