Default Removing hard water stains from front windshield?

I had a sprinkler head break and couldnít replace for a few days. While broken, it sprayed water onto my truck. Now I have hard water stains on the windshield and canít get them off. Tried Mr. Clean Magic Eraser and 1/2 lemon with Kosher salt. Both did nothing. Anyone know any secrets?

I had the same problem white vinegar wouldn’t cut it so I stepped it up to toiled bowl cleaner and it worked like a charm

Ill try white vinegar first, but if that doesnít work, did you just put the toilet cleaner on a rag?

Yep full strength but sprayed it off 30 secs or so after application. I tried everything to get the stains off and this is the only thing I found to work

that was my next step if the bowl cleaner didnít work. I keep a spray bottle full for general rust stain cleaning around the house but thought it might be a little harsh on my vehicle

This.

I do this all the time on motor homes I detail. I use a light compound with the 0000 wool. Then polish it out afterwards.

I have had to use an acid on some of the worst ones but I keep a wet towel handy and wet the glass prior to applying the acid. donít let it set long before wiping it back off with another wet towel. It may take a few times depending on how bad the spots are.

This does work extremely well. One thing that steel wool can do is leave tiny pieces of steel that can rust and leave stains. If you can find it easily, 0000 bronze wool works just as well, but will not leave little pieces of steel to rust. If you rinse/ wash the heck out of it after, it probably doesn't matter but the wool does an incredible job of cleaning the glass.

Fastest thing I found was a buffer and 3m rubbing compound. I havenít used it on my windshield but I do use it for my glass shower door and dividers. Iíve tried some of the above methods as well.

Yet another 0000 steel wool recommendation. Do it once a year. The windshield will look great and you wipers will work better. Not only will it take the spots off, but all the other crud that is there too. Blow off with compressed air afterward. If you want to get crazy, clay bar it after using steel wool then out a ceramic coating on it.

Normally vinegar mixed 50/50 with distilled water will take it off.

Lime a way gel. Apply with paper towel. Repeat then windex it. The acid in it breaks down the calcium compounds. Works great on boats also.
