How to Clean Skylights Safely: A Step-by-Step Guide
Cleaning skylights can be risky, but with the right tools and methods, you can do it safely and effectively. Here’s a quick summary to get you started:
- Safety First: Always use non-slip shoes, stable ladders, or extension tools. For outdoor cleaning, consider a safety harness if climbing is required.
- Tools You’ll Need: Telescoping poles, soft microfiber cloths, mild soap or vinegar solutions, and distilled water for streak-free results.
- Indoor Cleaning Tips: Use extension tools to remove dust and debris. Clean with mild solutions and dry properly to avoid streaks.
- Outdoor Cleaning Tips: Spray with water to loosen dirt, apply a gentle cleaner, and rinse with distilled water. Avoid high-pressure washers or abrasive materials.
- Maintenance Schedule: Clean skylights twice a year, inspect for damage regularly, and clear debris monthly to prevent buildup.
If heights or tools are a concern, hiring a professional is a safer option. Regular care keeps skylights clear, reduces energy costs, and prevents long-term damage.
The Essential Guide to EASY Skylight Maintenance
Safety and Setup Requirements
Before cleaning your skylights, preparation is essential to ensure both safety and efficiency. Start by evaluating your skylights to determine the safest cleaning approach.
Check Skylight Access Points
Take note of your skylights' location and the surrounding roof structure. Measure the height to decide on the safest access method. For most homes, cleaning from the inside is generally safer. If you need to clean the exterior, evaluate whether you can safely reach the skylight using an extension tool from the ground.
Required Safety Equipment
For interior cleaning, you'll need:
- A sturdy platform or step ladder with non-slip feet
- Closed-toe, non-slip shoes
For exterior cleaning, ensure you have:
| Equipment Type | Specific Requirement |
|---|---|
| Fall Protection | OSHA-approved safety harness with secure anchor points |
| Support Equipment | Commercial-grade scaffolding or a weight-rated extension ladder |
| Footwear | Non-slip work boots with strong traction |
If you're unsure about cleaning the exterior or don't have the right safety gear, hiring a professional is a safer option.
Cleaning Tools and Materials
Here’s what you’ll need:
- Extension Tools: Telescoping poles with adjustable heads
- Cleaning Solutions: Mild dish soap or a white vinegar mix (avoid ammonia-based products)
- Cleaning Materials: Soft microfiber cloths, non-abrasive sponges, and absorbent towels
- Protection: Plastic tarps to catch drips
- Water Source: A bucket for indoor cleaning or a garden hose for outdoor cleaning
Tip: If you live in an area with hard water, use distilled water to prevent mineral deposits. Always check your skylight's material before choosing a cleaner, as some solutions can damage acrylic or protective films.
Once you’ve gathered your safety gear and tools, you’re ready to start cleaning your skylights from the inside.
Cleaning Skylights from Inside
Remove Dust and Debris
Spread a plastic tarp under the skylight to catch any falling debris. Use an extension rod fitted with a microfiber cloth to clear away cobwebs and dust. Make sure to stand on a stable surface, like an exercise step, for safety.
Tip: A microfiber duster with an adjustable pole works great for removing dust without scratching the skylight.
Clean with Solutions
Prepare a cleaning solution using one of these options:
| Solution Type | Mixture Ratio | Best For |
|---|---|---|
| Mild Soap | 1 tablespoon per gallon of water | General cleaning |
| White Vinegar | 1:1 with distilled water | Removing mineral deposits |
| Plain Distilled Water | 100% distilled water | Hard water areas |
Apply the solution with a soft, lint-free cloth or a non-abrasive sponge attached to your extension rod. Clean small sections at a time, starting in one corner and working methodically. For tougher grime, pre-wet the area before scrubbing. Avoid ammonia or alcohol-based cleaners, as these can harm acrylic skylights or protective coatings.
Prevent Streaks While Drying
Wipe in a side-to-side motion, then follow with top-to-bottom strokes. Check the skylight from different angles to spot streaks. If necessary, rinse with distilled water before drying. Dry during cooler parts of the day to prevent quick evaporation. Keep your drying cloths clean, and switch them out when they get damp to avoid water marks. When using extension tools, apply steady pressure for consistent results.

