Hard Water Spots

Does anyone know how to remove hard water spots off the windshield? THANKS.

I've used Meguiar's Mirror Glaze Cleaner/Polish with good results. Does not scratch. I found it at West Marine but any marine store should have it, possibly a cycle shop too.

a bit of vinegar always worked for me,..tough spots,... leave wet for a few minutes,...to prevent them,...I like the product called THE BLADE by STP,...much better than RainX IMO.......

Thanks for the suggestions! I will give them a try.

My brother - in law shared with me that a large Ranger boat dealer uses Pledge with lemon to polish boats. Used it on my windshield, motor, and fiberglass boat last weekend. Took the hard water spots right off and left a very bright shine which repels water. Worked great!
