Splash Car Wash
1730 N 1st St, Hamilton, MT 59840-3111
Tip: most tunnels sell an unlimited monthly plan for $20–40 — it pays for itself at two washes a week. Early weekday mornings have no line; the queue peaks on sunny weekend afternoons and the first warm day after a snow week, when everyone rinses the road salt off at once.
