Nothing much to add here, reckon the basics have been well covered...
But where using a sprayer is concerned I now use pure water with a little isopropanol added to it.
Pure water alone is is fine, but adding the isopropanol gives you something to cut through grease and also speeds up drying.
Used with a good quality flat weave microfibre cloth you can clean the glass and leave it quite damp and it will dry out perfectly.
That is of course on repeat clean work where the glass is not too grimy, oh and your cloth needs to be clean too.
I watched the guys on the stand at the cleaning show who had the very expensive method of using WFP inside. Which is basically spraying a fine mist of pure water onto the glass and using their special pads on a pole to wipe the glass, even when left wet it dried out fine.
Using pure water in a sprayer and wiping with a microfibre is more or less the same thing.
Even better though with the addition of the isopropanol!!
