B & H Self-Services Car Wash in College Area runs a multi-bay self-service wash facility at 6916 El Cajon Boulevard, San Diego, 92115. The bays are equipped with high-pressure spray guns, foam brushes, spot-free rinse cycles, and a soap-and-wax program that runs through a timed-credit system. Post-body-shop vehicles needing a first wash after fresh paint or clear-coat application come through from the College Area collision network that includes International Auto Body & Collision on the same east-side corridor. El Cajon Boulevard at this block sits on the eastern edge of College Area near the La Mesa border, roughly three miles east of SDSU and directly on the 92115 ZIP line. The vacuum stations run high-suction commercial units positioned between the wash bays, pulling interior debris, pet hair, and floor-mat grit in the same visit as the exterior wash. A self-service car wash eliminates the markup of a full-service tunnel operation, and the timed-credit model lets customers control exactly how long they run each cycle — from a quick rinse to a full soap-brush-rinse-wax sequence. Auto repair shops along the El Cajon Blvd corridor, including Bob Brown's Automotive Services, route post-service customers here for a final exterior wash before vehicle pickup. The facility operates seven days a week with bay access from early morning through evening, covering the after-work wash window that most full-service car washes close before.
