I have a feeling that those who prefer lightness over cleaning power will try to justify that the supremes aren't any better than extremes, and that's why they are going back to the extreme brush.
For me it's night and day. I used extremes for about a year, and then I noticed I was getting brush strokes on the glass (similar to the poor results Dave had mentioned from WFP). Extremes are only good on very clean glass in my opinion.
I do use pure water additives, but I'm finding the supreme soft hybrid to scrub better than anything I've ever used, it's the splay of the brush that does it.
Snail trails and bird mess is coming off in a few swipes for me.
Am I the only one to find this?
