Replaced the belt with a continental belt from Fastlane. Within a couple of weeks, a squeak developed. The chirp coincided with the yellow lettering on the belt. I removed it and spun the alternator, water pump, etc. and couldn't seem to get a squeak. I put the old belt back on and the squeak was gone. Examining the new belt that I just removed, I noticed some dust on the ribbed side sort of like brake dust. With what could someone clean a serpantine belt? I was thinking about dish soap and a tooth brush. Anyone else have this problem?
