It’s a bright morning. You open your curtains, ready to let the light in… and instead, you’re greeted by dusty streaks and smudged fingerprints.
We’ve all been there. Despite our best efforts, glass window cleaning can be surprisingly tricky. Smears, water spots, and even fine scratches can appear if you're not using the right techniques.
So what’s the best way to get it right, and enjoy the clear, streak-free view you deserve?
Whether you're going DIY or considering a window cleaning service in Singapore, here's everything you need to know about how to clean your glass windows effectively and safely.
Start With the Right Weather
Tip: Avoid cleaning your windows in direct sunlight. It might seem like a good idea to clean on a sunny day, but the heat causes your cleaning solution to dry too quickly, leading to frustrating streaks.
Instead, wait for an overcast day. Cloudy skies give you the perfect conditions to wipe without rushing, and without leaving residue behind.
What You’ll Need to Clean Your Glass Windows
Before you begin, gather your tools. Having everything within reach will save you time and effort.
Here’s what you’ll need:
A microfibre cloth (lint-free is best)
A feather duster
A squeegee for streak-free finishing
A bucket or spray bottle
A DIY cleaning solution:
2 cups water (distilled if possible)
½ cup white vinegar
¼ cup rubbing alcohol (70%)
Avoid using hard tap water, especially in areas with mineral-rich supplies — it can leave water spots after drying.
Step-by-Step: How to Clean Glass Windows
1. Dust Before You Wash
Use a feather duster or soft brush to remove loose dirt and dust from the window frame, sill, and screen. This helps prevent scratches during cleaning.
If your windows have screens, remove and clean them separately with water, dish soap, and a soft sponge. Let them air dry before reinstalling.
2. Clean from Top to Bottom
When applying your glass cleaner, don’t spray directly onto the window. Instead, spray your cloth to avoid runoff that can stain or discolour frames.
Wipe in a Z-pattern or overlapping strokes from top to bottom — this is one of the most effective methods for how to clean windows without streaks.
3. Polish With a Microfibre Cloth
After wiping, use a dry microfibre cloth to buff the surface and remove any leftover solution. This final step helps eliminate haze and leaves a sparkling finish.
Why Use a Squeegee?
If there’s one tool that makes a difference in glass window cleaning, it’s the squeegee.
Squeegees are:
Lightweight and ergonomic
Perfect for large glass panels
Great for removing excess moisture and avoiding water stains
Quick squeegee tips:
Replace the rubber blade every 4–6 hours of use
Don’t press too hard, let the squeegee do the work
Use a smooth “S” motion for even cleaning
Check that the rubber blade is clean and undamaged before each use
Don’t Forget the Window Tracks
Even the cleanest window panes won’t shine if the tracks are full of gunk.To clean window tracks:
Vacuum the debris using a crevice attachment
Sprinkle baking soda along the track
Spray with a vinegar and water solution
Scrub with a toothbrush
Wipe dry with a cloth
You can also use a toothpick to get into tight corners, it’s a simple hack that makes a big difference!
Common Window Cleaning Myths (Debunked)
Myth 1: Newspaper Polishes Windows
Modern newspaper ink can rub off on your frames — and the paper is now too thin to clean effectively.
Myth 2: Rain Cleans Windows
Rain only spreads existing dirt and adds mineral deposits. It doesn’t actually clean your windows.
Myth 3: No One Notices Dirty Windows
They do, especially when the sun hits just right. Dirty windows affect natural light, mood, and even property value.
Myth 4: Pressure Washing Is Safe
It might seem efficient, but it can damage glass, flood window frames, and cause long-term issues.
Myth 5: A Window Cleaning Service Isn’t Worth It
If your windows are large, hard to reach, or in a high-rise, hiring a window cleaning service in Singapore is not only smart, it’s the safest and most efficient choice.
