About Us

The term Pure Water in window cleaning describes ordinary tap water that has been filtered through a purification system, to remove all the natural minerals. This water is often described as ‘deionised water’. NEXAR Services produces this “pure water” using the latest technology equipment which is an RO (Reverse Osmosis) System.

The reason for this is that pure water dries to leave a completely crystal clear finish, as opposed to general tap water that dries to leave minerals on the windows, which is the reason for hard water stains and unsightly white spotting.

When applied to Window Cleaning, using pure water means that there is no need to squeegee the water from the window. Providing you have agitated (scrubbed) the dirt and rinsed the window thoroughly, you can leave it wet!

Clean and Efficient

Pure water gets windows remarkably clean by acting as a lubricant that breaks the bond between dirt and glass, allowing all the contaminants to be rinsed away. Negating the use of harsh cleaning chemicals, using pure water with water-fed poles has also proved to be extremely efficient in terms of labor, cost, and productivity.

Safety

OSHA standards and stricter health and safety laws concerning ladders have made the water fed pole system using pure water a superior choice for commercial outdoor window cleaning. Because some poles are extendable up to 5 stories, workers can keep their feet on the ground for most jobs, eliminating a myriad of safety risks and minimizing worker injuries.

Cost Savings

Using a pure water window cleaning system simplifies the process of outdoor window cleaning, increases worker safety to help minimize workman’s comp, and eliminates the need for costly lifts and scaffolding. Also, since pure water creates a clean, residue-free glass surface, the time between cleanings can be lengthened—saving time and money.

Environmentally Friendly

One of the eco-friendliest features of pure water cleaning is that you can often forego using chemical cleaners that can be potentially harmful to the environment and workers. Using a water-fed pole and brush system, pure water acts a natural detergent and the runoff from the cleaning process doesn’t harm the plants or grass growing at the base of the building.

Traditional window cleaning as its simplest includes a bucket of water, a ladder and squeegee. This approach may produce an acceptable result for small or internal jobs, but the tap water used as the basis for cleaning is ineffective when it comes to performing professional window cleaning jobs.

Tap water contains impurities, hopefully most of which are common and purposely introduced to provide safe drinking water. If you were to take a TDS meter and measure the level of impurities in tap water (measured in parts per million), you would likely see a reading of 100-200 mg/l, although safe drinking water can register higher values. 

While safe to drink, you don’t necessarily want to clean with tap water given its inherent impurities. Unless you’re able to remove 100% of the water during the window cleaning process, once the water evaporates, what’s left behind are these impurities – the culprits in causing undesirable spots and streaks.
