I know that this is kinda expensive, but I have just started using Coleman Lantern Fuel.....WORKS GREAT...........INCREDIBLE....Originally I started to use the good ol handy Windex or some kind of window cleaner with some paper towels.....Bt then I found that the paper towels would make very small scratches, and I didn't like that; plus, the windex will not cut the grease/fuel residue...!!......Well anyways......the most recent time that I just crashed my plane.......I was cleaning it and my dad suggested using that fuel and it does GREAT......VERY GREAT......I am thinking of mixing that fuel with some alchol, water, and then some 409....THAT WILL WORK EVEN BETTER than anything that I've found.....Haven't used it yet...but I'm sure that it will work fine.....


P.S. I wouldn't use that fuel on a regular basis....IT"S EXPENSIVE like I said....
