How do you take hard water off windows?

I would try white vinegar, spray it on there and let is sit awhile before scrubbing off.

vinegar mixed with water works miracles

If the vinegar isn’t getting it all, you could take a single edged razor blade and judiciously hold it at a low angle and scrape them.

I would try lemon essential oil

Vinegar usually works on my windows, we have very hard water! Try to let it sit, it's hard because it wants to run. I wet the window, then place paper towels on it and spray them down to try to keep the vinegar from just running off.

I agree that vinegar will probably do the trick! If you heat the vinegar for a few seconds in the microwave, that should help, too.

Hi Polita,

Try a little vinegar on a cloth along with a spot of w/up liquid too..

Here is a nice video tutorial for you: https://www.youtube.com/watch?v=saGAHGTSEug

Use a single edge razor blade, using a scraper attachment they sell in the hardware section at the big box stores. Everything including paint comes oft

Here's a post that might help - https://www.wikihow.com/Clean-Hard-Water-Spots-Off-Windows

Believe it or not I used oven cleaner from the dollar store. It has ammonia in it and easy to spray. Then I just washed the windows down with a hose.

CLR would probably do the trick.

CLR applied full strength. It can be purchased at WallMart, etc. It's in a green bottle and is clear like water.
