Personal experience using:
Dawn Dish Soap - VERY good grease cutter. Removes wax.
Simple Green - Excellent product, paint and plastic friendly. Can use undiluted.
WD-40 - Heck of a grease cutter. Do not get it on brake parts.
Tail of the Dragon at Deal's Gap... Avoid it now, do a trackday.
Do not do business with Myrtle West Cycle... Not a reputable vendor by a long shot.
