No luck with the vinegar. The glass polishing kit does remove a haze from the glass, but these stains just won't go away. Any other ideas?

| Post subject: | Cleaning hard water stains from the windshield |
I recently purchased my sister an off-brand classic car. It had sat outside for a few months and now has some noticeable hard-water stains on the front and rear windshields. They are very pronounced and get worse when I use the wipers in the rain. How do I get them out? I tried a glass polishing kit I bought from autozone, but this doesn't seem to help. Is there any way to remove these water stains from the windows? |

Perhaps its etched; if so...good luck |

Hmmm. I don't think it is etched, it just looks like really REALLY cooked on water stains. Kind of like the spotty residue left on dishes when you take them out of the dishwasher. |

I had something like that months ago..... windshield washer fluid didn't touch it. I think I either used windex or 409 and an old towel....... |

I took some good ol' rubbing compund and a high speed buffer... heat the compound up enough and it will take off most if not all of the water stains.... this is a trick I picked up back in high school when I detailed cars for a living. Just make sure you don't heat the glass too hot... or you will get some discoloration. If you can put your hand on it, and not need to immediately remove it, you are good... if you can't touch it for more than a few seconds, you are getting it too hot. So either use less pressure when buffing, or slow down the buffer. Good luck! ~THOR~ |

Reed My 03 truck has this same water spotting on it. I tried everything. NO LUCK. Went to a Detail shop Nada. They told me it was probally Acid Rain left on the windshield while the truck sat for a month. Its especially bad at night with oncoming traffic glare. If you do find something that works PLEASE let me know. Thanks, Frank |

Will do Frank. So far I have tried a glass polishing kit (pads with abrasives pre-embedded), foaming glass cleaner, steel wool, vinegar, and regular washing and these stains are still there.  Maybe I will try a more expensive/better quality glass polishing system. Mine was $1.99 on sale at Autozone.

This works........... Get some 0000 steel wool, some plastic dish washing gloves, some eye protection, and some CLR cleaner. Get your gloves and face protection on, wet the steel wool with the CLR and rub the stains away. Rinse with a clean terry cloth towel soaked in water. |

Never steel wool on glass; it'll scratch. Use bronze wool if you use any kind of metal wool — and use it really carefully, for it's still very easy to scratch the glass (just ask me about my '62's windshield ). These are scratches that won't show up head on, but when you're driving at an angle into the sun, they'll make your windshield look like it's covered with spider webs.

 Okay, scratch (heh) the steel wool idea.
