Commercial Parking Garage Power Washing in St. Louis, MO

This project involved a full parking garage cleaning in Downtown St. Louis, MO. This garage was across the street from the Dome at The Americas Center and Stifel building, staple land marks in the downtown area. The structure spanned six floors and required a combination of water sweeping and pressure washing to remove the build up that naturally accumulates in high-traffic urban garages. Our team on site was the power washing experts at Exterior Cleaning Solutions STL, and they handled every phase of the job.

We began each level with a thorough water sweeping to remove loose debris such as leaves, trash, and grit that can hide under vehicles or gather at drains. Sweeping first makes the pressure washing more effective because it exposes the surfaces that need the most cleaning and prevents large debris from clogging our equipment.

After sweeping, each floor was pressure washed using industry-grade equipment suited for a parking garage environment. The pressure washing targeted oil stains, general dirt, and bird droppings on driving lanes and parking stalls. Technicians worked methodically, rinsing surface contaminants away and repeating passes where buildup was heavier. Because the garage covered multiple levels, our team followed a consistent sequence to keep runoff and drainage controlled while maintaining safety for vehicles and pedestrians.

Rinsing was an important final step. The team rinsed away loosened dirt, bird droppings, and remaining debris, leaving the concrete surfaces cleaner and clearer. Rinse cycles also help prevent streaking and reduce the chance that residue will redeposit in corners or along curbs. For this project, Exterior Cleaning Solutions STL focused on uniform results across all six floors so each level matched the next in appearance.

Working in Downtown St. Louis, MO requires attention to scheduling and access, and the crew coordinated to minimize disruption to garage users while completing the cleaning efficiently. The combination of sweeping and pressure washing is a common and effective approach for garage maintenance, and it was applied here to address the typical urban contaminants found in parking structures.
