The Holy Grail of WFP window cleaning has always been a product that would convert a glass surface from phobic to phylic in a single application. Or at the most a double application where the first is used to "deep clean", and the second to apply a coating of silanol functionalyzed nanoparticles.
Some window cleaners have used glass etchants such as hydrofluoric acid to deep clean glass. Which is quite frightening if you know anything about the dangers of this acid. But there are other chemicals such as dilute solutions of sodium hydroxide that will deep clean window glass making it hydrophylic. As for coatings that use functionalyzed nanoparticles;...these are quite common. Most of these are used to created hydrophobic (water hating) surfaces. As for the use of silanol groups (which are quite hydrophylic) to functionalyze nanoparticles, this is also a rather common practice. But it is currently used for a completely different application other than WFP window cleaning.
I write this only to demonstrate that the technology for creating such a product is well within our reach. It is just that no manufacturer has done it yet. So what about any of you manufacturers that are reading this blog. I know you are out there. I know you are reading what I write. And I know you are watching my videos like the one I just posted from my Youtube account. Which plainly shows how to convert glass from phobic to phylic.
