Nothing beats the look of sparkling clean windows, but streaks can be frustrating when you’re trying to get that flawless, crystal clear finish. Double glazed windows require special care to maintain their appearance and efficiency, and using the wrong cleaning methods can lead to smudges, streaks, or even damage.
In this guide, we’ll walk you through the best way to clean your double glazed windows without leaving streaks, ensuring they stay clear, bright, and looking like new.
Why Do Streaks Appear on Windows?
Before we focus on the cleaning process itself, it’s helpful to understand why streaks form in the first place. The most common reasons are:
- Using too much cleaning solution, which leaves a residue.
- Cleaning in direct sunlight, causing the solution to dry too quickly.
- Using dirty cloths or paper towels that spread dust and lint.
- Not properly drying the glass after washing.
Step-by-Step Guide to Streak-Free Windows
Choose the Right Time to Clean
Cleaning your windows on a sunny day might seem like a good idea, but direct sunlight causes the cleaning solution to evaporate too quickly, leaving streaks behind. Instead, clean on a cloudy day or when your windows are in the shade.
Remove Dust & Loose Dirt
Before applying any liquid cleaner, use a dry microfibre cloth to wipe off dust and loose dirt from the window surface. This prevents dirt from turning into a muddy mess when mixed with water. Avoid harsh chemicals like bleach or ammonia-based cleaners and abrasive sponges.
Prepare Your Cleaning Solution
You can use a store-bought window cleaner, but a simple homemade solution works just as well and is more eco-friendly:
DIY Streak Free Window Cleaner:
- Mix 1 part white vinegar with 2 parts water in a spray bottle.
- Add a few drops of dish soap for extra cleaning power.
Apply the Cleaner & Wipe Gently
- Spray the cleaning solution evenly across the glass.
- Use a soft sponge or cloth to gently wipe in circular motions to lift dirt and grime.
- Pay extra attention to any stubborn spots.
Use a Squeegee for a Flawless Finish
- Starting from the top, pull the squeegee down in straight, overlapping strokes.
- Wipe the blade with a clean cloth after each pass to avoid smearing.
Buff with a Dry Microfibre Cloth
Once you’ve squeegeed off the excess water, use a dry microfibre cloth to buff any remaining streaks for a polished, spotless finish. With the right technique and tools, you can achieve streak free, gleaming double glazed windows in no time! Regular maintenance keeps your windows looking great and helps them last longer, improving your home’s appearance and energy efficiency.
