How To Wash A Black Car Without Water Spots

Car colors are mainly hit-or-miss, but one true color never goes out of style: black. Unfortunately, it’s so appealing that even dust particles want to participate. Unlike the other colors of the rainbow, black attracts dirt like a magnet.

Washing a black automobile may be difficult since water stains might appear. They are caused by pollutants that are left behind when the water in the vehicle evaporates. They can detract from the appearance of your automobile and, worse, corrode or harm the paint.

To avoid such issues, you should learn how to wash a black car without water spots. This article will teach you that and more than that!

What Causes Water Spots On Black-Painted Cars?

Water stains are one of the most prevalent factors that make automobile finishes seem unkempt and unattractive. They are primarily due to three factors that we will mention below.

We’d explain how these three elements play a role in the appearance of water spots on your car’s paint after a thorough wash.

Car Washing Mistakes

How To Wash A Black Car Without Water Spots

Most vehicle owners are unaware that there is a correct technique to wash their automobiles, which is the opposite of pouring random cleaning chemicals and then washing the car with a towel. In addition, some car wash procedures might result in significant paint damage or deep scratches on your vehicle’s surface.

When you wash your automobile in the sun, the water you use to wash it evaporates rapidly. As a result, if you wash your automobile and don’t rinse it off right away, the filthy water will harden into the paint, leaving etched water stains when you eventually rinse.

Because conventional soaps and laundry detergents are not specifically designed for vehicle paintwork, they may leave stains when rinsed.

Acidic Rain

The fact that most individuals leave their automobiles parked in open places overnight is not news. Although parking your car in open places may not appear to be a terrible idea, it is recommended that you use car coverings when doing so – and it will be good in the long term.

Acid molecules, it appears, react on whatever surface they come into contact with; hence, if your car’s finish has leftover acid molecules on it, you’ll most likely notice stains after washing it.

Splashes of Dirty Water

This is the most common source of water spots; when you drive around the roads and streets, there’s a chance that another motorist may splash water on your car or that you’ll drive into a filthy water outlet.

As you drive, the dirty water will harden into your paint, and unless you use a properly formulated vehicle wash compound, the marks/spots left by the unclean water will be difficult to remove.

Dish soap and laundry detergent are not suitable for car washing

You must only use car-washing soap when it comes to soap. Only soap explicitly designed for washing automobiles will perform an adequate job of cleaning your vehicle.

Dish soap and laundry detergent are not suitable for car washing. They might not only cause wet stains on your automobile when you wash it, but they can also harm the paint.

Because it works softly yet efficiently on vehicles, a wash mitt is suitable for soaping down your car. It’s gentle on a car’s paint and won’t scratch it. It can also retain more water, allowing for quicker washing.


Although utilizing a hose’s “jet” or “spray” mode to rinse off your car may be faster, it can also lead to unattractive water stains on black cars. Therefore, it’s preferable to use a hose without a nozzle so that water may flow freely over your vehicle without leaving water stains.

Microfiber Cloth

To dry your automobile, you’ll need a microfiber cloth. A microfiber cloth has a smooth texture that makes it comfortable to use while drying automobiles, but it can also absorb a lot of water, reducing your effort.

Unlike any other cloth or towel, microfiber cloth has a superior capacity to trap lint from a car securely on its surface, avoid producing water stains and streaks.

Waxing your car’s surface is a highly efficient means of preventing damage to the paint, such as permanently baked dirt and scratches. In addition, waxing your automobile provides an extra layer of protection.

The watermarks on your automobile would only be on the surface of the wax coat if it had been waxed. And, unlike when they become trapped on a car’s paint, such spots would be easier to remove from the wax layer.

When you detect some water spots on your black automobile, use a water spot remover to remove them. 

How to Get Water Spots Out of Your Car’s Paint

So you’ve tried everything and still have water spots, what do you do now? We’ll go over a couple of ways in order of least to most aggressive. 

The Clay Bar Method: A clay bar may be used to remove mineral deposits, dirt, and filth that has become trapped. Simply keep the surface moist and soapy while rubbing your clay in, folding it over to show a new surface every so often.

Water Spot Removal With Distilled Water and White Vinegar Solution: Natural acetic acid in white vinegar dissolves calcium carbonate and other minerals quickly. White vinegar has a pH of 2.5, making it acidic and potentially damaging to your clear finish. To reduce the intensity, combine it with equal parts distilled water in a spray container.

Water Spot Remover or Mineral Deposit Remover: Phosphoric acid, more robust than vinegar with a pH of less than 3, is commonly found in these items. Calcium carbonate and other minerals are more resistant to MDR compounds.

Wheel Acid: Because it’s designed to remove thick, fundamental brake dust deposits, it generally contains very corrosive hydrofluoric acid.

Compounding And Polishing: If your automobile has been exposed to acid rain, you may see tiny etchings on the clear coat’s surface. The only method to flatten the clear coat is to polish it or wet-cut it.
