Do the belts appear to be glazed or have a brittle look where they contact the pulleys?
I have improved squealers by (verrry carefully) holding a sanding block against the surfaces of a moving belt to roughen the surface a bit.
If you do this (and I am not suggesting anyone should) think about where your fingers are, where that block will go if it gets launched and don't induldge in any distractions.
Only takes a couple of seconds to change the characteristics of the belt surface.

Did anything change just before they started squealing? I replaced an alternator once with a rebuilt unit that had been supplied with the wrong diameter pulley; and it's belt would squeal like crazy on cold mornings. With the smaller pulley, the belt just couldn't handle the load.
Another problem worth checking for, I have seen belts wear until they ride on the bottom of the pulley slot, instead of the sides. A new belt is the only solution.
Belt dressings will help sometimes, but generally are only a short-term solution.
