You've just washed your car a short time ago, but as it sits in the sunlight, you notice several spots in the finish. These are most likely water spots, which are caused by leftover mineral deposits in the water that was used to wash the car in the first place. Water itself evaporates fairly quickly, but the minerals within the water do not. Have you ever noticed that your car will be spotted up following rain if it is parked outside? In the worst-case scenarios, these minerals can actually get baked into your paint over time; leaving blemishes. Since these are more difficult to remove, the key is to avoid water spots initially.

How is this accomplished? Well, if you use a commercial car wash, pay a couple of extra bucks for an upgrade to a distilled water rinse. While you're at it, make sure that the car wash has an air blower to assist in drying your car right away. Water that is not dried quickly is far more likely to leave spots, even if it the car wash claims that it uses distilled; or mineral-free water. Minerals can still work their way into the distilled water supply as it bounces off of the cars themselves and the dirty floor beneath. Carry a non-abrasive towel in your trunk. As soon as you exit the wash bay, wipe down any remaining wet areas. When you return home, use a damp chamois cloth to remove any remaining spots.

For tougher, stubborn spots, a little muscle is required. Any good car polish should be able to tackle these areas. This will also seal the paint underneath for a period of time which will make minerals harder to adhere to the surface. Products designed to conceal hairline scratches and swirl marks will also work to de-emphasize water stains that seemingly won't come out.

It is rare for something as simple as a water spot to remain a permanent fixture in your car's paint, but it is not impossible. For example, if you live in an area where acid rain occurs, your car will be at a higher risk for paint damage, especially if it is not kept in a garage. The only defense one has at his or her disposal in these settings is frequent polishing and waxing.

Of course, flaws in a car's finish can reach the point of no return. Thus, in these cases, the only option is a paint job. The idea; however, is to minimize the chances of this occurring. The best way to do this is to avoid parking outside as much as possible and to take care of water spots as soon as they become visible.
