I have a lot of hard water spotting on my windows. I've watched a few videos on line and most of them just look like they're trying to sell their product.
I would prefer an opinion from someone who has had this problem and fixed it. Thanks for any help.

 

Have you tried vinager.

 

I've tried vinegar, spray way glass cleaner and a couple of other things. Thanks for your suggestion.

 

0000 steel wool. Try an inconspicuous spot first if it makes you nervous.

 

I have used CLR to dissolve hard water stains and build up on plumbing fixtures, kettles, etc. Also use on shower glass doors.
Water is very hard here so we have a water softener unit also.
Try in a small spot first of course. And of course in future use that chamois to get the windows dry after washing.

Another solution to the spotting issue on your glass is a clay bar with detail spray. Don't buy the traditional "clay" type bar, but the reusable Mothers that can be washed and reused numerous times. This will work on your paint as well.
Just my 2 cents....

Thanks for the suggestions. I will try them. Hopefully something will work.

The water spots have been on the car since before I bought it in April. When I wash a car I always dry it immediately. I've never had any spots like these.

 

Water spot update;
I've tried vinegar, steel wool and a couple of other things. I even tried this "Heavy Duty"Water Spot Remover. I tried 3 times with this and it didn't work.
Next is the clay bar. If that doesn't work, I guess I'll have to find someone who polishes windshields.

 

Acid rain in some areas close to heavy industry can etch glass. I parked a car of mine outside of Sudbury, Ontario for three days and it etched the glass and the paint. The glass was not too bad but the paint was a mess. Inco the polluter, paid for repairs, being a visitor to the area I knew nothing about this though. The area around Sudbury looked like the Moon, there was no plant life, it slowly got greener as you moved away from Sudbury. Their solution was to build a taller smokestack among other changes.

That's terrible! I'm glad that they paid for the repairs. Hopefully they will come up with a real solution to solve the problem.

 

Update;
I will try a few things in the next few days or so. I will update as soon as I get the water spots removed. Thanks everyone.

 

UPDATE:
I ended up using Griots' Garage Complete Compound on a 3 inch pad attached to a drill as was suggested too me.
This worked very well and didn't take that long. I still have to do some areas by hand on the lower part of the windshield because I didn't want to damage the wiper arms or seal with the drill.
I did the side glass as well and in one of the pictures I did a 50/50 before and after.
Another suggestion was made to use shop towels soaked in vinegar and lay them on the windshield. I wanted to try that method but the towels have to be kept wet and would require spraying them every few hours with more vinegar too keep them wet.
This may have worked and would have been the most cost efficient method. Because I am caring for my father I didn't have the time to try this method.
I thank you all for the help and great suggestions!



This what it looked like originally.

Another picture after multiple attempts of different methods.

After using polishing compound. Still needs some touch ups by hand. Inside glass needs to be cleaned with glass cleaner.

The white spots are the "sling" from the compound coming off of the pad. It looks so much better than before!

50/50 of the driver's side window. What a difference!

This is the compound that I used. It was about $13.00 on amazon.
