If you have seen a window cleaner using a long pole with a brush on the end and a hose running from the van, you have seen pure water cleaning. It is how professional window cleaning companies work today, and it is how every Yorkshire Pro round runs. Here is how it works and why it gives better results.
What is pure water?
Ordinary tap water contains dissolved minerals such as calcium and magnesium. When tap water dries on glass, those minerals are left behind as spots and streaks. Pure water has been filtered, usually through reverse osmosis and deionisation, to remove almost all of them.
Because it is so pure, the water actively attracts and dissolves dirt. And when it dries, there is nothing left behind. That is why windows cleaned with pure water can be left wet and still dry crystal clear.
How a pure water clean works
- The van: our vans carry tanks of purified water and hose reels feeding the poles.
- The pole: lightweight carbon-fibre poles extend to reach upstairs and high commercial windows from the ground.
- The brush: a soft brush at the top agitates dirt from the glass, frames and sills while pure water flows through it.
- The rinse: a final rinse carries the dirt away, leaving only pure water to dry spot-free.
Why it is better
A cleaner finish
Traditional methods use detergent, and any residue left on glass attracts dirt. Pure water leaves no residue, so windows stay cleaner for longer. Frames and sills are cleaned at the same time.
Much safer
Falls from ladders are one of the most common causes of serious injury at work. Cleaning from the ground keeps our team safe and means no ladders resting against your walls, gutters or conservatory.
Better for your home and garden
No chemicals run into your borders or onto your patio, and nobody needs to climb over plants to reach a window.
Reaches more
Upstairs windows over extensions, dormers, skylights, conservatory roofs and high commercial glass can all be reached from the ground, which makes the job quicker and the result more consistent.
When we still use a squeegee
Some windows suit a traditional clean: small leaded panes, internal glass and certain ground-floor doors. Our team carries both, and uses whichever gives the best finish.

Quick answers
- Is pure water cleaning as good as a squeegee?
- For most glass it is better, because frames and sills are cleaned too and no detergent residue is left behind. We still use a squeegee where a traditional finish suits the window.
- Why do windows look wet after a pure water clean?
- The final rinse leaves pure water on the glass. Because it contains no minerals, it dries clear without spots or streaks.
- Is it safe for my garden and pets?
- Yes. Pure water is just water with the minerals removed. No chemicals run into your borders.
