Try to find a big rig truck wash near your location on Google maps. I cannot. Only 57 million car washes and no way to filter them out.

Edit: lo and behold: “big rig truck wash” is the magic phrase it turns out. “Truck wash”, “Semi truck wash”, “semi truck wash -car” don’t work but “big rig truck wash” does.

Fuck you Google, you waste my time.
