i wouldnt worry about it. i am guessing it is fairly cold where you are when you start your car in the morning?
anyway, if it is that much of a pain, take all the belts off, give all the pulleys a good clean with wet and dry (alternator, A/C, power steering and harmonic balancer) clean all betls in warm water and resinstall.
should fix them problem.
if not, change your brand of belt (not all belts are created equal)
