Killian from Cloud 9 was punctual, professional, and did a great job on my two-story house windows, including the granny flat and several skylights. The windows were covered in dust and grime and hadn't been cleaned in a while.

Deionised Water System – Premium Pure Water Cleaning for Crystal-Clear Results
The Importance of Using Deionised Water
Traditional tap water contains minerals that leave streaks, marks, and deposits on glass.
Our deionised (DI) water system removes 100% of minerals and impurities, delivering a perfect, spotless finish every time, even when drying naturally.
Why Choose Cloud 9 Cleaning for Deionised Water System?
-
Pure, Mineral-Free Water: Our RO/DI filtration removes all impurities, ensuring your windows dry crystal clear with zero streaks, marks, or residue.
-
Protects Your Glass Over Time: DI water doesn’t just clean, it helps repel dust, salt, and pollen, keeping your windows cleaner for longer and reducing buildup.
-
Ideal for High-End Homes: Perfect for large glass surfaces, modern architectural homes, balustrades, pool fencing, and waterfront properties.
-
Safe for All Surfaces: No chemicals, no harsh detergents, just pure, ultra-filtered water that’s safe for glass, frames, tracks, and the environment.
How Our Deionised Water Cleaning Works
1. Filtration: Water passes through a multi-stage reverse osmosis and DI system, removing all minerals and contaminants.
2. Deep Scrub: We scrub glass and frames using non-scratch nylon brushes designed for premium cleaning.
3. DI Rinse: Pure deionised water rinses away all residue, ensuring a spotless finish when it dries.
4. Long-Lasting Protection: Your clean stays clearer for longer, DI-treated glass resists dirt, salt, dust, and pollution.
