Have you ever cleaned a commercial window only to notice streaks or water spots minutes later? The culprit isn’t always your technique often, it’s the water you’re using. Water purity is a game-changer in commercial window cleaning, affecting both the quality of your results and the longevity of your windows and equipment. In this guide, we’ll explore why purified water matters, how professionals use it, and tips to get streak-free windows every time.
What Is Purity Water in Commercial Window Cleaning
Purity water in cleaning is water that has been filtered to remove minerals, salts, and impurities. Unlike tap water, it won’t leave streaks, spots, or residue, making it ideal for achieving crystal-clear, spotless windows and glass surfaces.
Not all water is created equal. Tap water often contains minerals, salts, and dissolved solids that leave behind streaks and residues. Purified water, on the other hand, has been filtered to remove these impurities. The main types include:
- Deionized (DI) water: Removes almost all mineral ions, perfect for streak-free cleaning.
- Reverse osmosis (RO) water: Filters water through a semipermeable membrane to remove most impurities.
- Distilled water: Boiled and condensed to leave minerals behind, ideal for small-scale cleaning.
These differences may seem minor, but even trace minerals in tap water can leave noticeable residue on glass surfaces.
Why Water Purity Matters Window Cleaning
Clean water is key for streak-free windows, longer-lasting tools, and using fewer chemicals. Pure water makes cleaning easier and more effective. Below we explain in detail why water Purity matters for window Cleaning
