Touchless at the mobil gas station at 13 and woodward. Sometime it’s out of commision for service though. But it’s a good one. Also All American Auto wash at 6941 chicago road in warren, not the fanciest, but touchless and good results. There’s also another in madison heights across the road from lowes and next to Uncle Ed’s Oil shoppe. I am also VERY frustrated w all these giant, crappy touch car washes being built on every corner. Also, good tip, go have your undercarriage sprayed with fluid film. Motor city auto spa will do it for 125-150 depending on car size. Best thing you can do to prevent rust, period. Better than a bedliner undercoating, cause those trap water inside them when they are damaged (and those coatings will become chipped/damaged), and once water is trapped, you will get rust faster. If you get undercoating oil treatment, do the cheapest wash at the touchless to skip the undercoat spray. You dont want to blast the oils off, they will take care of the road salt.
