I started with dawn. More on the sudsy side.. Dealt with streaks etc.. spent more detail time.. But was still a newbie. So that in it's self say's it haha.. Due also in part to learning which rag's were better. Micro, cotton etc.. Moved to the unger soap you can get at home depot. Liked it. But it's hard on the skin. plus the msd's. Bought titan-glass-gleam-4.html">gg4 took a little to get use to. Not as much sud's and the slip is a little less than unger. But the clean quality is outstanding imo. Window's look better using these imo.
Not used e-cover yet. But will prob break down and give it a go. In the near future. Based on what guy's are saying here about it.. Depending on the job. I may use the unger for exterior. Then gg4 for interior.. Using gg4 for tds avg of 150 to 200 maybe overkill. And could use 3.
My 2 cents anyway..
