Hard Water Stains

Around 4 days ago my car was caught in my neighbors sprinklers. Unfortunately the water dried and my car was left with some hard water marks. Today I washed the car and tried to remove the marks, but unfortunately even after washing, and then treating the area with P21 Gloss Enhancing Paintwork Cleanser, the marks remained. I even tried claying the area, but the marks remain. I finally tried Meguiars Scratch X 2.0. After 2 separate attempts, it partially removed the stains but a few still remain.

I'm at a loss here. What other products should I try treating the area with?

I'm really at a loss here. I regularly clay, wash and wax my car. I use hardwax every few months and for every wash in between, I use some type of spray wax/quick detailer. My paint feels like glass. I don't get how the calcium in this water could penetrate the paint.

You tube Adams detailing and Griots Garage.... I know I have seen something for hard water stains. I would check the detailing section on M3forum.net as well

I did some research and discovered vinegar and water works to remove hard water stains. I laid a towel soaked with 50/50 water/vinegar on the problem area for 7 minutes to let it fully penetrate. Afterwords, I dried the area and hit it with scratch x two more times. No more spots. After that I threw 2 coats of P21S hard wax over the whole area and it looks great.

/Water doesn’t leave marks or etch surfaces; it’s the minerals that it contains calcium (Ca) and magnesium (Mg) and reactivity (heat acting as a catalyst) the spots are actually traces of minerals left on the surface when the water evaporates. Alternatively they can be caused by industrial pollution (i.e. acid rain, bird excrement or industrial fallout)

Generally surface water-spots have no raised edges and are very shallow and so cannot be felt, they are very similar to micro-fine surface marring. They cannot be removed from the surface by washing but they can usually be removed with a 1:1solution of vinegar and distilled water; this acid-based (acetic acid) formula breaks the bond between mineral deposits and the vehicle surface. For minor surface etching use a slightly abrasive chemical paint cleaner


Note: Vinegar is a liquid produced from the fermentation of ethanol in a process that yields its key ingredient, Acetic (Ethanoic) acid, pH 2.7
