  • Environmental impact: Cleaning techniques can consume large amounts of water and generate waste, so it’s essential to consider the environmental impact of your maintenance practices.

Understanding Different Types of Parking Lot Surfaces

Before diving into cleaning techniques, it’s essential to understand the different types of parking lot surfaces commonly found in Canada. The most prevalent materials used for parking lots are asphalt, concrete, and paver stones. Each material has its unique characteristics and cleaning requirements, so it’s crucial to tailor your cleaning approach accordingly.


Asphalt is a popular choice for parking lots in Canada because it’s cost-effective, durable, and flexible. Asphalt surfaces can withstand

freezing and thawing cycles, making them well-suited for the Canadian climate. However, asphalt is susceptible to damage from oil, gasoline, and other chemicals, which can lead to staining and deterioration. Regular cleaning is essential to prevent these issues and prolong the life of the asphalt surface.


Concrete is another common material for parking lots in Canada. It’s strong, durable, and requires less maintenance than asphalt. However, concrete can still be prone to staining from oil, grease, and other substances. Additionally, the freeze-thaw cycles in Canada can cause concrete to crack and deteriorate over time. To maintain a pristine concrete parking lot, regular cleaning and sealing are necessary.

Paver stones

Paver stones are a visually appealing option for parking lots, as they come in various shapes, sizes, and colors. They’re also durable and can be easily replaced if damaged. However, paver stones require regular maintenance to prevent weed growth and shifting, which can create an uneven surface. Cleaning and sealing paver stones can help maintain their appearance and stability.

Key takeaways:

  • Asphalt, concrete, and paver stones are the most common types of parking lot surfaces in Canada.
  • Each material has unique characteristics and cleaning requirements, so it’s crucial to tailor your cleaning approach accordingly.
  • Regular cleaning and maintenance can help prolong the life of your parking lot surface and maintain its appearance.

Technique 1: Sweeping and Vacuuming

Sweeping and vacuuming are essential techniques for keeping your parking lot free of dirt, debris, and trash. There are several methods for sweeping, including manual, mechanical, and vacuum sweeping. Each method has its benefits and drawbacks, so it’s important to choose the right approach for your parking lot’s needs.

Manual sweeping

Manual sweeping involves using brooms and dustpans to clean the parking lot by hand. This method is cost-effective and suitable for smaller areas. However, manual sweeping can be labor-intensive and time-consuming, making it less practical for larger parking lots.

Mechanical sweeping

Mechanical sweeping uses specialized equipment, such as street sweepers or ride-on sweepers, to clean the parking lot more efficiently than manual sweeping. Mechanical sweepers are suitable for larger parking lots and can effectively remove dirt, debris, and trash. However, they can be more expensive than manual sweeping methods and may require specialized training to operate.

Vacuum sweeping

Vacuum sweeping is a type of mechanical sweeping that uses powerful vacuums to remove dirt and debris from the parking lot surface. This method is highly effective at collecting fine dust and particles that other sweeping methods might miss. Vacuum sweepers can be more expensive than other types of sweepers, but they provide a thorough cleaning that can improve the appearance and longevity of your parking lot.

Key takeaways:

  • Sweeping and vacuuming are essential for maintaining a clean and debris-free parking lot.
  • Manual, mechanical, and vacuum sweeping methods are available to suit different parking lot sizes and cleaning needs.
  • Choose the right sweeping method based on your budget, parking lot size, and desired level of cleanliness.

Technique 2: Pressure Washing

Pressure washing is a powerful cleaning technique that uses high-pressure water spray to remove dirt, grime, and stains from surfaces. This method is particularly effective for cleaning parking lots, as it can quickly and efficiently eliminate built-up debris, grease, and oil stains. In this section, we’ll cover the basics of pressure washing, its benefits, and environmental considerations.

Pressure washing basics

Pressure washing equipment consists of a high-pressure pump, a hose, and a spray gun with various nozzle attachments. The pressure washer pump generates a powerful water stream, which is directed onto the surface to be cleaned through the spray gun. By selecting the appropriate nozzle, you can control the water pressure, spray pattern, and cleaning intensity.

Pressure washing can be done using cold or hot water, depending on the type of debris and stains being removed. Hot water pressure washing is more effective at dissolving grease and oil stains, while cold water is suitable for general cleaning tasks.

