Professional window cleaners typically use purified water as part of their cleaning process. This is because ordinary tap water contains dissolved minerals and impurities that can remain on the windows when the water dries. Purified water, on the other hand, helps them achieve cleaner, streak-free results. 

Keep reading to learn more about what makes purified water different from tap water, how it makes a difference in window cleaning, and the role of professional window cleaners. 

Why Tap Water Can Leave Spots on Windows

To understand why purified water is beneficial, you have to first understand the issue with tap water when it comes to cleaning windows. Regular tap water is what’s known as “hard water,” which means it contains dissolved minerals. When it’s applied to glass and allowed to evaporate, it leaves these minerals behind. This can look like white spots, streaks, or cloudy-looking residue and can be difficult to remove, especially with repeated exposure. 

What Makes Purified Water Different

Window cleaners use water that has gone through a purification process, whether via reverse osmosis or deionization, to remove dissolved minerals and other impurities. The goal is to produce water with very low levels of dissolved solids. When this water evaporates, it won’t leave spots or streaks on the glass, creating a crystal-clear finish that tap water cannot achieve.

Let’s take a closer look at the benefits of opting for purified water for window cleaning:

• Fewer water spots: Removing minerals from the water helps prevent spotting as the glass dries. 
• Cleaner, more consistent results: This can help professional window cleaners achieve a uniform finish across large areas of glass, creating a more polished appearance.

• Air-drying: Because purified water doesn’t leave behind residue when it evaporates, windows can air-dry if necessary. 
• Less reliance on harsh chemicals: Purified water systems can reduce the need for traditional cleaning chemicals in certain exterior window cleaning applications. 

Does Purified Water Really Make a Difference?

Water quality matters because dissolved minerals are a primary cause of water spotting. Purified water is especially helpful for large exterior windows, second-story and hard-to-reach windows, homes with many windows, properties in areas with mineral-heavy water, and windows that are difficult to dry manually.

However, purification doesn’t replace proper window-cleaning technique. To achieve professional results, purified water needs to be combined with proper equipment, thorough agitation, correct cleaning techniques, and an understanding of different types of glass and contaminants. 

Can Purified Water Remove Every Type of Window Dirt?

Purified water is highly effective against many types of everyday dirt and grime, but alone, it’s not a universal window cleaning solution. Certain contaminants may require more than just water, including mineral deposits, paint, construction debris, adhesive residue, mineral buildup, and certain organic stains. Professionals may use specialized techniques or cleaning products when purified water alone isn’t enough. 

Why Professional Expertise Matters

Simply using bottled or filtered drinking water isn’t the same as using professionally purified water. The ionization and reverse osmosis processes they use produce much purer water than household filters can achieve. They continuously monitor the water quality to ensure it’s sufficiently pure for window cleaning. 

Additionally, professional window cleaners are equipped with special tools that the average homeowner doesn’t have access to. This includes water-fed poles, which are like long tubes with brushes on the end that draw the water up, allowing technicians to clean windows dozens of feet up in the air without their feet ever leaving the ground. 

Furthermore, trained technicians know when purified-water cleaning is appropriate and when additional cleaning methods are needed. This means that cleaning solutions are only used when needed, the job gets done quicker, and your windows will look better than ever before. 

Why This Matters for Homeowners

Regular professional cleaning can help maintain the appearance and functionality of your windows and glass surfaces. If you’re searching for a local window cleaning company, look for one that uses purified water. It may not seem like a big deal, but it can make a significant difference in your home’s overall appearance. Plus, when you avoid mineral deposits left by hard water, your windows will stay looking fresh for longer — and they’ll be easier to clean, too.
