Keeping a multi-storey carpark clean is no easy task. There’s plenty of space to cover, all kinds of dust and debris to deal with, and no doubt a number of nooks and crannies to clean. Therefore, ensuring you as a building/business manager or owner are equipped with the right strategies is absolutely invaluable.

The right approach to cleaning is essential
At Sydney Sweep and Scrub, we specialise in cleaning large parking lots and garages with mechanical sweeping and scrubbing, pressure washing equipment, and whatever else is needed to get the job done. Through our experience, we’ve developed a deep understanding of the best practices to keep a multi-storey carpark in great shape.
Here are 15 of them!
Regular sweeping to remove debris and dust
Regular sweeping is essential to keep the parking garage clean and safe. By removing debris and dust on a consistent basis, we prevent dirt build-up that can lead to stains and unpleasant odours. This also helps with maintaining the condition of the concrete surface, ensuring the garage remains in good shape over time.
Pressure washing to eliminate stains and grime
Pressure washing is an effective way to blast away tough stains, dirt, and grime from concrete surfaces. It’s particularly important for high-traffic areas that accumulate oil, grease, and other contaminants. Our high-powered machines ensure that every corner is cleaned thoroughly, leaving your parking garage spotless and free from unsightly stains.
Scrubbing high-traffic areas for deep cleaning
High-traffic areas in parking garages are prone to dirt accumulation. Regular scrubbing of these areas ensures that any ingrained dirt, oil, or grease is removed. We use industrial-grade scrubbing equipment to restore the cleanliness and appearance of these surfaces, making your carpark look well-maintained and fresh.

Gum removal using specialised equipment
Gum stuck to parking garage surfaces can be both an eyesore and a slip hazard. Using specialised gum removal equipment, we effectively remove gum without damaging the concrete. This ensures the surfaces remain clean, smooth, and free from sticky residues that could cause accidents.
Oil and grease stain treatment with degreasers
Oil and grease stains are a common issue in parking garages. We treat these stains with powerful degreasers that break down the oil, ensuring the concrete stays clean and free from discolouration. Our expert team ensures that these stains are tackled effectively, helping maintain both the appearance and safety of your carpark.
Routine line marking to maintain parking space clarity
Maintaining clear and visible parking space lines is crucial for optimal car park organisation. Over time, these markings can fade due to traffic wear. We offer routine line marking services to refresh these lines and ensure that all parking spaces are clearly defined, making it easier for drivers to park efficiently and safely.
Cleaning entry/exit points to ensure smooth traffic flow
Keeping entry and exit points clean is essential to ensure smooth traffic flow within the parking garage. Regular cleaning of these areas helps eliminate obstructions like debris or spills that could cause delays or accidents, maintaining a clear path for vehicles to enter and exit efficiently.
Cleaning ventilation systems to ensure air quality
Good air quality is vital in parking garages, especially in multi-storey buildings. Regular cleaning of ventilation systems helps prevent the build-up of dust, pollutants, and odours, ensuring that air circulation remains optimal and the environment stays fresh and safe for all users.
Cleaning stairwells and elevators for overall hygiene
Stairwells and elevators are high-touch areas that require consistent cleaning, thanks to the large volume of people walking through these spaces. Ensuring that these areas are regularly cleaned helps reduce the spread of germs and bacteria, contributing to a hygienic environment for both pedestrians and those using the lift systems.
Window cleaning for visibility and aesthetics
Regular window cleaning is key to maintaining the aesthetics and functionality of a parking garage. Clean windows allow for better visibility, enhance natural light flow, and contribute to an overall more inviting and pleasant environment for users. If your facility has windows, it’s important to make sure they are not neglected!
Checking for drainage blockages and clearing debris
Blocked drainage systems can lead to water accumulating, flooding, and potential damage to the structure of your parking garage. Routine checks and clearing of debris from drainage systems help prevent flooding and maintain a dry and safe environment for vehicles and pedestrians alike. No one wants to park in a flooded facility!

Cleaning light fixtures for better visibility and safety
Clean lights are a must. They’re essential for maintaining visibility and safety within a parking garage, so dirty lighting fixtures are going to cause issues. Regular cleaning removes dirt and grime that can obstruct light, ensuring that the garage remains well-lit, reducing the risk of accidents and improving overall safety.
Maintaining signage to ensure legibility and safety
Clear and legible signage is critical in guiding drivers and pedestrians through the parking garage. Routine cleaning and maintenance of signage ensure that directional arrows, parking spaces, and safety instructions are always visible, helping maintain order and reducing confusion.
Removing moss or algae growth to prevent slip hazards
Moss or algae growth on surfaces can create slippery conditions, posing a serious slip hazard. Regular removal of this growth helps maintain a safe environment for all users by preventing accidents and ensuring the floors remain stable and secure. I think we can all agree that accumulated moss doesn’t really look great, either.
Deep cleaning after events to remove accumulated dirt
After events, parking garages often accumulate extra dirt and debris. Deep cleaning helps restore the space to its original condition by removing stains, litter, and accumulated grime, ensuring that the garage is fresh and ready for regular use once again. Make sure you stay on top of cleaning during or after an event.
