Anyone know who made the link between pure water and window cleaning.  I can remember my dad cleaning windows in the 70, s with pure water, he was using tablets in the water, it did not work and soon gave up on it.

I thought it only came about late 90's and took me til 2010 before I started being convinced by it

That'll be because it wasn't pure in that case.

Over here (uk) pure water was started to be used in the late 1990's by a company called over the top  which I think became ionics

I heard that a contractor cleaning a large glass roof in a shopping a centre with a hose pipe and polls
found it was a better finish if they cleaned it in the rain and looked into the reason why.

They later put a filter inline on site, then another to make it a better finish

Then they done the same with really tall window and progressed to processing the water off site and filling a tank in the van.

Not sure where or who this was though
