How to Clean Skylight Windows Inside and Out

Skylight windows are a fantastic way to bring natural light into your home, but they require regular maintenance to function effectively and look great.

This comprehensive guide will walk you through how to clean skylight windows, ensuring they continue to brighten your space for years to come.

Importance of Cleaning Skylight Windows

Skylights play a vital role in increasing natural light in our homes, but they’re often neglected when it comes to cleaning. Over time, dirt, tree sap, dust and debris, can accumulate on both the inside and outside of skylight windows. This buildup not only obstructs the amount of light entering your home but can also lead to long-term damage if left unattended.

Regular cleaning of skylights offers several benefits:

  1. Maximizes natural light entering your home
  2. Improves the overall appearance of your space
  3. Prevents potential damage to the skylight frame and seals
  4. Allows you to easily notice any signs of wear or leakage

Preparing for Skylight Window Cleaning

Before you begin the process of cleaning skylights, it’s essential to gather all necessary cleaning materials. Here’s what you’ll need:

  • Dish soap
  • A window cleaning pole or long-handled mop
  • A dry rag or microfiber cloth
  • A plastic tarp or sheet
  • Warm water
  • A bucket
  • A soapy sponge
  • A squeegee
  • A sturdy ladder (for cleaning a roof window)
  • A clean rag
  • White vinegar (for tough stains)
  • Glass cleaner (optional)

Safety should be your primary concern when cleaning a skylight, especially when working on roof windows. Place a plastic tarp beneath the skylight to protect your floor from drips and splashes (be careful that you or no one else steps on it, as it will be slippery).

If you’re cleaning a roof window, ensure you have a sturdy ladder for safe access.

Cleaning Skylight Windows: Inside Cleaning

Cleaning skylights from the inside is generally easier and safer. Here’s the step by step instructions on how to clean skylight windows from the interior:

  1. Start by removing any dust and debris using a dry mop or long-handled duster. This will prevent scratching the glass when you start washing.
  2. Mix a cleaning solution in your bucket using warm distilled water and a few drops of dish soap. Avoid using harsh chemical products that could damage the skylight frame or seals.
  3. Dip your soapy sponge into the cleaning solution and attach it to your window cleaning pole.
  4. Begin washing the skylight glass in a circular motion, being careful not to apply too much pressure. The circular motion helps to lift and remove dirt effectively.
  5. Once you’ve cleaned the entire surface, use a clean, damp rag attached to your pole to remove the soapy water.
  6. Finish by wiping the surface with a dry towel attached to the pole (if needed), to prevent water spots and streaks.

Cleaning Skylight Windows: Outside Cleaning

Cleaning skylights from the outside requires extra caution, especially when dealing with a roof window. If you’re not comfortable working on a roof, consider hiring a professional window cleaning company. If you decide to proceed, follow these steps:

  1. Safely position your sturdy ladder to access the roof window. Ensure it’s on stable ground and at the correct angle.
  2. Use the same soapy water solution as for inside cleaning.
  3. Gently wash the skylight glass using a soapy sponge attached to your window cleaning pole. Avoid using sharp or abrasive objects that could scratch the surface.
  4. Pay special attention to corners and edges where dirt, animal droppings and other debris tend to accumulate.
  5. Rinse thoroughly with clean water to remove all soap residue.
  6. Use a squeegee or dry rag to remove excess water and prevent streaking.
  7. Inspect the skylight for any signs of damage or wear while you’re up there.

Removing Tough Stains and Residue

Sometimes, regular cleaning with soapy water isn’t enough to remove tough stains or residue. Here’s how to tackle more stubborn dirt:

  1. Create a vinegar solution by mixing equal parts white vinegar and water.
  2. Apply this solution to tough stains using a clean rag.
  3. Allow it to air dry and sit for a few minutes before gently scrubbing with a non-abrasive sponge.
  4. Rinse thoroughly with clean water and dry the area to rid of vinegar residue.

For mineral deposits or extremely stubborn stains, you may need to use a commercial glass cleaner. Always test any new product on a small, inconspicuous area first to ensure it doesn’t damage the skylight.

Drying and Inspecting Skylight Windows

After cleaning your skylights, proper drying is necessary to achieve a streak-free finish and increased natural light in your home:

  1. Use a lint-free cloth or dry towel to thoroughly dry the skylight glass.
  2. Pay special attention to corners and edges where water can accumulate.
  3. Inspect the glass for any missed spots, streaks, or water spots.
  4. Check the skylight frame and seals for any signs of wear, damage, or water leakage.

Tips for Regular Maintenance

To keep your skylights clean and functioning optimally:

  • Perform a thorough cleaning of your skylights at least twice a year.
  • Consider occasional cleaning in between deep cleans to maintain maximum natural light.
  • Use a long-handled mop or duster to remove dirt, dust and spider webs between washings.
  • After stormy weather, check your skylights for any debris or damage.
  • If you have Velux skylights or other brands with specific cleaning instructions, be sure to follow the manufacturer’s guidelines.

Common Mistakes to Avoid

When cleaning skylights, avoid these common pitfalls:

  • Don’t use abrasive cleaning products or objects that could scratch the glass.
  • Avoid using a pressure washer, as it can damage seals and cause leaks.
  • Never stand directly on the skylight or apply excessive pressure while cleaning.
  • Don’t ignore signs of water leakage or damage – address these issues promptly.
  • Avoid cleaning skylights in direct sunlight, as this can cause cleaning solutions to dry too quickly and leave streaks.
  • Not putting down a plastic sheet or covering on your floor – this will stop the products that you apply to your skylight from potentially creating a mess in your home or damaging your floor.
