Summer is a great time to work on cleaning windows on your home, since the weather is beautiful and you'll be able to stay warm, plus your windows will be able to dry quickly under the sun.
The first step toward cleaning your windows without leaving stripes is to purchase the right equipment.
You'll need a good cleaner as well as good rags or better yet, a squeegee with a soft surface that will spread the moisture easily.
Since most windows simply pick up the dust and dirt around them over time, cleaning them should be an easy task; if your windows have heavy-duty cleaning needs you may want to consider contacting a local window cleaning service to make sure the best job is done.
For average windows, start with your window cleaner and squeegee or rag, and make sure if you're using a ladder to reach higher-placed windows.
Now that you're on eye level with the window you want to clean, you can start cleaning at the top of the glass, as this will mean that drips and dirt will fall in a downward direction (towards the ground) rather than dripping over areas you have already cleaned.
Start by spraying your window cleaner on the window, across the top, then passing your squeegee or cloth over the surface.
Try to use small circular motions to first spread the cleaner over the glass at first; after this you can be sure to pick up all the dirt and dust that has settled on your window surface.
When you have wet the entire surface, it's time to finish the job! Use downward strokes in straight lines to complete your the job, and clean your windows without leaving stripes! Once this is done, since you've picked a sunny day to do your cleaning, the windows should dry without stripes in no time.
