At some point, I'll probably attack the smooth parts of the cases with some aluminum polish, but for now, q quick, medium pressure soda blast will clean everything up and get it ready for whatever level of heck you want to put yourself through....

Pressure wash the gunk.........Soda blast. (I use harbor freight with good results works wonders on the carbs too) .........Polish.......hand and with air wheel. been there done that. unfortunately there is no magical spray
