Your absolutely right on this. That is the main reason why watered guys are looking to revert the glass back to hydrophilic. And most polishing processes from scratch removal with glassrenu, to hardware removal with mr. Hardware, hand buffing diamond magic or even bar keepers friend ttansforms the glass back. The wfp guys don't have to scrub or rinse as much. The holy grail of window cleaning.
The dilemma is doing it to the window. I have a hard time seeing guys taking the time and effort to climb up a ladder take an orbital or oscillating tool to polish a second story windows. Just so next few time they can rip through a job next time with regular water. Then the question is how does the glass stay that way? Would you want to do it to storefront glass? Could you even market it to customers? What are the consumer benefits? I see our benefits but have a hard time seeing even the property management company buying into that idea for easier maintenance. If they do jump on the idea I can see storefront guys losing out to day porters running around with a garden hose splashing the windows.
If there is an quick easy and affordable way to apply it while routinely cleaning the glass then its a game changer.
Could/do you get a similar result if you "polish " the glass with 3M white scrub pad?
I love the theory, but I think we would have better luckwith the super hydrophobic coating. That application look super quick and easy. Doesn't eliminate pure water so maybe that creates a bigger problem. I would like to see it tested in a shower. Half hydrophobic and half hydrophilic.
Years ago I tried "Sheer Glass" and nano ultra to change glass to hydrophilic it worked for 6 month's ish, just took to long the polish for the end result. That's why I got into Enduorshield. And I am not in love with it either for cleanning purposes but it dors what its suppose to do. And it's easyfor residential clients to get behind.
