the water spots are made from lawn sprinklers that spray on the car and then dry. I think the white spots are mineral marks. But I am also trying to remove them.

That response is clearly wrong. Water spots will indeed grab hold of the glass in the microscopic crevices ("pores") and seem like they are embedded in the glass. This is seen when you pour water on 'perfectly' clean glass - the water will sheet, as apposed to beading. Sometimes light polishing alone won't do it.
There are multiple techniques.
First, vinegar and a sponge or wash mitt, only on the glass.
Second, tape off the trim around the windows and use a polishing machine and apply glass stripper compound.
Otherwise, tape off the trim around the windows and use a high speed rotary polisher with some compound such as "Menzerna Powergloss compound" then follow up with a much finer polish (the other steps in reverse order from this one) to remove any holograms, marring, or swirl-marks that you will create with the heavy compound and such a heavy duty machine.
Lastly, always follow-up with a coat of rain-x on the glass. Not only does this repel water, it fills in the microscopic "pores" in the glass, which seals out the water with deposits from being able to embed when drying.
Usually it doesn't take this much effort, but sometimes the cases get this bad...
