Grey marks on facia board

[BNG]

Hi does anyone have an attachment or chemical for a wfp for cleaning the ingrained dark stains on facia and soffit boards, green algee is no problem with virosol, tfr or similar but the grey ingrained dirt stands out especially on bungalows.

I have sourced some non scratch foam pads which work but are small, don't last long and time consuming as you have to scrub by hand up a ladder!

cream cleaner with a stiff brush on your pole system
then just rinse it off
