Streak-free clean windows do more than just look nice—they bring in natural light and offer unobstructed views. They create an inviting atmosphere and ensure safety by allowing you to see clearly. So, when you clean your windows, you’re not just wiping away smudges, and you’re opening a view to a brighter world.

In this article, we’ll talk you through how to clean a window without streaks so you can get a sparkling, streak-free finish every time.

But first…

What Causes Streaks on Windows?

Achieving a streak-free finish can be tricky. Residue from cleaning solutions or hard water deposits can be stubborn and leave unsightly marks on the glass, but that’s not all:

  1. Improper cleaning solutions: According to Windows and Doors expert, “Using harsh chemicals or cleaners not designed for windows can leave behind streaks.”
  2. Dirty tools: Dirty or worn-out sponges, cloths, or squeegees can transfer grime onto the glass.
  3. Hard water deposits: Minerals in hard water can leave streaks on windows, especially if the water isn’t thoroughly wiped away.
  4. Incorrect drying technique: Inadequate drying, such as using a damp cloth or allowing air drying, can lead to streaks.
  5. Weather conditions: Cleaning windows in direct sunlight or extreme temperatures can cause cleaning solutions to evaporate too quickly, leaving streaks behind.

Understanding these common culprits can help you tackle streaks and achieve crystal-clear windows, as will using the right tools for the job.

Window Cleaning Materials

  • Glass cleaner solution
  • Microfiber cloths or squeegee
  • Bucket or spray bottle
  • Water
  • Distilled white vinegar (optional)

Choose Your Window Cleaning Solution

Selecting the right window cleaning solution is crucial for achieving streak-free results. There are lots of commercial window cleaning solutions available, but if you want to go au naturel, you can also make your own at home.

  • Commercial glass cleaners: These are readily available and formulated specifically for window cleaning. Look for streak-free formulas, as they’re designed to leave your windows crystal clear.
  • DIY window cleaner: If you prefer a more natural approach, you can create your own cleaning solution. Simply mix one part vinegar with two parts water and spray it onto the window. This homemade mixture is effective in cutting through grime and leaving a streak-free finish. Wipe it off with a microfiber cloth and then dry the window with a clean, dry, microfiber cloth or squeegee.

Use the Right Tools: Microfiber Cloths or Squeegee Blade

Microfiber cloths and squeegees are both effective at cleaning windows without streaks. Microfiber cloths are soft and absorbent, while squeegees can help remove excess water and dirt.

  • Microfiber cloths: These soft, lint-free cloths are designed to absorb and trap dirt, grime, and cleaning solutions. They leave surfaces clean and streak-free. Opt for high-quality microfiber cloths to ensure the best results.
  • Squeegee: A squeegee is a specialist window cleaning tool with a rubber blade that effectively removes cleaning solution from the glass. It’s particularly useful for larger windows or windows with a lot of surface area. Using a squeegee requires a bit of technique, but once mastered, it can provide exceptionally clear results.

Bucket or Spray Bottle

You’ll need a container for your cleaning solution. A bucket is a practical choice for larger windows, allowing you to mix and carry an ample amount of solution.

On the other hand, a spray bottle is ideal for smaller or spot-cleaning tasks. If you use a spray bottle, choose one that has a fine mist setting.


Warm water is an essential ingredient for cleaning windows. It helps dilute the cleaning agents and facilitates the removal of dirt and grime.

You can use tap water, but distilled water is preferred, as it doesn’t contain minerals that can leave streaks.

Distilled White Vinegar (Optional)

Distilled white vinegar is a versatile and eco-friendly addition to your window cleaning arsenal. Its acidic properties help dissolve mineral deposits and cut through stubborn grime.

While it’s optional, adding a small amount to your DIY cleaning solution can provide an extra boost of cleaning power.

How to Get Streak-Free Glass: Step-By-Step Instructions for Streak-Free Window Cleaning

Prepare the Window

Remove any screens or blinds. Clean away any dust, cobwebs, or loose dirt from the window frame and window sills with a brush or vacuum cleaner. Protect surrounding areas from potential drips or spills by using old towels or plastic sheets.

Apply the Window Cleaning Solution

Spray the window cleaner directly onto the microfibre cloth, not directly onto the window. This will help to prevent streaks.

Clean the Window

Wipe the window in a Z-shaped motion, starting at the top and working your way down. This motion is effective for cleaning windows because it helps to prevent streaks.

When you wipe a window in a straight line, it’s easy to miss small areas or to leave behind streaks. By wiping in a Z-shaped motion, you’re more likely to cover the entire window evenly and to remove all of the dirt and grime.

Dry the Window

If you’re using a squeegee to dry your window, start at the top of the window and pull it down in a straight line, overlapping each stroke slightly. This will help to ensure that all of the water is removed and that there are no streaks left behind.

  • Make sure the squeegee blade is clean and in good condition. A dirty or damaged squeegee blade can leave streaks on the window.
  • Apply light pressure to the squeegee as you pull it down the window. Too much pressure can cause the squeegee to chatter, which can leave streaks.
  • If you see any streaks, go back over that area with the squeegee.

If you’re not using a squeegee to dry the window, use a clean microfiber cloth. Simply wipe the window in a Z-shaped motion, like you did when you were cleaning it, starting at the top and working your way down. Again, overlap each stroke slightly.

Buff the Window With a Dry Microfiber Cloth

Check for any remaining streaks and address them promptly. Use a dry microfiber cloth or a second pass with the squeegee. When the windows are dry, buff them with a dry microfiber cloth. This will help to remove any remaining streaks.

If you do end up with stubborn streaks on your windows, you can try removing them with your white wine vinegar mixture. Just spray the solution directly onto the streak and wipe it off with a microfiber cloth.

For really stubborn marks, you might need to use a commercial window streak remover.

7 Top Tips for Cleaning Windows Without Streaks

  1. Washing windows on a cloudy day will prevent the sun from drying the window cleaner too quickly, which can cause streaks.
  2. Use distilled water in your homemade window cleaner to avoid mineral deposits that can cause streaks.
  3. Change your microfiber cloth and dirty water frequently to avoid spreading dirt around.
  4. If you see a streak, simply go back over that area with the microfiber cloth or squeegee.
  5. If you have hard water, you may want to use a water softener in your spray bottle.
  6. If you have tinted windows, use a window cleaner that’s specifically designed for tinted glass panes.
  7. Avoid using paper towels to clean windows, as they can leave behind lint and streaks.

By following these tips, you can clean your windows without streaks and enjoy a clear, sparkling view.
