Hi all, Well, I have been practicing and cleaning windows and my cleaning is getting better. I am not over confident at fanning the window or methods like chopping down the mountain. I do pulls across and down, but I still get little lines on the window, I cleaned my rubber and the rubbers are new, only cleaned about 40 windows on them and other one about 20. since changing. If i pull across I get multipul lines sometimes or like scuff marks, its really annoying me now. Also the sies of windows have lots water left, the unger channel i have and unger rubber in it seems weak at the ends and does nto cleaner water away well on tops and sides, I think I maye have to shorten the rubber length out of each end its about a cm odd. I dont no if its the amount of soap water i use, I am getting a decent soap but not too much. I have to detail alot and use so many unger and ninja micro cloths. Any advice, is my rubber **** or is it just a matter of getting the right distance and style. Some windows are great, just these bloody lines. I have looked on line but wondered if anyone had advice and also any really good vids links. Thank you very much.
