If it seems that the CLR PRO Hard Water Stain Remover did not help at all, the glass may be etched and there is no remedy to remove the cloudiness. The cloudiness is actually tiny cuts made in the glass by deposits in the water. The only thing that may remove the etching is a jeweler’s polish. Once polished to the original condition, use Hard Water Stain Remover for regular maintenance to prevent etching from occurring.
