Just wondering how persons tackle these .
Done a few Conny roofs and full house facia cleans .

I use TFR , Virosol And Ubik2000 .
Think Virosol and TFR are the best .
Sometimes with Hot .

Plus CIF clean

Hardest part is getting  into them fancy rail bits .

Is a soft brush the best .

Virosol and soft brush, YES

[wpclean]

If you use TFR, and angle the brush so it is horizontal to the pole, usually does the trick

i dont agree!soft brushes are rubbish for cleaning the algae from finials on conny roofs.you need a good stiff brush IMO.

I use a stiff radius sill brush which is much better for agitating the dirt after a good soak with virosol.

I find an old flock brush to apply a cleaner and agitate works well.
