Car Washes in Marathon, FL
2 car washes in and around Marathon, Florida — check the wash type before you drive over — touchless tunnels take trucks and lifted vehicles that soft-cloth tunnels turn away, and self-serve bays are the only option for roof racks and trailers.
Keys Car Wash
11055 Overseas Hwy, Marathon, FL 33050-3458
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.
