My mid-60's Selmer MKVI was de-lacquered many years ago. Over those years, the horn has become duller and grungier, and I'm trying to get it back. I'm taking keys off a few at a time (working on the bottom bow, right now), and polishing with Parker & Bailey Brass Polish, Brasso, and Wright's Brass Polish. I'm using Q-tips and strips of cloth to get around and between tone holes and posts (and jabbing myself with springs). The Wright's seems to work fastest, but still requires LOTS of rubbing. Does someone have experience with a brass cleaner that, like, melts the tarnish away almost immediately? Or, at least more quickly than the stuff I'm using? I've done this before, though it wasn't in quite such bad shape, and it was beautiful! But, it doesn't last, and I don't want to dot his again. How might I maintain the shine other than a re-lacquer? Is there a spray clear-coat that I could apply that would last and doesn't look cheap? What about car wax? I sort of regret the night that my band mates (one of whom is a Selmer-trained technician) got bleary-eyed over a bottle of jack and decided to remove all the ugly, worn lacquer on my horn. It's never been mechanically buffed, and I love the warm look of the raw brass ... but this cleaning business is really time-consuming (when I could be practicing!). So, please, any ideas on a more efficient cleaner, and ways to preserve the resulting shine?
