Hi Scotty and all car enthusiastic peoples!!
I have Corolla 08 brought from neighbor for very good deal, however the windshield area which couldn't reach by wiper blades have serious ammount of rain watermark and some on rear windows too. The effects not obstructed my daily drive but can't help to notice it everyday.
I try clean it with alcohol + water, vinegar, windshield polish but it couldn't remove it. I want to use product contain acid but some people review say it ruined their windshield!
Any advice for me to try remove these marks or just live with?
These are hard water stains. Hope the following link helps:

I don't know what kind of water mark you mean. Can you post a photo please?
Sorry, I don't know how to attach image from my phone. But here is my picture link: https://ibb.co/vmT8Try
I realized the correct term for my problem is "water spot".
That looks like dried on salt residue. Wash it with a bucket of hot, soapy water and a scrubby sponge or brush. Rinse with lots of water.
Which windshield polish did you use?
Is Autoglym Glass Polish from Amazon UK. Initial I want to get Meguiar's Glass Polishing, but I can't find it at my regions.
Right, I use Meguiar’s and it always works for me. I don’t have experience with Autoglym.
have you tried NU FINISH CAR POLISH in the orange container? Scotty recommends it and it makes my 40 year old glass nearly like new.
