How Do You Clean Bubble Skylights?

Published in Skylight Maintenance 5 mins read

Cleaning bubble skylights effectively involves a gentle approach to preserve their acrylic or polycarbonate surfaces while removing dirt and grime to maximize natural light. The key is to use mild solutions and soft materials to avoid scratches.

Essential Steps for Cleaning Your Bubble Skylight

Maintaining the clarity of your bubble skylights is straightforward with the right tools and technique. Follow these steps for a sparkling, streak-free finish:

  1. Preparation and Safety First:

    • Gather Your Tools: Before you begin, assemble all necessary items like a sturdy ladder, buckets, soft cloths, and cleaning solutions.
    • Prioritize Safety: Always use a stable ladder and wear non-slip shoes when working on your roof. Consider having a spotter, especially if you're not comfortable working at heights. For detailed safety guidelines, refer to resources from organizations like OSHA.
    • Choose the Right Day: A cloudy, mild day is ideal, as direct sunlight can dry cleaning solutions too quickly, leading to streaks.
  2. Initial Rinse to Loosen Dirt:

    • Using a garden hose with a spray nozzle, wet the skylight thoroughly to loosen any surface dirt, leaves, or loose debris. This initial rinse helps prevent scratching during the scrubbing phase.
  3. Apply a Soapy Solution:

    • Mix a mild, non-abrasive soapy solution. A few drops of standard dish soap in a bucket of water work perfectly. For bubble skylights, it's crucial to use cleaners specifically designed for acrylic or plastic, or a very gentle household soap. Harsh chemicals or ammonia-based cleaners can damage the material over time.
    • Generously apply the soapy solution to the entire surface of the bubble skylight using a soft sponge or a clean, soft cloth.
  4. Gentle Scrubbing:

    • Scrub the skylight with a soft sponge, soft brush, or other gentle material, such as a microfiber cloth or a car wash mitt. Use light, circular motions to lift away dirt and grime. For stubborn spots, allow the solution to sit for a few minutes to penetrate the dirt before gently scrubbing again.
    • Avoid using abrasive pads, stiff brushes, or harsh chemicals like window cleaner containing ammonia or solvents, as these can scratch, cloud, or chemically damage the acrylic/polycarbonate surface.
  5. Thorough Rinsing:

    • Once you've scrubbed the entire surface, rinse the skylight thoroughly with clean water. Ensure all soap residue is completely washed away, as dried soap can leave streaks or attract new dirt.
  6. Drying for a Streak-Free Finish:

    • Allow the skylight to air dry, or for a completely streak-free finish, gently wipe it dry with a clean, lint-free microfiber cloth. A silicone squeegee can also be used, but ensure it's clean and free of grit to avoid scratching.

Addressing Specific Issues

Certain conditions can lead to unique challenges when cleaning skylights:

  • Tree Sap Residue: If trees overhang the roof, skylights may get sap residue stuck on the glass. For bubble skylights made of acrylic or polycarbonate, carefully use rubbing alcohol applied to a soft cloth, or a specialized acrylic cleaner. Always test in an inconspicuous area first. Avoid harsh solvents like paint thinner or acetone, as they will damage the plastic. For more details on caring for acrylic surfaces, consult guides like those from ePlastics.
  • Mold and Mildew: For stubborn mold or mildew, a diluted solution of white vinegar and water (1:1 ratio) can be effective. Apply, let it sit for a few minutes, then scrub gently and rinse well. For more severe cases, a very diluted bleach solution (1 part bleach to 10 parts water) can be used, followed by a thorough rinse.
  • Hard Water Spots: These can be unsightly. A solution of white vinegar and water (1:1 ratio) applied with a soft cloth and allowed to sit for a few minutes before rinsing can often dissolve mineral deposits.

Regular Maintenance Tips

  • Routine Cleaning: Clean your bubble skylights at least once or twice a year, or more frequently if you live in an area with a lot of dust, pollen, or trees.
  • Check Seals: While cleaning, inspect the seals around the skylight for any signs of cracking or degradation. Addressing these promptly can prevent leaks.
  • Trim Overhanging Branches: Prune any tree branches that hang directly over your skylights to reduce sap, leaf, and bird droppings.

By following these guidelines, you can ensure your bubble skylights remain clean, clear, and continue to bring natural light into your home for years to come.
