Have you tried Nevr Dul?bigboi18184 said:Don't get any finger prints on them missed two small finger prints on first install and they burnt on and will not come off. After they heat up the first time I haven't noticed any more burnt on finger prints and I have forgotten a few on it since then. Mine are the chrome version though don't know about the black, clean mine with a damp rag (water only).......clean whole bike like this to think of it.
