Oceanside Self-Serve Car Wash offers several self-serve car washing stalls where customers can drive in and scrub down their vehicles. The stalls are well-sized, and there is even one for larger trucks and semis. The facility is cash-only and is open 24-hours per day, seven days per week. A drying station and vacuuming area are also on site. No appointment is necessary, and there is plenty of available parking if waiting is needed.
