24-hour usually means the bays, not the staff. The office and detailing side keep business hours; the wash itself runs unattended. If the machine eats your payment at night, the refund happens in the morning.

Good to know

Are 24-hour car washes really open all night?

The self-serve bays and automatic tunnels usually are — they run unattended. Staffed services like detailing or hand-drying keep daytime hours even at locations advertised as 24/7.
