For glow fuel I like to use Fast Orange cleaner or 91% alcohol since I always have it with me for my gas engines. Both work really well for me. I hear that simple green is good too. Windex works ok too it just cuts the oil a little more slowly so it takes a few more wipes.

On glow and gasoline, like Bubbagates I also use alcohol but I use 91% alcohol from Walgreens, but for some reason I don't get the sense that it works quite as well as fast orange, but that might just be me. 91% is about the same price as 70% rubbing alcohol but it cuts a lot better. The exhaust residue from a gasoline engine can be like road tar and alcohol cuts it like butter with a hot knife.
