I have used Kaboom in the purple can, on the shower doors in my home, and it has cleaned them very well, took the scaling and water spots off the doors. It's worth a try.

Good luck.

Straight White Vinegar, a rag and lot's of elbow grease. Put it in a spray bottle and soak it down a few times and let it sit before scrubbing.
I have extremely hard water pumped right out of a creek here and am always scrubbing off the spots. Hopefully this summer we sink a well which might take care of it.

Try the original Bon-Ami. General Motors recommended that for years. Don't use the newer type. I bought mine from Amazon.

There is a glass windshield cleaning video that shows using the FINEST steel wool you can find and in circular motions cleaning your windshield. Takes all the stuff off that gets stuck there.

I tried this after being under a tree that left crap all over my windows and couldn't get them clean. Worked great! Just used the FINEST steel wool I could find and went gently over the window and then washed the car all over and then treated the window with Rain-X.

Then used this procedure on all windows on both the car and MH and then shine like crazy and no longer look dirty no matter what I do.

Give it a try.

I use 0000 steel wool to clean my windshield regularly. I don't know about hard water spots but you might give that a try.

Phosphoric Acid will take the water spots right off.
Fuller used to sell it for that purpose and general cleaning of sink/tub fixtures.
Use it like CLR and several others keeping it off paint, marble, wood etc.
I use a wet sponge and wipe the window then apply Phosphoric Acid to the sponge
and apply to window in a circle scrubbing then wipe clean with a damp paper towel then rinse with plain water and dry.

Just about any hardware store, Walmart, Home Depot and the such will have it.

I put my sprinkler (well water) to close to my truck and being sprayed for a few hours it turned everything white. Took it to the car wash twice and didn't help much. Had a day of rain and it all washed away.
