The worker's foot got stuck under a rail just before 1 p.m. at the Riverbend Hand Car Wash on 22290 E. La Palma Ave.
Orange County Fire Authority crews had to remove a portion of the car wash machinery to free the man.
It took about 30 minutes to remove the rail and extricate his foot. He was taken to a local hospital.
The extent of his injuries was not immediately disclosed.
It remains unclear how exactly he got his foot stuck inside the guide rail.
