1. Professional Window Cleaning

For professional window cleaners, achieving a flawless, streak-free finish isn't just a goal; it's a non-negotiable standard. This is where deionised (DI) water becomes an indispensable tool. Unlike tap water, which contains dissolved minerals like calcium and magnesium, DI water has had these impurities stripped away. When tap water evaporates on glass, it leaves behind these minerals, creating unsightly white spots and streaks. Deionised water, being pure H₂O, evaporates completely, leaving nothing behind but crystal-clear glass.

This method, often called the 'reach and wash' system, typically involves using a water-fed pole. These telescopic poles pump DI water up to a soft-bristled brush, allowing cleaners to scrub windows from the safety of the ground. The pure water loosens dirt, and a final rinse washes it away. Because the water is deionised, there's no need to squeegee the glass dry, saving significant time and labour, especially on large commercial buildings or hard-to-reach residential windows. The result is a pristine finish that stays cleaner for longer, as there is no sticky soap residue left to attract fresh dirt.

Real-World Applications

The impact of this technique is most visible in high-stakes environments where appearance is paramount:

• High-Street Retail: Chains rely on DI water systems to maintain showroom-quality windows that attract customers.
