Express tunnel car washes have spread across the US, and every one of them is a small factory: conveyors, pumps, air compressors, hydraulics, reverse-osmosis water and controls. When something breaks, the wash makes no money, so chains pay for people who can fix it fast. A single-site tech starts around $21 an hour. Traveling and regional service techs make $65–100k, often with a company truck. One technician with welding school, a year on generators and Navy experience reports clearing $100k. Almost nobody grows up wanting this job, which is exactly why it pays.
