How does pure water work?
Tap water (city water) has a number different kinds of dissolved solids held in suspension in the water. When the water is purified these solids are removed: however, pure water wants to return to it’s naturally dirty state. Pure water attracts the dirt from the surface being cleaned like a magnet. It collects the dislodged dirt, becomes dirty water, and drags that dirt down to the ground with it. Once the pure water has taken all of the dirt away, pure water will be the only product left on the surface. It will dry clean and spot free.
What are the real world implications?
Pure water cleaning is great in principal, but there are several obstacles the cleaner will need to overcome to get great results.
The general issues are as follows:
1.) Either carry pure water or make pure water on demand
2.) Then pump that water to a nozzle and brush.
Most pure water cleaning of building glass is done with an extendable pole that has a nozzle and brush attached to the end. Some pressure washing systems also use pure water to avoid spotting i.e. Car Dealerships.
Note on Self-Cleaning glass:
Self Cleaning glass sold by Pilkington and PPG have a coating applied that turns the glass Hydrophilic. The dirt does not collect into droplets and therefore does not accumulate into spots. This glass needs water, generally exposed to the rain to actually be self cleaning, This means that Self Cleaning Glass installed in an alcove, under an awning or places with little rain will not self clean. This makes this glass easiest to clean with pure water.
