I've tried 3 different kinds of glass cleaner and used microfiber towels. I seem to still get some slight smudging on the glass I can't get rid of. Also because of the weird angle, it's hard to get good leverage to really rub it clean. any tips?

Thank,
Robert

Griot's window cleaner and microfiber towels work well for me. I use the cleaner sparingly (no more than 1 spritz per section). After wiping the section with the damp towel, I turn the towel to a dry section and wipe the residual cleaner off the surface immediately afterward. This helps avoid the streaky look.

Microfiber designed for glass and paint are typically different. The ones for glass are much more flat (like cotton cloth) and less spongy. The glass ones will not haze or streak which I'm guessing is the problem you're having. I use a glass microfiber and Eagle One 20/20 Perfect Vision glass cleaner. Windex in a pinch.
