Cleaning Supplies

You will need several common household items to clean your windows. These supplies are quite affordable and will ensure a streak-free finish.

Commercial Glass Cleaning Formula

Distilled white vinegar is a great choice when creating a homemade glass cleaning solution. Vinegar does not leave behind a film that causes dust to stick to your window. 


Most people either do not use a squeegee or do not know how to use it properly. Squeegees are designed to remove excess liquid from your glass and wipe away all traces of dirt from your windows.

Microfiber Cloths

Microfiber cloths are the best choice for wiping glass dry and achieving a streak-free finish. Paper towels and cloths made of materials other than the polyester and nylon mix of microfiber, leave lint behind and increase the risk of streaks.

 Spray Bottle

If you will be making your own glass cleaning formula, you will need a spray bottle. When choosing a spray bottle, look for one with an adjustable nozzle. A chemical-resistant bottle with measurement markings will also help you get the correct vinegar to water ratio when mixing your natural glass cleaning formula.

How To Clean Glass Without Leaving Streaks

You can get a streak-free finish by following our window cleaning instructions. These four easy-to-follow steps will have your windows looking amazing in record time.

Step One – Collect Your Window Cleaning Supplies

Window cleaning only requires a couple of supplies, including window cleaner, a squeegee, and a microfiber cloth. If you will be making your own homemade glass cleaner, you will also need a spray bottle.

The recipe for streak-free homemade window cleaner is one cup of white distilled vinegar and one cup of water. Pour this solution into your spray bottle and gently shake to mix the formula.

  • Pro Tip: Use distilled vinegar to prevent hard water deposits from forming on the glass.

Step Two – Spray Your Window with the Cleaning Solution

After spraying the glass with the window cleaner, allow the solution to remain on the glass for a minute or two. If the glass is extremely dirty, use a damp cloth or paper towel to pre-wash the window and remove excess dirt before spraying on your cleaning solution.

  • Pro Tip: Clean your windows on a cloudy, cool day to prevent your window solution from drying too quickly, which can cause streaks.

Step Three – The Squeegee Makes It Easy

Squeegees help prevent water spots, conserve cleaning solution, and speed up the window cleaning process. The squeegee blade must be wiped in between strokes, which ensures the dirty water is not being transferred back onto the glass.

  • Pro Tip: Squeegee from top to bottom using horizontal strokes.

Step Four – Use a Microfiber Cloth and Wipe the Window Dry

The polyester and nylon makeup of a microfiber cloth lifts and traps dirt and grime from your windows. When drying windows with a microfiber cloth, wipe in a circular motion to reduce the risk of streaks.

Step Five – Use Dish Detergent as a Last Resort

If your windows are especially dirty, dish detergent can help cut through the grime. Mix a half teaspoon of dish soap with two cups of warm water and a quarter of a cup of white distilled vinegar and place in a separate spray bottle. Spray the window with this formula and squeegee dry.

Pro tip: The dish detergent may leave a film that attracts dust. You can counteract this effect by rinsing your window with clean water and wiping it dry with a paper towel. Then, follow our step-by-step instructions listed above.

Final Thoughts

A hurried, sloppy cleaning attempt can also cause streaky windows. The technique is just as important as having the right supplies. Take your time, use the proper tools and techniques for a streak-free finish.
