ASM Environmental, LLC provides professional parking garage cleaning in Pennsylvania, including industrial sweeping, mechanical floor scrubbing, and commercial pressure washing. Our experienced crews use specialized equipment to remove accumulated dirt, debris, and staining from multilevel commercial parking structures.

Here’s a behind-the-scenes look at how we did it.

Step 1: Removing Loose Dirt and Debris

Before introducing water or cleaning solutions, our team begins by removing loose dirt and debris throughout the parking structure.

Using commercial blowers, we clear accumulated material from behind curbs, along walls, around columns, and in corners where larger cleaning machines cannot reach.

Next, our PowerBoss Atlas industrial ride-on sweeper systematically cleans the parking decks, travel lanes, and ramps, collecting dirt, dust, and debris.

This preparation is essential. Removing loose material allows our degreasers and industrial floor scrubbers to work directly on the concrete surface, producing a more thorough and consistent cleaning result.

Step 2: Pretreating Oil Spots With Commercial Degreaser

Once the parking garage has been thoroughly swept, our team identifies oil spots, automotive fluid stains, and other heavily soiled areas requiring additional attention.

Before mechanical scrubbing begins, we pretreat these areas with a commercial degreaser specifically intended to break down oil and grease deposits.

Allowing the degreaser appropriate contact time helps loosen stubborn contamination so our industrial floor-scrubbing equipment can clean the affected surfaces more effectively.

This targeted approach is an important part of ASM Environmental’s cleaning process. Rather than treating every square foot of concrete exactly the same way, we address heavily contaminated areas before proceeding with the overall cleaning operation.

Step 3: Mechanically Scrubbing the Parking Deck

Following oil-spot pretreatment, our team begins mechanically scrubbing the parking deck using a Tennant M20 industrial rider sweeper-scrubber.

Unlike conventional sweeping, mechanical floor scrubbing uses rotating brushes and cleaning solution to agitate and loosen embedded dirt, traffic film, and other contaminants from the concrete surface.

For heavily soiled areas, ASM Environmental uses a double-scrubbing process. The initial pass allows additional scrubbing action and cleaning solution contact time, while the subsequent pass helps remove loosened contaminants.

This systematic approach allows us to clean large parking areas efficiently while giving heavily traveled and contaminated surfaces the additional attention they require.

While industrial sweeping and mechanical scrubbing are extremely effective on large parking surfaces, parking garages contain numerous areas that require additional attention.

Curbs, corners, walls, ramps, drains, parking stops, and other difficult-to-reach areas cannot always be thoroughly cleaned using ride-on equipment alone.

ASM Environmental uses commercial pressure-washing equipment to remove accumulated dirt, traffic residue, and stubborn surface contamination from these areas.

Our team carefully works along the edges of the parking structure, around obstacles, and across heavily soiled surfaces to provide a more complete cleaning.

The pressure-washing process also allows us to address remaining contamination following mechanical scrubbing, helping restore a cleaner, brighter appearance to the concrete.

By combining industrial equipment with detailed pressure washing, we can achieve results that would be difficult to accomplish using either method independently.

Step 5: Final Rinse and Inspection

Following mechanical scrubbing and pressure washing, our team performs a final rinse and inspection of the parking structure.

We carefully review the parking decks, travel lanes, ramps, curbs, drainage areas, and other surfaces to identify any locations requiring additional cleaning.

Our crews also document existing conditions observed during the project, including concrete cracking, previous repairs, deteriorated areas around drains, and locations where water may collect.

These observations can provide valuable information to facility management while helping distinguish routine cleaning needs from potential maintenance concerns.

Our goal is to leave each facility noticeably cleaner while providing the property management team with professional, documented results.

Step 6: The Results — A Cleaner, Brighter Parking Garage

The difference after a comprehensive parking garage cleaning can be remarkable.

Following our multi-step cleaning process, the concrete surfaces were noticeably brighter, accumulated dirt and traffic-related grime had been substantially reduced, and parking and traffic markings stood out more clearly against the cleaned surfaces.

From the parking decks and travel lanes to ramps, curbs, and detailed areas, the completed project demonstrates the value of combining specialized commercial cleaning equipment with an experienced crew.

For ASM Environmental, the finished result represents more than improved appearance. It reflects our commitment to thorough preparation, professional equipment, attention to detail, and consistent cleaning procedures.

The Finished Results: ASM Environmental’s comprehensive parking garage cleaning process leaves concrete parking decks, travel lanes, and ramps noticeably cleaner. Our combination of industrial sweeping, mechanical scrubbing, and commercial pressure washing delivers professional results for large commercial facilities.

Exterior Parking Garage Cleaning – Scranton, Pennsylvania

In addition to interior parking garage cleaning, ASM Environmental provides exterior building washing services for multistory parking structures.

At Geisinger Community Medical Center (GCMC) in Scranton, Pennsylvania, our team performed exterior façade cleaning using commercial pressure-washing equipment and an aerial boom lift to access elevated concrete surfaces.

Years of exposure to weather, airborne contaminants, and environmental staining can leave parking garage exteriors discolored. Our cleaning process addresses accumulated grime and staining, helping restore a cleaner, more professional appearance.

This project demonstrates ASM Environmental’s ability to handle both interior parking garage maintenance and specialized exterior cleaning at multi-story commercial facilities.
