In an attempt to become enviro-friendly, I purchased a bottle of citrus scented degreaser which I mixed with water as per instructions. In rebuilding my son's Dura-Ace headset, I left the parts to soak overnite (entirely safe with paint thinner) only to find that the chrome on the the top race and fixing nut was no more. Anybody else with this experience? So glad I did not learn this lesson with Campy parts. Rod Handsfield, Las Vegas 76 degrees.
