how do you remove hard water stain on my windows when Windex doesn't work?

White vinegar has been proven to work for removing hard water stains from windows. See the step-by-step method below:

Natural Formula to Use:

½ liter white vinegar and ¼ liter of water

Method to Use:

1.Fill a clean spray bottle with pure vinegar

2.Spray the vinegar/water solution over the window and wait for a few minutes

3.If stains are stubborn spray more solution and wait a while longer

4.Scrub lightly with a soft sponge or cloth and rinse

Tip:

Try to deal with the water spots straight away as the solution works best with newly formed or mild hard water spots.

Use white vinegar and water, a 2:1 solution. Check out the YouTube video link for a 2 minute demo. Works for chrome or glass. You'll only need to do it once, just follow the video instructions.

Little bit of white vinegar on a soft cloth will take the spots off and not leave any residue. The residue is calcium in hard water, a mild acid like vinegar will take the calcium off and not harm your glass.

This is really tough. you need to use a vinegar solution. vinegar is acidic and hard water is base (opposite ends of the ph chart, and it will probably take several washings

Try this its cheap, clean them again with windex but use newspaper.

All i can say is try using boiled water, other than that somethings just wrong with your cleaning liquid, get your money back!

RainX makes a cleaner to remove everything from glass and it works really well!

rub the glass down with 000 steel wool from the hardware store, if it's going to come off it will take it off.

some stains are actually etched into the glass - from acid - and you cannot remopve them. too bad.

matt was close- use dry crumpled news paper.
