Why didn't anyone point out that the customer said they were streaky, now I'm not sure what she meant with that, because I don't think I have ever left behind streaks, spots and brush marks sure, but streaks? The only time customers said that to me, they were on the inside. They were convinced that they were on the outside, so I went over, dragged my finger over the glass, and said, see? It's on the inside, customer embarrassed of course.
It's always imperative that you get to the bottom of what the marks are on the glass, streaks, smears, spots? Other? Only then you can get a clear understanding of what the problem is and how it got there in the first place, I think that aspect of wfp takes the longest to understand, the pure analytical side of figuring out why a certain window didn't come up right, sure some are blantantly obvious, but some do take a bit of headscratching, and sometimes you just have to face the fact that wfp isn't suitable for it, and do tops only, that's definitely something that needs to be learned, and to keep an open mind about the tools that you use. Customer satisfaction is key, not the 'oh I can't be bothered to fill my bucket cuz wfp is twice as quick, even though I do leave spots on unsuitable windows'. Clean windows is the goal, and using any tool possible to get to that goal is allowed to a certain extend, keeping your own safety and others in mind.
It's really nothing different then traditional, it just requires more brainpower to figure out, that's why some traditional windows cleaners will never get it like somebody once said. It's got a lot to do with not being stuck in your ways, and have an open mind. Or of course, a lack of the aforementioned brain power. (
