Sharing is caring!


Having windows that look cloudy or hazy can be frustrating and unsightly. This film is usually caused by mineral buildup or a buildup of dust and grime. It can be difficult to remove, but with the right techniques and tools, you can easily clean your windows and restore their clarity. In this article, we will provide you with step-by-step instructions on how to clean windows that have a film on them.

Understanding the Cause of Window Film

Before we dive into cleaning the film on your windows, it’s essential to understand the reasons behind the buildup. The two most common causes are mineral buildup and dust and grime buildup. Understanding the cause of the film will help you determine the most effective way to clean it.

Mineral Buildup

Minerals such as calcium and magnesium can accumulate on your windows and cause a white film. This buildup usually occurs due to hard water in your area. If you have hard water, you’ll likely see this film on other surfaces in your home as well, such as your showerhead and sink.

Dust and Grime Buildup

Dust and grime can accumulate on your windows over time, creating a cloudy film. This buildup is most common in areas with high traffic or near busy streets where pollution and dirt are prevalent.

Tools and Supplies You’ll Need

To clean windows with a film on them, you’ll need a few essential tools and supplies. Here’s a list of what you’ll need:

  • Microfiber cloths
  • Squeegee
  • Bucket
  • Vinegar
  • Dish soap
  • Rubbing alcohol

Step-by-Step Guide to Clean Windows with Film

Step 1: Remove Dust and Debris

Before you begin cleaning the film on your windows, you need to remove any dirt or debris on the surface. You can do this by using a microfiber cloth to wipe down the window.

Step 2: Mix Your Cleaning Solution

Mix a solution of one part vinegar and one part water in a bucket. If your windows have a heavy buildup of mineral deposits, you can add a tablespoon of dish soap to the solution. Dish soap will help break down the minerals, making them easier to remove.

Step 3: Apply the Cleaning Solution

Dip your microfiber cloth into the cleaning solution and apply it to the window. Be sure to cover the entire surface, including the edges and corners.

Step 4: Use a Squeegee

Using a squeegee, start at the top of the window and work your way down, removing the cleaning solution as you go. Be sure to wipe the squeegee blade after each pass to prevent streaks and ensure a clear finish.

Step 5: Rinse the Window

Once you’ve squeegeed the entire window, rinse it with clean water. This will remove any remaining cleaning solution and leave the window clear and streak-free.

Step 6: Spot Clean with Rubbing Alcohol

If there are still spots or streaks on your window, you can spot clean them with rubbing alcohol. Dip a clean microfiber cloth into rubbing alcohol and wipe down the affected area.
