My brand spanking new 1260 S GT suffered a little after a long trip to the UK last year, I didn't rust protect it before hand and I left it a few days after my return to wash it. As a result, the shiny cable nipples or what ever they are called are no longer shiny and rough to the touch. Is there an easy way to clean these up? Maybe some sandpaper and love? Or am I just going to have to replace them down the line?
