Removing APC from glass

[Duckyscrubs]

I was cleaning out the engine bay of my car and while drying it with the leaf blower the residue which had APC ended up on my windshield. It's showing a brown residue that I can't scrub off. How would you go about getting this off glass.

Is what you are talking about in the lower right corner of the picture? I'm not sure that has anything to do with the APC, but I think if you try an AIO or mild polish by hand it should take that right off.

I'm with Setec in that I woudn't think that was APC induced. I get water spotting and road grime outside of my wiper sweep areas and hit my glass with a few polish passes when I'm doing the paint. Usually at the end of a pad's life on that section of paint I'm working.

I also hit my glass with Duragloss NuGlass about twice annually.

ME too, Love that stuff and its cheap. I use it with a polishing pad on bad spots and they come right out

Thanks guys I'll try out the Duragloss NuGlass and see if that works. I also noticed that I have the same stain on my paint around the engine bay. It isn't as noticeable but will polishing remove that?
