After it's nice and clean, a good squirt of Silicone spray will keep it
quiet, too. I know it sounds odd to put lube on a belt but the flat
serpentine belts are different. I've been doing it for years.
The best way I found sofar is using a little steel/copper brush, hold it on
the grooved part of the belt while running idle and clean all dirt off
It will make it go away for a longer time then the squirt on stuff
Offcourse be VERY CAREFUL while doing this
