100LL comes off pretty good with 100LL.
Hey Stewart,For painted surfaces Collinite 840 is hands-down the best cleaner I've ever used. Follow it with their insulator wax and the next cleaning is even easier. For my TK-1s I use LPS 1 or 2. It works pretty well and doesn't leave any visible residue in the nooks and crannies.
Hey Stewart,
Where do you buy Coolinite 840? Can you get it locally here in the Valley?
