Got 7 houses to clean soon.
We did a test today, we left blackwash on for 10 minutes and washed it off. There was still black marks on the walls, but looks loads better.
We are thinking of soaking the walls with black wash for 1 hour and then using the jet wash with 30ft lance on the lowest setting to wash it all off. What does everything think the results will be like?
Any tips on how to get this looking good? I'm still very new at this.
Cheers
