I have a car with "hard-water" stains on the exterior of all windows. Windex Glass Cleaner is not effective.

Question

Can you recommend a product that will remove the stains without damaging the car windows or body in the process?

I only need to remove the stains from the OUTSIDE or EXTERIOR of the windows. Not the inside.

Answer 1

C.L.R. is great for hard water spots on glass shower doors. I'd try it.

Answer 2

I'm not sure about whether this would damage your car's finish, but I use Comet Bathroom Spray Cleaner to get rid of all hard water and mineral build ups. Its very effective and inexpensive. You would, of course, probably have to wash your windows afterward because they probably won't be clear if you use this stuff. You may or may not have to let it wait for - like - 20 minutes.

Answer 3

Use white vinegar and water, a 2:one million answer. look into the YouTube video link for a 2 minute demo. Works for chrome or glass. you will purely could do it as quickly as, in basic terms save on with the video training.

Answer 4

Serioulsy before you try ANY of the others advice, please try this.... use a little bit of cleaner wax, like turtle wax or something. It will take it right off. Comet is grainy and will scratch your glass. CLR may work however I wouldn't want to risk dripping it on any of the paint or plastic parts.

Answer 5
