Just cleaned my bike and used "Greased Lightning" as a degreaser. Great stuff to degrease with but messes up coloration/shininess of components. The anodized aluminum of my Dura-Ace RD has discoloration due to the ingredients of this stuff. I don't care about form as much as function, but damn it! I know products like this state check in an inconspicous area, but damn it. So, if you use "Greased Lightning" on any shiny aluminum beware.
