Best way to erase hard water stains?

 Hi all,


although this doesn't apply to my boat (more so a recently acquired, old school subi) I was wondering if anyone knows any sure fire ways of removing hard water stains from glass? No doubt there are fisho's on here that have had the same issue with their boat screens? I've tried vinegar, car polish applied by hand, wd40, steel wool, simple green glass cleaner, even bloody carby  cleaner!


any detailing or glass guru's, the suggestions would be appreciated. It's for the rear screen but as mentioned I'm sure others have faced the same battle with their boat glass?

 Nice car, I had a 99model then a 2005 model. Great fun.

it's surprising to hear that 0000 steel wool soap pads won't get it off, that's always worked for me. Have you tried a

mild abrasive like toothpaste?

look up Shannon lush, she used to do a cleaning segment on 6pr and is a guru on anything cleaning. Pretty sure she has a website.
