I use ladder steps got multi function one.
Clean white struts with no-nonsense trigger spray then use scrim or cheap micro fibre to clean, warn custie may not look as new but not far off.
Then obviously use window vac for glass.
I know your on ladder anyway doing white struts but think this would make glass quicker!
I must add the 2 inside connies i have done so far were medium size and slope of roof wasn't high 9 feet suppose.
Done inside roof £60 2.5hrs
other connie was all inside roof windows all frames £150 10pm til 4pm did on a saturday missed grand national

But custie kept on so felt like had to do didn't fancy the all inside one but learnt a few things

Nice lady but p'd me off left most of furniture in connie (step machine-keep fit thing, table, 3 seater wicker seatee, small piano that didn't make any quicker)
but for one of these type jobs i felt like i come out ok,
as i usually burn my fingers
