squeaky belts

After removing the belt, rough the pulleys up with a wire brush to remove buildup in the groves and to remove any polishing. I know of one guy who claimed he could not get his to stop squealing no matter what... New belts, new tensioner, he roughed up the pulleys with a wire brush,.. he eventually resorted to painting his pulleys with a bit of muriatic acid into all the grooves and letting it sit on them for an hour or so, washed it off with plain water, then wire brush again, -- After that, no more squeal.

Thanks Rawze and you're right the pulleys are quite polished so I will try your suggestions
