Don't use the belt dressing.   Spray it down with silicone lube, or 
maybe some Black Magic vinyl/rubber treatment.  The belt dressing 
(depending on  brand) is probably what's making it squeak, especially 
if there are some deep pulleys along the way.  The silicon lube or 
Black Magic won't make the belt greasy enough to actually slip during 
normal running.   It does keep the belt from squeaking as it feeds 
into and out of the pulleys.

One of the old tricks to stop belts from squeaking was to rub them 
down with a bar of soap, just brush the bar against the contact 
surfaces of the belt with the engine running until it stops squeaking.
