How to Clean Windows Perfectly

We’ve all been there—after spending ages cleaning your window glass, you step back only to see streaks, smudges, and missed spots. Frustrating, isn’t it?

Whether it’s the constant rain, dust from the roads, or just everyday grime, keeping dirty windows clean can feel like such a chore.

But with the right approach and a few tricks, you can get those glass windows looking crystal clear without the hassle.

Materials for Cleaning Windows 

A variety of cleaning tools

Before you begin the window cleaning process, gather the right tools for the job. Using the correct materials is key to achieving streak-free glass windows:

• Microfibre cloths: Ideal for cleaning and drying glass surfaces without leaving lint behind.

• Squeegee: Essential for removing homemade window cleaning solution and preventing streaks.

• Spray bottle: Fill it with either a store-bought glass cleaner or a homemade window cleaning solution of water and white vinegar.

• Bucket: To mix your window cleaning solution.

• Optional extras: A razor blade for scraping off stubborn spots like paint or stickers, and a step ladder for hard-to-reach window frames.

How to Clean Different Types of Windows

1. Single/Double-Hung Windows

These windows can be tricky because of the separate sashes. Tilt the sashes inward if possible and clean one at a time, using the same steps outlined above.

2. Sliding Windows

Sliding windows often have tracks that collect dirt and debris. After cleaning the glass, vacuum the tracks and wipe them down with a damp cloth.

3. Bay and Bow Windows

These larger windows can be more time-consuming. Break down the task by cleaning one pane at a time, ensuring you reach all corners and edges for a complete clean.

4. Glass Doors

Glass doors, such as patio or balcony doors, should be cleaned the same way as windows. Given their larger size, you may want to work in sections to ensure a streak-free finish.

Preparation: When and How to Start Cleaning Windows

Timing matters when it comes to the window cleaning process.

The best time to clean your glass windows is either early in the morning or later in the afternoon.

Avoid cleaning them in direct sunlight, as the heat causes the window cleaning solution to dry too quickly, leaving streaks behind.

Before starting, clear the area around the window frames by moving any furniture or items that could get in the way.

If you’re cleaning windows on the second floor or higher, make sure to use a sturdy step ladder and take necessary safety precautions.

Step-by-Step Window Cleaning Guide

1. Dust the Windows First

Start by wiping away any dust, cobwebs, or dirt from the window surface. A dry microfibre cloth or a duster works well for this.

Dusting first ensures you don’t end up with a muddy mess when you apply the cleaning solution.

2. Prepare Your Cleaning Solution

A few drops of white vinegar mixed with water in a spray bottle is often the best solution for cleaning windows.

If you prefer, you can also use a commercial glass cleaner, but make sure it’s appropriate for your window type.

3. Clean the Windows

Spray the cleaning solution generously on the window, starting from the top. 

Use a microfibre cloth or sponge to gently scrub the window, focusing on areas with more grime.

Once the entire window is covered, it’s time to use the squeegee.

Dealing with Tough Stains

For windows with tougher stains like bird droppings, paint splashes, or hard water spots, you might need to take extra measures.

A razor blade can be used to carefully scrape away stubborn spots. Be sure to keep the window glass surface wet while scraping to avoid scratches.

For hard water stains, a few drops of vinegar and baking soda works wonders.

4. Squeegee for a Streak-Free Finish

Begin at the top of the window, pulling the squeegee down in one smooth motion.

Wipe the blade clean with a cloth after each pass. Work your way from top to bottom, overlapping each stroke slightly to ensure all cleaning solution is removed.

5. Dry and Wipe

Use a dry, lint-free cloth or paper towels to wipe any remaining moisture from the edges and corners of the window frame.

Pay special attention to the frames and sills, as water can sometimes collect here.

Common Window Cleaning Mistakes to Avoid

1. Cleaning in direct sunlight

The heat will cause your cleaning solution to dry too quickly, leaving streaks on the glass.

2. Using harsh chemicals

Choosing natural cleaning solutions over harmful chemicals

Some chemical cleaners can damage the glass or window frames. Stick to gentler solutions like water and vinegar.

3. Ignoring the drying process

Skipping the drying step can result in water marks. Always finish with a dry cloth or paper towel to ensure a polished look.

How Often Should You Clean Your Windows?

In Singapore, the frequency of window cleaning depends on your environment.

If you live in a busy area with construction or near a major road, your windows will likely need more frequent cleaning, perhaps every month or two.

For others, a seasonal clean—around four times a year—should suffice.
