Glass polish ?

[kcfirstbuild]

So i want to really clean up my new old soft ray windows and rear window. I used glass cleaner and it just doesn't cut it in some places. There are some scratches too I think i might be stuck with those and thats ok just want to get ride of the spotty areas.

I just read some posts about Bar-keep cleaner and green pad, or 0000 steel wool. What do i want to use with the steel wool, water or some kind of lubricant ?

Will any of these choices hurt the soft ray tint ?
