Should window cleaners leave windows wet?

Allowing the water to dry on its own helps ensure that no additional residues from cloths or towels are left behind.

Window cleaners often leave windows wet intentionally, and there are several reasons for this practice:

Use of Purified Water: Professional window cleaners typically use purified water, which has been treated to remove minerals and impurities. This type of water dries without leaving streaks or spots, resulting in a clearer finish when it evaporates naturally.
Natural Drying Benefits: Allowing the water to dry on its own helps ensure that no additional residues from cloths or towels are left behind. If a cleaner were to dry the windows with a cloth, any impurities in that cloth could transfer back onto the glass, potentially leading to streaks or marks.
Optimal Results: The evaporation of purified water can enhance the cleaning effect, as it leaves behind a clean surface without any chemical residues. This method is particularly effective in achieving a streak-free appearance, which is essential for professional window cleaning services.

Leaving windows wet is a strategic decision by window cleaners to maximize cleanliness and minimize streaks, utilizing the benefits of purified water and natural drying processes.

How does purified water improve window cleaning results

Purified water significantly improves window cleaning results due to its unique properties and the methods used in the cleaning process. Here’s how it enhances the effectiveness of window cleaning:

1. Elimination of Minerals and Impurities

Streak-Free Finish: Purified water is free from minerals like calcium and magnesium, which are commonly found in tap water. These minerals can leave streaks and spots on glass surfaces as they dry. By using purified water, window cleaners achieve a clear, streak-free finish upon evaporation.
No Residue: The absence of impurities means that even if some water remains on the glass after cleaning, it has minimal chance of leaving any residue. This results in windows that not only look clean immediately but also stay cleaner for longer periods.

2. Enhanced Cleaning Action

Bonding with Dirt: Purified water has a natural tendency to bond with dirt and grime. When sprayed on a surface, it seeks out impurities to attach to, making them easier to rinse away during the cleaning process. This action helps remove stubborn dirt more effectively than regular water.
Natural Detergent: The cleaning process utilizes purified water as a natural detergent, eliminating the need for harsh chemical cleaners. This is not only safer for the environment but also beneficial for indoor air quality.

3. Efficient Cleaning Process

Use of Water-Fed Poles: The integration of purified water with water-fed pole systems allows window cleaners to reach high windows safely from the ground. This method is efficient and reduces the time required for cleaning while maintaining high standards of cleanliness.
Thorough Cleaning: The combination of soft brushes and continuous flow of purified water ensures that all parts of the window, including frames and sills, are cleaned thoroughly without leaving behind any debris or residue.

4. Long-Lasting Results

Reduced Frequency of Cleaning: Since purified water leaves windows cleaner, they tend to stay cleaner longer, reducing the frequency of required cleanings. This can lead to cost savings over time for both residential and commercial clients.

Using purified water in window cleaning not only enhances the immediate results by providing a streak-free finish but also contributes to a more efficient and environmentally friendly cleaning process.
