What do you all use to clean the drive chain? The book recommends kerosene, but it's hard to find here. I tried "purple power" degreaser from discount autoparts and after soaking in it for 10 min the old grease was "mostly" disolved, but there were still some chunks here and there. I do use Maxima Chain Wax which may be part of the problem (does anyone know if this stuff disolves well in degreaser?). Are there any recommendations for something better?