Cleaning Skylights from Outside
Using Extension Tools
Extension tools are a safe and effective way to clean skylights from the ground. Telescoping brushes and squeegees allow you to reach the surface without the need for climbing.
If accessing the roof is unavoidable, make sure to use these safety essentials:
| Equipment | Purpose |
|---|---|
| Safety Harness | Secures you to a roof anchor point |
| Sturdy Ladder | Provides stable access to the roof |
Once you're set up, tackle any tough grime with appropriate cleaning solutions.
Removing Stubborn Dirt and Stains
Start by spraying the skylight with a garden hose to loosen dirt and debris. Then, apply a gentle cleaning solution for tougher stains:
- Mix 1 tablespoon of dish soap with 1 gallon of warm water for general cleaning.
- For mineral deposits, combine white vinegar and distilled water in a 1:2 ratio.
- Use a soft sponge attached to an extension pole to apply the solution.
Note: Avoid abrasive materials or high-pressure washers, as they can harm the skylight's surface and seals.
Final Rinse and Dry
Rinse the skylight thoroughly with clean water to remove all soap. For best results:
- Use distilled water for the last rinse to avoid mineral spots.
- Rinse from top to bottom, then dry with side-to-side and vertical strokes.
- Clean during cooler parts of the day to prevent streaks caused by rapid evaporation.
Regular Skylight Care
Cleaning Schedule
Plan to deep clean your skylights during spring and fall. Here's a suggested maintenance timeline:
| Task | Frequency | Purpose |
|---|---|---|
| Visual Inspection | Weekly | Check for leaks or damage |
| Debris Removal | Monthly | Clear away leaves and debris |
| Deep Cleaning | Twice Yearly | Remove built-up dirt and grime |
| Professional Inspection | Annually | Evaluate condition and integrity |
Spotting Issues Early
During each cleaning, take a moment to inspect your skylights for potential problems. Pay attention to:
- The condition of seals to ensure they’re intact
- Cracks or scratches on the glass
- Condensation between panes
- The security of the flashing around the skylight
"Your skylights should be thoroughly cleaned once or twice per year. After this amount of time, they'll have gathered a lot of dirt, dust, and spiderwebs that you'll want to get rid of."
Catching issues early can help you avoid costly repairs down the road.
Cutting Down on Dirt Buildup
Modern skylights often come with coatings that make maintenance easier. To keep dirt buildup to a minimum:
- Remove leaves and debris from nearby areas
- Trim any overhanging branches
- Schedule professional cleanings every 2–3 years
- Ensure drainage channels remain clear
For example, VELUX’s Neat glass technology uses silicon dioxide and titanium dioxide to break down organic materials and prevent water spots when exposed to UV light. This treatment helps maintain clear views while reducing the need for frequent cleaning.
Taking care of your skylights consistently can help them last longer and stay in great shape.
Summary and Next Steps
Cleaning skylights requires careful attention to safety and proper techniques. For indoor cleaning, stick to non-abrasive solutions, use a stable ladder, extension tools, and ensure the area is well-lit.
Outdoor cleaning poses more challenges and risks. As Glass Doctor explains:
"Skylight cleaning can be particularly dangerous because it requires you to gaze upward as you work, impairing your balance."
Before deciding whether to tackle the job yourself or hire a professional, consider these factors:
| Factor | DIY Cleaning | Professional Service |
|---|---|---|
| Height | Safe for ground-level work | Handles any height |
| Equipment | Basic cleaning tools | Specialized safety equipment |
| Inspection | Limited visual check | Thorough evaluation of seals |
| Risk Level | High for exterior cleaning | Low, managed by trained experts |
If you're concerned about heights or lack the right tools, hiring a professional is a safer option. For instance, Window Cowboy in Charlotte, NC, offers expert skylight cleaning. Their team uses advanced cleaning methods to ensure streak-free results and checks seals and flashing for issues.
To maintain your skylights, schedule professional inspections every six months and remove debris regularly. This routine helps prevent buildup and reduces the frequency of cleanings, keeping your skylights clear and safe throughout the year.
