I tried everything to get rid of the squeal including complete replacement of rotors and pads, proper bedding, resetting pads, resin vs metal, cleaning solvents, sanding, baking pads in the oven and using auto brake pad anti-squeal products. Nothing worked. The squeal would always come back.

Eventually I figured it out, switched to plain water and a rag. The squealing has not returned.
