Windows can allow natural light into indoor areas and provide gorgeous views of your property's lawn and landscapes. Window cleaning may remove fingerprints, smudges, and debris, leaving the glass sparkling and ensuring clear views. However, you might occasionally notice unsightly streaks on the panes. Here's what causes them and what you can do to prevent them.

4 Causes of Streaks On Windows 

1. Worn Squeegee

A squeegee is a window cleaning tool that consists of a rubber-edged blade on a handle. Squeegees can quickly and thoroughly remove water and cleaning products from glass, leaving the surface clean and clear. However, the rubber may dry-rot and become brittle over time, preventing the blade from completely removing moisture, which might leave streaks on panes. Changing the blade one or twice per year can promote the efficacy of these tools and help you keep your windows clean between professional housekeeping appointments. 

2. Lint 

Homeowners often touch-up windows by wiping them with a cleaning solution and paper towels. However, tiny pieces of paper may become dislodged while wiping the glass, leaving streaks of lint that are especially noticeable when sunlight shines through the panes. Using microfiber cloths, which are tightly woven and highly absorbent, can provide streak-free results. 

3. Product Residues 

Glass cleaning products may contain oils and detergents leave greasy streaks or cloudy film on panes. Additionally, alcohol- and ammonia-based cleaners evaporate quickly, possibly even before you get a chance to wipe them off windows, making splotches and streaks more likely to form. Professional window cleaning companies use a solution of distilled vinegar diluted with water, which can effectively clean glass without leaving any cloudy or filmy residues. 

4. Hard Water

Hard water contains trace minerals such as magnesium and calcium. Washing windows with this fluid may cause hard mineral deposits to form on the glass after the water evaporates, leaving chalky streaks and spots. A professional cleaning service may safely remove these buildups without scratching or damaging the panes. You can prevent deposits from forming by cleansing your windows with distilled water and a vinegar-based cleaning product.
