Over the last few years l have been distracted on other projects, namely, renovating classic bmx bikes, a trick l came across with bringing chrome to life, basically, scrunch tin foil up and dip it in white vinegar and gently rub, l was amazed at how well this works. Anyway, if it works on handlebars it may work on all chrome, below is a picture of a bmx l picked up that had a pebble dash of surface rust and oxidization, the bmx is a 1999 Haro Dave Mirra 540 Air, and yes l still ride them at the tender age of 53, get some strange looks
