Skylight Cleaning

Skylights are an excellent feature that brings natural light and a sense of openness to any space. To maintain their beauty and functionality, regular skylight cleaning is essential. Skylights are prone to accumulating dust, dirt, and debris over time, hindering the amount of light they can transmit. In this article, we will explore the importance of skylight cleaning, factors affecting skylight performance, cleaning frequency, tools and equipment needed, safe cleaning practices, maintenance tips, professional cleaning services, and how to keep your skylights in optimal condition for clear, bright views.

The Importance of Skylight Cleaning

Skylight cleaning is crucial to maintain the efficiency and visual appeal of these architectural features. Over time, skylights can accumulate dirt, dust, leaves, and other debris, reducing their ability to transmit natural light. Regular cleaning ensures that your skylights remain clear, maximizing the amount of sunlight that enters the space and enhancing the overall ambiance.

Factors Affecting Skylight Performance

Several factors can affect the performance of skylights:

  1. Dust and Debris: Dust, dirt, leaves, and other debris can accumulate on the skylight surface, obstructing the passage of light.
  2. Streaks and Stains: Watermarks, streaks, and stains from rain or condensation can reduce the clarity and transparency of the skylight.
  3. Moisture and Mold: Moisture can lead to mold growth on or around the skylight, affecting its appearance and potentially causing damage.

Cleaning Frequency for Skylights

The cleaning frequency for skylights depends on various factors, including the location, surrounding environment, and the type of skylight. Generally, it is recommended to clean skylights at least twice a year. However, if your skylights are exposed to high levels of dust, pollen, or pollution, more frequent cleaning may be necessary.

Tools and Equipment for Skylight Cleaning

To clean skylights effectively, gather the following tools and equipment:

  • Soft-bristle brush or microfiber cloth: Used for gentle scrubbing without scratching the skylight surface.
  • Mild cleaning solution: Create a solution by mixing mild dish soap or specialized skylight cleaner with water.
  • Squeegee or lint-free cloth: Used for drying and removing excess water from the skylight.
  • Extension pole: Helpful for reaching skylights that are higher or more difficult to access.

Safe Cleaning Practices for Skylights

Safety is paramount when cleaning skylights. Here are some important practices to follow:

  • Use a sturdy and stable ladder or scaffolding system when accessing the skylight.
  • Ensure the ladder or scaffolding is set up on a level surface and secured properly.
  • Use personal protective equipment (PPE), such as gloves and safety glasses, to protect against potential hazards.
  • Take caution when working at heights and be mindful of overhead electrical lines or other obstacles.

Cleaning Procedures for Skylights

Follow these step-by-step instructions to clean skylights effectively:

  1. Start by removing any loose debris, such as leaves or twigs, from the skylight surface using a soft-bristle brush or microfiber cloth.
  2. Prepare a cleaning solution by diluting mild dish soap or a specialized skylight cleaner with water.
  3. Dip the brush or cloth into the cleaning solution and gently scrub the skylight surface, paying extra attention to areas with stains or streaks.
  4. Rinse the skylight thoroughly with clean water to remove any soapy residue.
  5. Use a squeegee or lint-free cloth to dry the skylight, wiping away excess water and ensuring a streak-free finish.
  6. Inspect the skylight for any remaining spots or streaks and repeat the cleaning process if necessary.

Maintaining Skylights for Longevity

To keep your skylights in optimal condition, consider the following maintenance tips:

  • Trim nearby trees or foliage to prevent leaves and branches from accumulating on the skylight.
  • Regularly inspect the skylight for signs of damage, such as cracks or leaks, and address any issues promptly.
  • Clear gutters and downspouts to prevent water overflow that may reach the skylight and cause damage.
  • Remove any mold or mildew that forms on or around the skylight using appropriate cleaning solutions.

Professional Skylight Cleaning Services

For complex or hard-to-reach skylights, or if you prefer professional expertise, consider hiring skylight cleaning services. Professional cleaners have the experience, specialized equipment, and safety protocols to handle skylights efficiently and effectively. They can also perform thorough inspections, identify potential issues, and provide maintenance recommendations.


Regular skylight cleaning is essential for maintaining the visual appeal and functionality of these architectural features. By following safe cleaning practices, using the right tools and equipment, and considering professional services when necessary, you can ensure that your skylights remain clear, bright, and beautiful. With proper maintenance, your skylights will continue to bring natural light and a sense of openness to your space, enhancing its overall ambiance and enjoyment.
