Any thoughts of getting water stains off front windsheild? Plenty glass cleaner and washing didn't help. Someone suggested wax

 

Water and vinegar solution will dissolve hard water deposits, but I don't like the idea of using an acid on my car.
I have seen detail shops use 0000 steel wool to clean windshields, no It doesn't scratch it. But then you're left with little pieces of steel wool that will rust and leave stains wherever it lies.
Clay bars are awesome for cleaning glass sparkling clean with zero drawbacks. It even polished out some fine scratches in mine. IDK how, but I'm not looking a gift horse in the mouth.

 

Could try a dual orbital polished of the Palm sized variety with a polish. Might be worth a try.

I've used Duragloss for years and it always does the trick. If your comfortable with a buffer, poor it on the glass, spread it out with the pad and buff as if you were buffing paint (side to side, pad flat on surface). Comes out looking like new every time. Just make sure you mask your weatherstripping with tape about a half inch from the edge of the glass. Once you get the majority of the glass done, remove the tape and do the edges by hand.

 

this is a stuff called Spot Not. takes it off every thing. in just secs.

wash your car like always.. keeping it wet..(the glass) appply to wet glass with sponge wiping glass. give it 30 sec no more.. and spray off

gass is like new...(not joking)

 

Duragloss 501.... May be available @ local CarQuest. Its a great chemical cleaner. Works well on removing oxidation off of metal with steel wool.

 

brand new steel wool 0000 with some polish that has light cutting. Don't use old wool as the rust will scratch the glass as the other person said.

 

Hello CAMAROKR @ Dyess A.F.B. in TX.... What do they use to clean the W/S on the jets ?
