Hard water stains on windows

[PeppeX]

I got some hard water stain on my window. Tried autoglym glass polish and it didn't really work. Do you guys know how I can get it out?

I been researching and some say Spot-X hard water stain remover works but I don't know where i can get it in Australia.

Worst comes to worst probably need a professional to polish the windows. Any place you guys recommend? I am located in Sydney.

have you just tried washing the car with good car wash detergents and warm water and after that using some windex with some newspaper?

and are you sure its from the outside?

i just use windex an it usually fine

[PeppeX]

I've tried clay bar, doesnt work. I've used meguiars NXT.

So i spray windex then wipe off with newspaper?

[simmy]

yeah give windex a go,,, and wipe it off with newspaper repeat steps if water stains still occur

[PeppeX]

Don't have 'windex' at home, but i have some random glass cleaner but it doesnt work.

get some gumption, and the finest steel wool you can find.

smash repair shops use steel wool... ive always used clay with good results

[PeppeX]

Want to avoid steel wool as it can scratch the windows.

I think the clay I have is very fine so can't really get the stains out.

Autoglym glass polish works but takes a very long time and ALOT of elbow grease so i kinda gave up.

I've got the same problem, I've tried using my polisher with a wool pad and autoglym glass polish. I've also tried a clay bar.
Sadly to no avail.

+1 for gumption

look for it in supermarkets or hardware

I had a very similar problem and had good success with "Reflections" metal polish on a set of felt pads (4 x 3" diam mounted on a 1/4" bolt in a drill chuck). I thinly smeared the polish by hand over an area about the size of a footy and then buffed it with the felt pads.
