Trick for removing hard water spots.


Recommended Posts

Having lived in areas with very hard water, I can tell you that the marks left behind by the calcium deposits can be very annoying, especially on dark colored cars. I just learned an easy way to remove these spots before waxing. I used a pad of several layers of paper towel saturated with plain old white vinegar. It works like a breeze. I keep a terry towel with me and do about a panel at a time, wiping the vinegar off after letting it set for just a few seconds. After the wipe down, I either use a spray wax or a paste to make the car look like new again! Make sure the car is clean and cool to the touch. I'd recommend doing it in the shade as well to avoid streaks.

I've tried to remove these marks in the past with polishing wax or scratch remover, and even though it works, it's a LOT of hard work. Using the vinegar is so easy you won't believe it!

Never underestimate the amount of a persons greed.

Thank you, I am going to try it on windshields also!

I have used a little CLR on my car finishes. Just pour a little on a wet washcloth, and wipe down a cool already wet car.  When you rinse with a hose,  you will see the clr foam up a little, and get sudsy.  I have also wiped my wet cars down with a little dish washer rinse aid (jet dry).  I know both products say not to use on cars, and are not endorsed for such a use, but wow, sometimes the chalky stains creep up on a car, and after they are cleaned up of this stuff, they shine.  They will probably need a good waxing after this. Make sure to dry the cars after this wash. I also dry with my air compressor spray nozzle to get in the crevaces.

It works great on windshields Mike, as well as all glass surfaces. In fact, glass is the easiest place to tell just how well it's working since the stains are much more visible on tinted glass.

As far as the CLR goes, it seems a bit harsh. Maybe not so much on the car's finish, but I don't like that stuff on my hands. It's also quite a bit more expensive. The vinegar is cheap and most people have a little bit laying around the house.

I've never tried mixing it with the wash water, but that might be an option. Maybe even in one of those hose end sprayers for the final rinse would work.

That is great to know Johnny, I have problems with water stains on windows, and Ill bet if I look close enough also on the paint.  Thanks, good info.
