The science
The science behind pure water cleaning
Our Pure H2O cleaning system uses highly purified water to clean exterior glass, frames and other suitable surfaces — without relying on traditional cleaning detergents.
How can water clean without chemicals?
Ordinary tap water contains dissolved minerals and salts, such as calcium and magnesium. When normal water dries on glass, these minerals can remain behind and cause streaks or water spots.
Take the minerals out and you take the spotting problem with them.
Purified to almost zero dissolved solids
Our water passes through specialist purification technology, including reverse osmosis and de-ionisation, which removes the vast majority of dissolved minerals and impurities.
The result is extremely pure water with a very low Total Dissolved Solids (TDS) reading.

Typical readings for a mains supply in our area — actual figures vary by postcode and are checked on site with a TDS meter.
How it works
Why does pure water clean so effectively?
Because purified water contains very few dissolved minerals, it readily picks up soluble dirt and residues from the surfaces it contacts.
Brush, flow, rinse
We combine this purified water with professional water-fed poles and specialist brushes. The brush agitates and loosens dirt while a continuous flow of pure water carries the contamination away.
The surface is then thoroughly rinsed with purified water.
Unlike traditional window cleaning, there is no need to squeegee the glass dry.
Because our purified water contains virtually none of the minerals responsible for spotting, the remaining water can evaporate naturally — leaving the glass clean, clear and streak-free.
In short
Cleaner technology. Excellent results.
- Reverse-osmosis purified water
- De-ionised for extremely low mineral content
- No detergent residue left on the glass
- Reaches frames, sills and difficult areas
- Dries naturally without mineral water spots
- An effective modern alternative to traditional window cleaning
