Nothing ruins a good window cleaning like streaks that show up as soon as the sunlight hits. If that sounds familiar, you are not alone. Getting windows truly streak-free requires using the right tools and techniques.
The squeegee is one of the most effective tools for cleaning glass, but only when you use it properly. This guide will teach you how to get the most out of your squeegee, including pro tips, common mistakes to avoid, and the professional products that deliver crystal-clear results.
Why a Squeegee Is the Best Tool for Streak-Free Windows
Before getting into the technique, it helps to understand why a squeegee gives better results than cloths, paper towels, or even newspapers.
● No lint or fibers: Cloth often leaves residue, especially when damp.
● Even pressure: A squeegee glides smoothly and maintains full contact with the glass.
● Less waste: No need to burn through a roll of paper towels on each window.
● Faster drying: It removes water completely, which helps prevent streaks and mineral spots.
A good squeegee technique gives your home’s windows the same clear results you see on storefronts and office buildings.
What You’ll Need Before You Start
If you want streak-free results, don’t wing it. A few simple tools can make all the difference.
● A good squeegee does the heavy lifting and leaves a dry finish behind.
● Microfiber cloths help clean up corners and polish away any leftover haze.
● Warm water loosens dirt and makes everything easier to wipe clean.
● A streak-free cleaner makes sure you are not fighting residue or film.
● A towel on the sill keeps drips from making a mess as you go.
Set yourself up with the right tools, and you are halfway to a great result.
The Best Squeegee Technique for Windows
Squeegees are fast, effective, and easier to use than most people think. Here’s how to clean windows like a pro.
Start by Prepping the Glass
● Wipe the window frame and sill to remove dust and cobwebs.
● Spray your glass cleaner evenly across the surface, or apply a soapy water solution with a sponge.
● Cover the glass fully without soaking it. Too much liquid can cause drips and streaks.
Option 1 – Top-to-Bottom Swipe Method (Beginner-Friendly)
This method is simple, easy to control, and perfect for small or standard windows.
How to do it:
- Place the squeegee at the top-left corner.
- Pull it straight down with even pressure.
- Wipe the blade after each pass with a clean microfiber towel.
- Repeat with overlapping strokes across the window.
- Dry the edges and sill with your towel.
Why it works:
✔ Easy to learn
✔ Removes water quickly
✔ Prevents streaks and drips
Option 2 – The S-Curve (An Advanced Technique)
Used by professionals on large panes of glass, the S-curve method is efficient but requires some practice.
How to do it:
- Start at the top-left corner.
- Move the squeegee in a smooth S-shape across the glass.
- Keep the leading edge angled slightly toward the dry surface.
- Wipe the blade after each complete pass.
- Finish by drying the edges and sill.
Why pros use it:
✔ Covers more area in fewer passes
✔ Reduces drips between strokes
✔ Ideal for large windows or sliding glass doors
Pro Tip ✨ The S-curve works best with light, steady wrist motion. Practice on a small window until it feels natural.
What About Small Windows or Mirrors?
The same technique applies, but on a smaller scale. Use a squeegee with a narrower blade (around 6 to 8 inches) for better control on small panes.
For very small surfaces like cabinet glass or framed mirrors, a microfiber towel with Invisible Glass may give you more precision and speed than a squeegee.
Why the Right Glass Cleaner Matters
Even the best squeegee technique can fall short if your glass cleaner leaves behind residue or streaks. That’s why the product you use matters.
Invisible Glass is made specifically for glass — no dyes, soaps, or scents that cloud your finish or attract dust. It cuts through fingerprints, smudges, and tough buildup without leaving a film behind.
What makes it different:
● Safe for tinted windows and coated glass
● Evaporates clean with no streaks or haze
● Lint-free when paired with microfiber cloths
● Works on mirrors, windows, and auto glass
If you're looking for a cleaner that works as hard as your squeegee, this is a great one to keep on hand.
