Got this coming up soon, 7 houses together all windows, render and gutters.
Haven't done much of these yet. We did do a test today with black wash, left it on for 10 mins and most of the black came off.
We are thinking of spraying it all up, leaving it for an hour then use the pressure washer with 30ft lance on the lowest setting and wash it all off.
Giving the guys 4 days.
Any tips regarding getting the black off? Or will the hour soak in Blackwash be ok?
Cheers,
