Skylight windows are a beautiful feature in any home—they flood rooms with natural light and open up the ceiling like a window to the sky.

But keeping them clean, especially from the inside, is easier said than done. I used to dread the job myself, thinking it required a professional.

But after trying a few different methods, I found that with the right tools and a bit of know-how, cleaning skylight windows from inside can be a simple DIY task.

Here’s exactlywhat i say on how to clean skylight windows from inside —from gathering supplies to leaving the glass streak-free.

Why Should I Clean Skylight Windows from the Inside?

Do I really need to clean skylight windows from inside?

Absolutely. Over time, dust, grime, and even spider webs can build up on the interior side of skylight windows. This not only blocks natural light but can also trap moisture, leading to issues like mould in sealent or water staining.

How often should I clean skylight windows indoors?

I usually clean mine twice a year—once in early spring and again in autumn. However, if you live in an area with high humidity or have cooking and bathroom skylights, you might want to do it more often.

Can dirty skylights affect light and heating in my home?

Yes. Dirt and film can reduce the amount of light that enters your home, making rooms feel duller and cooler. A clean skylight can actually improve your home’s energy efficiency by letting more sunlight in during the winter months.

What Do I Need to Clean Skylight Windows from Inside at Home?

What tools help clean skylights from inside safely?

Here’s what I keep in my skylight cleaning kit:

• Telescopic window cleaner with interchangeable heads
  
• Microfibre cloths
  
• Squeegee
  
• White vinegar and water (for DIY cleaning spray)
  
• Spray bottle
  
• Step ladder (if the skylight is low enough)
  
• Rubber gloves
  

Should I use a telescopic window cleaner for skylights?

Definitely. If your skylight is high or difficult to reach, a telescopic pole is the safest and easiest way to clean it without climbing. It helps me get into corners without leaning dangerously.

How to Clean Skylight Windows from Inside – Step-by-Step Guide

Step 1 – How do I remove dust from skylights?

First, I use a dry microfibre cloth attached to my telescopic tool to gently remove any dust or cobwebs. I don’t ignore this step—spraying cleaner onto dusty glass just makes muddy streaks.

Step 2 – What’s the best way to apply window cleaner?

I mix a DIY solution using 1 part white vinegar to 3 parts warm water in a spray bottle. Then, I spray it generously onto the skylight surface. Vinegar cuts through greasy films and works really well on glass.

Step 3 – How do I clean skylight glass without streaks?

Using a clean squeegee or another microfibre pad, I wipe the glass in long horizontal strokes, starting from the top. I always overlap slightly to avoid streaks and use a dry cloth to wipe the edges.

Step 4 – Should I clean skylight frames and corners too?

Yes! Frames can trap dust and moisture. I take a smaller cloth and gently wipe around the edges, seals, and any crevices. If I see any signs of mould, I use a diluted vinegar mix to kill it.

Step 5 – How do I dry skylights after cleaning?

Once I’ve cleaned the glass, I go over it one last time with a dry cloth or pad. This step helps prevent new dust from sticking and keeps things looking spotless.

What Is the Best DIY Cleaner for Skylight Windows?

Can I clean skylight windows with vinegar and water?

Yes, and that’s my go-to! It’s eco-friendly, affordable, and doesn’t leave streaks like some chemical sprays. I just mix it in a 3:1 water-to-vinegar ratio.

Are there safe eco-friendly cleaning solutions?

Aside from vinegar, a few drops of lemon juice in water or a splash of mild washing-up liquid can work too. These are great if you’re sensitive to vinegar’s strong smell.

Should I use shop-bought glass cleaner or make my own?

I’ve tried both. Store-bought sprays like Method or Ecover work well, but I often prefer DIY versions for their cost and gentleness on window seals.

Is It Safe to Clean My Skylight Windows from Inside?

Do I need a ladder or long-handled window cleaner?

When the skylight is within reach, a step ladder with rubber feet is fine and best. For higher ones, I always use a telescopic pole with a stable base.

What safety tips should I follow when cleaning skylights?

Here’s my go-to checklist:

• Never clean skylights when alone at home
  
• Always place the ladder on an even surface
  
• Wear shoes with grip soles
  
• Use tools with non-slip handles
  
• Lay a towel or sheet below to catch any drips
  

Can I clean skylights alone or should someone assist me?

If I’m using a ladder, I always ask someone to stay nearby—just in case. Even for simple cleaning, safety comes first.

What Are Some Easy Tips for Cleaning Skylight Windows from Inside?

Here are a few tips I’ve learned through trial and error:

• Clean on a cloudy day to avoid streaks
  
• Dust first, then spray—don’t skip it!
  
• Place towels underneath to protect your floor
  
• Use microfibre cloths—they’re streak-free
  
• Work in sections if you have multiple skylights
  

What Mistakes Should I Avoid When Cleaning Skylights from Inside?

Can I damage skylight glass using the wrong cleaner?

Yes. Avoid abrasive cleaners, scouring pads, or anything acidic beyond vinegar. These can scratch the glass or damage UV coatings.

Why shouldn’t I ignore the window seals and frames?

Mould and condensation love these areas. If they’re not cleaned regularly, they can cause rot or leakage—especially with Velux or older wooden frames.

Is it risky to overuse water on roof windows?

Yes. Excess water can seep into seams and cause leaks. I spray lightly and always dry the glass and frame after cleaning.
