i have some findings for you, Ive played about with this, OK rinse in on Ive found fan jets an a dual trim mono good for this method, now there is some draw backs there can be some small particles left behind after rinsing i turn flow up but still leaves little bits sometimes, but when dry you cant see them, so on regular cleans its fine, but for first cleans not for me, another issue i find is i rinse on glass anything above ground floor but cant get the knack doing on ground floor and fan jets rinse in off the glass has issues with vents an sometimes a bit of spotting,
now for rinsing off i found pencil jets 1.5mm with a single trim mono, this is perfect for me, draw back its slightly slower than above method but good for grubby jobs an first cleans.
there is no wrong in any method its what suits you really.
