How to Clean a Parking Garage

Parking garages are large, exposed concrete structures that collect everything: dirt, oil drips, road grime, litter and leaves. A clean garage is safer, lasts longer and reflects well on the property. Cleaning one efficiently takes the right approach for big concrete areas.

Start With Debris Removal

Garages accumulate litter, leaves and dirt across large decks. Removing this dry debris is the first step, before any wet cleaning. For big areas, mechanized sweeping or a powerful vacuum system covers far more ground than hand sweeping and keeps dust down.

Scrubbing the Deck

Concrete decks get a film of oil, exhaust residue and grime that sweeping does not remove. A large auto scrubber, ideally a ride on for big garages, scrubs the deck and recovers the dirty water. This is far more effective than hosing, which just spreads the grime and creates runoff issues.

Oil Stains and Spills

• Treat fresh oil spills with absorbent, then scrub with a degreaser
• Work set-in oil stains with a degreaser, dwell time and a floor machine with a scrub brush
• Recover the slurry rather than letting it dry back onto the concrete
• Address spills promptly before they spread under tires

Stairwells and High Touch Areas

1. Clean and deodorize stairwells, which often collect odor and litter
2. Disinfect elevator buttons, handrails and payment kiosks
3. Pressure clean or scrub entry and exit lanes where grime concentrates
4. Keep drains clear so water does not pool

Safety and Scheduling

Garages operate around the clock, so cleaning works section by section with proper signage to keep vehicles and people safe. Wet floors and equipment need clear marking. Large, efficient machines let a crew cover a big structure in a reasonable window. Equip the work with our auto scrubbers and floor machines.