Benefits of pressure washing

Some of the key advantages of pressure washing for parking lot cleaning include:

  • Fast and efficient cleaning: Pressure washing can cover large areas quickly, making it an ideal solution for parking lot maintenance.
  • Effective stain removal: The high-pressure water spray can remove even the most stubborn stains, such as oil, grease, and tire marks.
  • Reduced need for chemicals: Pressure washing often eliminates the need for harsh cleaning chemicals, as the high-pressure water is sufficient to remove dirt and stains.

Environmental considerations

Although pressure washing is an effective cleaning technique, it’s essential to consider its environmental impact. High water consumption and runoff containing pollutants can harm the environment. To minimize the environmental impact of pressure washing, consider the following:

  • Use eco-friendly cleaning agents: Choose biodegradable and environmentally friendly cleaning products when necessary.
  • Recycle water: Invest in a water recovery system that collects and filters used water for reuse.
  • Proper waste disposal: Dispose of wastewater according to local regulations to prevent pollution.

Key takeaways:

  • Pressure washing is a powerful cleaning technique for maintaining parking lots, offering fast and efficient cleaning and effective stain removal.
  • Environmental considerations include using eco-friendly cleaning agents, recycling water, and proper waste disposal.
  • Always follow local regulations and guidelines to minimize the environmental impact of pressure washing.

Technique 3: Scrubbing

Scrubbing is another effective cleaning technique for parking lots, particularly for removing stubborn dirt, grime, and stains. Scrubbing machines use rotating brushes and cleaning solutions to clean surfaces, making them ideal for tackling heavily soiled areas. In this section, we’ll discuss the types of scrubbing machines, when to use scrubbing, and how to choose the right scrubber for your parking lot.

Types of scrubbing machines

There are two main types of scrubbing machines: walk-behind scrubbers and ride-on scrubbers. Both types use rotating brushes and cleaning solutions to clean surfaces. Walk-behind scrubbers are smaller, more affordable, and suitable for tight spaces. Ride-on scrubbers are larger, more powerful, and ideal for cleaning expansive parking lots more efficiently.

When to use scrubbing

Scrubbing is most effective for removing heavy dirt, grime, and stains that cannot be eliminated with sweeping or pressure washing alone. Some situations where scrubbing is particularly useful include:

  • After construction or renovation projects: Scrubbing can remove dirt, dust, and debris left behind by construction work.
  • For heavily soiled areas: Scrubbing can tackle stubborn stains and accumulated grime, restoring the appearance of your parking lot.
  • In combination with other cleaning techniques: Scrubbing can be used alongside sweeping or pressure washing to achieve a thorough

Choosing the right scrubber 

Selecting the right scrubber for your parking lot cleaning needs depends on several factors, including the size of your parking lot, the types of stains you’re dealing with, and your budget. Consider the following when choosing a scrubber:

  • Size of the parking lot: Larger parking lots may require ride-on scrubbers for efficient cleaning, while smaller lots or tight spaces may be better suited for walk-behind scrubbers.
  • Cleaning requirements: Evaluate the types of stains and the level of dirt in your parking lot to determine the scrubber’s necessary cleaning power and features.
  • Budget: Scrubbing machines vary in price, so consider your budget when selecting the right equipment.

Technique 4: Spot Cleaning and Stain Removal

  • Identify common stains and choose appropriate cleaning solutions for effective removal.
  • Employ a combination of pressure washing, scrubbing, and chemical treatments to tackle various stains.

Seasonal maintenance is essential for keeping your parking lot clean and safe throughout the year. In this section, we’ll cover preparing for winter, snow removal, and spring cleaning tips for your parking lot.

Preparing for winter

Winter weather can wreak havoc on your parking lot, leading to snow and ice accumulation, potholes, and salt damage. To prepare your parking lot for winter, consider the following:

  • Repair cracks and potholes: Address any existing damage to your parking lot surface to prevent further deterioration caused by freezing and thawing.
  • Apply a sealant: Seal your parking lot surface to protect it from snow, ice, and salt damage.
  • Clear storm drains: Ensure that storm drains are free of debris to prevent flooding and ice buildup.

  • Inspect for damage: Check your parking lot for any cracks, potholes, or other damage caused by freezing and thawing, and schedule necessary repairs.
  • Remove leftover sand and salt: Sweep and pressure wash your parking lot to remove any remaining sand, salt, and debris from winter maintenance.
  • Clean storm drains: Clear out any debris from storm drains to prevent flooding and ensure proper drainage during spring rains.
