Softeners, on the other hand are simply used to remove calcium, which can be a large part of what makes hard water. Softeners basically convert calcium and magnesium , to sodium or potassium which should spot a lot less.

These units typically last a lot longer, and are a great solution for getting your glassware shiny again, reducing water spots on shower doors, etc. If you want the added benefits softened water can have throughout your plumbing indoors, this may be the best solution.

So you have done everything you can think of and you still have water spots, what now? We are going to cover a few methods from least to most aggressive . The first thing you will want to do is simply either wash the vehicle in the shade, early in the morning, or evening. Making sure to dry the car thoroughly after washing. If you have a pretty clean car you could try to use a quick detailer with a microfiber towel instead of washing. If the water spots are still there after washing then you need to get a little more aggressive. The next thing I would try is a 50/50 mixture of distilled water and regular white vinegar. The vinegar breaks down the minerals in the water spots and makes them easier to remove. I normally choose to spray my towel a few times and then gently rub on the spots till they disappear, its best to do this on cool paint. I will then clean the area with either a quick detailer or wash the area to remove the vinegar from the paint. Most of the time washing or the vinegar solution will do the trick. But if both of these fail, then you need to move on to the clay bar. Using the quick detailer to wet the paint use the clay bar and glide it over the water spots to see if the clay will pick up the above surface mineral deposits.

I first located a small inconspicuous, area in the bottom corner of my windshield, by the wiper. As advised, I wet the steel wool with water and made little circular motions, with a very light touch and dried with a paper towel. The glass in that area was black.

They were completely gone everywhere else!

But I wasnt ready to really go for it, on the more visible areas, just yet. I next tried this on a small area of chrome molding, next to the windshield. Also, with a light touch. Success again!

Therefore, dilute it in water and dab some on a microfiber cloth and then wipe on the glass. Dont be very generous with the solution as it may spill and etch through paint.

Rub the CLR and water mixture on the car windows until the entire surface is covered. Let it sit for a minute. Clean off the residue gently and then rinse it off with water.

The next progression for removing water spots is with a clay bar treatment. Commonly referred to as claying, this approach utilizes a synthetic, putty-like bar, or a hybridized mitt or cloth to remove contaminants from a vehicles exterior surfaces. Claying should only be attempted after the two-bucket washing method and white vinegar wipe-down prove to be ineffective.

Required Car Claying Supplies

  • Bottle of claying lubricant
  • Clay bar/mitt/towel
  • Microfiber towels for drying and hand polishing

Lube-up Your Automobile

After spraying the entire vehicle down with water, apply some lubricant spray solution directly to the section of the vehicle that you plan on claying. Applying some lube on the clay tool you plan on using is never a bad idea either, as it will make the contaminant removal process all the smoother.

Clay It Like You Mean It

Once you got her all lubed-up, rub the clay bar in a back-and-forth motion, always following the lines of the vehicle. Regardless as to whether you have selected a bar, mitt, or cloth, all automotive claying products are designed to contour to the surface of the vehicle, so try and hit every square centimeter of surface area. Just make sure that you NEVER clay in a circular method, for this can damage the clear coat.
