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.
I have four 10'X6' windows (all glass) and about 15 smaller windows of different sizes that get sprayed by water containing calcium, and various other minerals that will not wash off with soap or other washer solutions. I presently use dish soap and hot water and a bit of CLR added. I have used an ammonia solution, vinegar, and rubbing alcohol. Nothing really phases the stains even though the windows get clean, they still show those hard water stains.
We use ditch water to irrigate the lawn by a sprinkler system. Help! I also used automotive products and the products that you are supposed to put on and hose off. They definitely made no difference other than to clean.

I just got done cleaning 2 small windows. Like many of you, they had years of calcium water spots on them. You could barely see through them. I used the Barkeeper's friend and it worked. I made it into a paste on a small scrubber that you would use for pots and pans (non-abrasive). I finished it off with WD 40 and now the windows are shiny and look like new. It was a fluke that I tried it but I had tried everything else that was on the internet... I was at my wit's end. I tried all of the other suggestions and this one worked!
All my windows have spots on them and that makes it difficult to see. I have deep, deep water. I have tried many cleaners. Please help.
I use a squeegee to clean my windows, no water left on them to spot. Would that solve your problem? I just use Dawn or Mr. Clean in the water, and clean the outside windows with a long handled squeegee, such as you use for washing car windows. I have one with an expandable handle to reach my windows that are on the upper level.
If you can take the windows off the track and get them on a level surface, then use the thick Lime Away on the windows, letting it sit for about 10 minutes, not touching the aluminum sides, then this should take care of your problem. You may also need to use a green scrubber, like what some use for pots and pans. Please try to protect your hands while using this and try not to breathe any fumes from this product.
A scratchy and a rag with clear vinegar will do the trick.
If you have hard water spots on your windows they will be hard to clean. Lime away does work but I don't like the harsh chemical. Spray your window with a window cleaner and use a scraper with a blade (the kind you use to remove paint on a window) to scrape over the hard water spots.
DO NOT use a scraper blade on double glazed windows as the glass is softened as it heated in manufacturing and the blade will scratch the glass - trust me I did it
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 had washed my car in the afternoon and the water drops dried. I was unable to remove the stains. So how can I remove the stains? My car is a Maruti Suzuki swift.
Sorry, plain vinegar DOES NOT WORK, I'm a professional window washer, for 15 years, deep water spots won't go away, only if it is on the surface and is new, then Lime Away and a paint scraper will work.
I've tried to clean my house windows with cleaners such as Windex, Bon Ami, vinegar, Colgate toothpaste, Cascade, Dawn, and baking soda. They are stained with water spots and grime. We live on the golf course and I don't know what all they spray on the fairway, etc., but I can't get my windows clean. Please help!

Try a Magic Eraser on one, and you may be able to get the build-up off. You will probably need to follow up with Windex or another glass cleaner, but hopefully they will do the trick.
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.
How do I remove hard water spots from glass?

Vinegar or CLR.
How do I get water spots off the outside of a picture window?
Are they water spots caused by hard water, such as that from a sprinkler, hitting your window? If so, vinegar should remove them. Do not dilute when you use it. I would put it in sprayer, and spray on full strength.
To remove hard water spots from glass, you need glass cooktop cleaner, a non-scratch scrubbing sponge, a wet rag, and a microfiber towel.
