A good flow of water and a tilt either side of the glass is all that’s needed,the microscopic bits you can see at certain angles in my experience make no difference to the end result they can’t be seen when the window dries.
Makes me laugh when I see people holding back off the glass a foot 18” it’s just not required to get the job done,even on a first clean I’ll use the same rinse but then again I use hot water which is a big advantage anyway.
