My husband read so many solutions on removing hard water spots on windows, but nothing ever worked for him. The windshield on our motor home was so stained from the water that would run down it, that we tried everything on the market just like so many others. We bought so many products from acid wash, scrub with SOS, to Comet.
I always use Scrubbing Bubbles for everything in my house. I told my husband for so long to try Scrubbing Bubbles but he always told me, "No that isn't going to work", until one day when he was frantic, he did try Scrubbing Bubbles along with extra fine steel wool. He couldn't believe his eyes. The glass is crystal clear and just like new. Now he won't use anything else just like I won't use any other product except for Scrubbing Bubbles inside.
So every one who is at their worst with hard water spots please use this product. It really does work. I know this sounds like a infomercial, just try for yourself.
Scrubbing Bubbles Fan!

I have had very hard water spots on my windows from the irrigation system for a year. I just tried Colgate Toothpaste as suggested by Chris on ThriftyFun.
I was having trouble getting water spots off my windows until my neighbor suggested using alcohol. I used 91% rubbing alcohol from the drugstore that I already had in the house and paper towels. I didn't even have to scrub. The spots came off like magic.
Bar Keepers Friend and a soft scrub sponge works best for me. It removes all shower spots and window spots from sprinklers. Window on right had the whole lower half with spots.
Use shower cleaner, a green scrubbie pad, and water.
To remove hard water spots from glass, you need glass cooktop cleaner, a non-scratch scrubbing sponge, a wet rag, and a microfiber towel.
My car windows were covered in hard water spots after mistakenly parking near a sprinkler at work on a hot summer day. I have washed my car three times and paid close attention to the windows, but had no luck getting the spots off.
I water my lawn with very hard water in a very windy area. There is almost no way to keep the water off my windows every time I water. In the past, I had used ammonia to wash the windows and vinegar to get rid of the hard water stains.
