Do they operate the same format of car wash?
| Format | Blue Beacon | Cobblestone Car Wash |
|---|---|---|
| Truck / RV / Fleet | 32.7% | 0.4% |
| Full Service | 4.1% | 5.0% |
| Express Tunnel | 1.4% | 7.1% |
| Hand Wash | 3.7% | 0.9% |
| Detail Shop | 0.4% | 2.6% |
| Self-Serve Bay | 1.4% | 1.5% |
Format share is computed across customer review mentions, not over locations. A chain with mostly express-tunnel sites but heavy detail-shop talk in reviews will show both at non-trivial rates.
These two operate different formats — Blue Beacon runs Full Service, Cobblestone Car Wash runs Express Tunnel. That means they're serving different customer occasions (throughput vs. wash quality vs. price) rather than competing head-on.

In short: If customer-rating consistency is the deciding factor, Cobblestone Car Wash is the safer pick; if avoiding vehicle damage is the priority, Blue Beacon runs the lower reviewer-reported damage rate.
