I am just starting with my window cleaning business.
I've been practicing at home tryna git gud before making sales.
Likewise, I've been using water from the hose (hard water). When cleaning a window for a client, are we supposed to use filtered water ? I've noticed some of my windows are sort of streaky. I am not sure if that is due to skill issue or the water. Going to keep practicing though!
Also, where can the cleaning solution be tossed? (palm olive)
