I used to stick an applicator on the end of an extension pole and scrubbed. Then i used to stick the squeegee on there and detail as best i could.
If the roof was glass i would finally wrap a scrim around the squeegee and try to wipe away whatever was remaining.
I dunno why i replied to this post as it's knackered me just thinking about all that hard work.
wfp all the way.
