Blew an upper radiator hose and soaked the belt with antifreeze, and now the belt squeals. I can spray the belt with belt dressing and it will help for a little while, but the squeal comes right back. Any cheap options before I buy a new belt?

 

You could try using dawn dish soap and hot water. That's what I did when I had a hose go and shoot coolant on mine. I knew that if I didn't, the belt would be toast. So far, not a problem.

You may take the belt off and put it in a bucket with hot water and soap and give it a good scrubbing by hand and then let it dry.

 

Thanks, will try

 

Try cleaning all the pulleys. The belt probably spread the leaked coolant onto the pulleys.
