Patriot Car Wash
115 Long St, San Marcos, TX 78666-7039
Quick N Clean Car Wash
1644 Aquarena Springs Dr, San Marcos, TX 78666-7224
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.
