Pure Water Cleaning - Isn't water just water?

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. Commonly, this is often described as ‘de-ionised water’ due to the filtration process used.

We use the latest high-reach systems which provide us with our super-clean Pure Water to achieve exceptional results. The soft bristle brushes we use remove dirt particles and smears on the glass whilst the pure water can be left to dry naturally without leaving water stains. This technique also means windows stay clean for longer as there is no soap residue to mix with rain and create stains later.

In fact the water we use is put through a 7-stage process before it touches your windows so they are left ultra clean!

1. Water Softening
2. Sediment Filter
3. Carbon/Charcoal Filter
4. Semipermeable Membrane (or RO) Filter
5. Water Polishing
and finally...
6. Additional Water Polishing using on board DI
7. The purified water is heated

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. Pure water clings to pretty much anything it comes into contact with - including dirt!
