Can't keep a clean, streak free interior windshield.

The problem might be the cabin filter.

If it is worse in cooler weather then likely needs replacement.

When was the last time it was changed?

The Stoners products work great, so it is not the cleaning, it's the input.

Blackfire glass cleaner!! Before I tried it I would have told you I'd shoot myself in the foot before buying a $20 bottle of glass cleaner. It's now one of my favorite products. It's great for deep cleaning. And for successive light cleaning after an initial wash, it takes very little product. I actually use much less glass cleaner than I used to use and my glass is always cleaner. I did my brothers glass yesterday and he immediately noticed that his glass looked better than ever before. This stuff is different.

I agree that expecting near perfect interior glass after 2 weeks is kinda pushing it... Clean all the glass, inside and out at least once a week in order to keep it up to the standards.

I keep a microfiber mitt in my console and when the windshield starts to get cloudy, I pull out the mitt and clean the driver side with the dry mitt when stopped at red lights. Plenty of traffic lights on the way to work, darn it! I do the passenger side when I get to work. Cleans them right off as long as they aren't too dirty. Basically I find myself wiping them down about every 2 or 3 weeks.

Glass is one of the most tedious parts of the car.
0000 Steel Wool with Lubricant (Light Scrubbing)
Two- Three Microfiber Towels (One or Two for Drying, One for Applying)
That should remove an extensive amount of the residue.
