Thank God for the Search feature!
My serpentine belt noise was driving me crazy. I tried spraying WD40 and Windex that made it go away for a few seconds but nothing like Comet! After doing a search that hinted on Ajax, I tried sprinkling Comet on a plastic teaspoon and on to the idler pulley with the engine running and the chirping disappeared like magic. I even took it on a 15min test drive and still no noise.
