Is it possible to have windows cleaned using pure water only?
Yes ! Pure water window cleaning. No soap, detergent or other chemicals used. How is this possible? Many companies now provide this service. First of all we have to know what does “pure water” mean. Pure water is a purified sort of water free from all contaminants and substances like magnesium, calcium, salt and the like. These tiny deposits in the water are left when water evaporates. These can be frequently seen on glass bathroom shower screens and external windows that are hosed with normal tap water. A lot of vehicles that are washed and not dried off or washed with pure water also end up with spots. To obtain pure water standard tap water must go through a purification process. One of the most common yet effective filtration processes currently available is reverse osmosis (RO). In a reverse osmosis system, regular tap water is passed thru a semi-permeable membrane whereby salt, minerals are rejected and don’t pass through the membrane. The water that passes through the membrane becomes pure water. Salt and minerals in tap water is generally known as Total Dissolved Solids (TDS) which is commonly voiced as mg per litre (mg/L) or parts per million (ppm). TDS is the measure of the purity of water. For a good running reverse osmosis system, it is expected that 85-to-99% of TDS will be reduced. We have found a TDS reading should be between 1 and 10 to give the spot free finish that’s required.
How is the pure water window cleaning done ?
The pure water is stored in a holding tank that is mounted on the specialists truck or made and used onsite depending on the filtration unit. The water is then pumped up an extendable pole that has a brush on the end. The windows are brushed gradually, loosening the dirt then rinsed off with the water. These extension poles are called water fed poles which have been around for many years. The newest poles are made of carbon fibre/graphite mixtures making them a lot lighter and easier to use. These water fed poles are used together with pure water and have been a real game changer.
What are the advantages of using pure water for window cleaning?
When pure water is used for cleaning windows you finish up with a spot free finish on the glass. Using extendable water fed poles significantly decreases or gets rid of the need for ladders which in turn makes the work place a lot safer. This could reduce insurance claims, eliminating the chance of someone falling off a ladder. No chemicals are involved in the procedure, such as detergent or cleaning agents that are routinely used with conventional techniques. This cleaning method is ecologically friendly.
