gatting to be a first clean expert now, its minging, mucky and sometimes disgusting,
i carry my stanley scraper , get all the bird poop off, and paint blots.... then soap it up... then leave it a couple of minutes... same with frames (after a good dust down)....
i find the whole thing comes up better when just left a few mins, whilst doing another pane....
i really couldnt clean any other way, to just do the glass and leave a filthy frame, is like changing your undies without having a shower..
but you know what?
the feeling you get ,before and after factor is immense,
job satisfaction ,and being proud you did a good job, speaks volumes
and is worth much more than a quid.!
