I have been looking for a good glass cleaner
The best I've found so far is Glass Wax. It comes in a pink rectangular small can.
Used it on the inside glass today 'cause I couldn't get the inside glass clean. It did a great job.
The only bad thing about it is that it you use too much, it can leave a little excess pink powder
around, after wiping, and it leaves white marks on the black plastic area below the wipers.

I also heard that some of the film I am experiencing inside the windshield is from the armor all
I am using on the dashboard. I use very little, and only apply it to the towel first and then just
wipe the dash with it. Do you think that it could be adding to the interior windshield film?

....especially during the hotter months.

SprayWay is I breifly "touched" some wood in the car by accident. The shiny coat went dull and cloudy instantly. I polished the wood with Meguir's plastic polish and it came back OK, but the whole thing scared me.

I spray the Sprayway cleaner on the towel first now outside of the car. Worry about getting it on the dash or anything else.

I use a mild soapy solution and b&w newspaper on the windows

(I hear this is bad if you have tinted windows).

As posted alittle ways down, the ink from the newspaper acts as a very fine polish and leaves the windows very clean. The soap obviously cleans the windows.

Works great, and its very inexpensive.
