Hard water spots....<br /><br />I think they're etched in the glass.<br /><br />I've tried everything. What now?<br /><br />Is there a cleaning compound like a deep cleaning wax for glass?<br /><br />I vaguely remember asking a glass shop about this, and I think he said 'Pumice' paste.<br /><br />Has anyone tried this?<br /><br />H.
