How do you get rid of belt squeak?

old trick out of desperation........

liquid soap
around the inner circumference, then work in by fingers to the V
it may slip for a second and won't drive for up to 15 seconds, but after getting through the slipping stage, it will grip very well.

multi-belt transmission is difficult to align for, especially with belts of differing lengths.
look for the belt(s) that may flop or flex a bit more than the others, they are making the other belts take the load

I would still like to find a matched set of belts before going on to some thing else . I would check the pulleys to make sure nothing is off
 
Switching from Dayco to Goodyear belts solved a persistent belt squeak for me.
It seems that Goodyear belts have been rebranded to Continental Elite as stated on the following page.

We have two compressors at work, they both have four belt sheaves, there is always one or two that flop. Matched belts should make a comeback
 
I worked in industrial environments for many years and worked with many V-belt drives. I had very good success using banded v-belts on multi-belt systems. I started using these even back in the days when you could buy matched sets and they were always superior to the matched sets. They aren't cheap, but I found that they also lasted much longer than individual belts.

I don't wear mine in the shop. I still can hear enough to prevent a problem.
 
Belt dressing is a temporary fix don't waist your time and money. check your alignment. and the condition of the sheaves. New belts should ride about 1/16" above good sheaves. make sure the sheaves are not polished. that just causes more squeak. Take a bit of emery cloth and rough up the sheave, this will increase the friction and allow the belt to grab. If a new belt rides below the circumference of the sheave change the sheave
 
We only used it at the auto repair shop as a diagnostic tool. A light spritz ruled out belt squeek if that was the problem. After pointing out the fix was only temporary, the customer often had a new belt put on.
 
You say "squeak, squeak" as in something is not running true or concentric as opposed to continuous squeal under load as in poor design (too small sheaves for HP or something like that). Might take a closer look to correctly diagnose the problem.
My 2 cents

When I was an automotive tech we used light silicone spray to quiet belts but never belt dressing
