Here's my 2 cents, I'm on my first year with my Econo. In the beginning cleaning the glass was just like most people here were saying........a real pain with the hard to remove brown film on the glass. I started using a razor blade but that got old. Then I tried a small piece of I think they call Scotch-Brite? I used a small green piece wet with plain water, brown film came right off. But here's the odd part, after that day I haven't need to use it again, just plain water on a paper towel takes it right off.......absolutely no scrubbing, then I just dry it with another paper towel. Perfectly clean glass everyday. Hope that helps someone.
