My Yamaha PA cabs are a bit skanked out from four years of regular gigging and the last two years being bounced around and stored the band trailer. Call me fastidious, but don't like shabby-looking stuff; while it is ok from a distance, it ain't very nice looking under the lights. I've already removed all the corners, handles, and other hardware for cleaning up and re-spraying with Rustoleum flat black, and cleaned up all the audio connections. But what about the carpet covering? I can use a beater brush vac and sticky stuff to clean it up, but does anyone have any experience in shaving off the sem-loose fuzzies? I though I heard someone once say a razor blade scraper, to "shave" them, but hopefully some has some practical experience to share??
