I'm still new & started WFP. I'm gradually building a customer base but I'm not happy yet with WFP. I'm using a Pure Freedom Trolley with Vikan brush.
I've cleaned my own windows about 6 times now, but even though they are less than a year old with new frames, they are still spotting. You can only see it from inside, but they are there. Just when I think I'm getting somewhere, I do my own windows & my confidence is blown again.
My method is scrub frames, then glass, then rinse. It seems to me that if I cleaned glass only (tricky to totally avoid the frame) I would get better results as the problem is the drips from the frame. The spots are only right at the top of the glass.
So, please, any advice would be welcome.
I have recently upped the flow to 60 and on 1st cleans, scrub frames, then go back and scrub glass only from advice on here. 1st cleans I believe are ok now as the frames are pretty near dry by the time I get to the glass. But in truth, and here is the problem, unless you can see from the inside, I'll never know if they were any good.
