How to Remove Yellow Stains from White Car Paint (STEPS)

How to remove yellow stains from white car paint?

You can remove the yellow stains from white car paint by spraying a vinegar-water mixture on the affected surfaces and by rubbing clay bars on the stains.

 

To remove the yellow stains from white car paint, you will need the following items:

  • A shampoo of balanced pH (Auto Factor Premium Car Wash shampoo is a good choice)
  • Distilled white vinegar and distilled water
  • Spray bottle
  • Clay bars
  • Microfiber towel
  • Painter’s tape
  • Electric powered orbital polisher

 

Here’s how you can remove yellow stains from white car paint:

  1. Wash your car with water and shampoo to remove temporary stains. You should choose a shampoo that has a balanced pH. This is important as deviations from the ideal pH may cause dulling of car paint and even scratches.In addition to this, it’s good to wash your car in the absence of direct sunlight. This will prevent the chipping of your car’s paint. Once you’ve finished washing your car, use a dry cloth to dry the car’s body completely.
  2. In a spray bottle, add distilled water and distilled vinegar to create a 50/50 concoction of vinegar and water. Using distilled liquids is important to obtain a mixture that is free of impurities.Vinegar has remarkable cleaning properties, which are often used to get rid of many types of tough stains. Use this solution to spray on the stained surfaces on the car’s body. Wait for 30 seconds and wipe the vinegar mixture off using a soft towel.
  3. Use a clay bar to clear out the impurities on the car’s surface and remove the remaining stains. For this, you will need to wet the affected areas on your car’s body and rub the clay bar upwards and downwards to deeply cleanse the surface of your car.It’s important to pay a little attention while carrying out this step because clay bars can harm the wax and ceramic coatings of your car if you are not careful.
  4. Carry out a paint correction technique if the yellow stain still remains on your car. However, the previous steps are most likely to remove that tough yellow stain from your car’s body. Paint correction may be a daunting task and may go wrong if not done properly.Cover the surface around the yellow spots using painter’s tape to prevent the paint from going outside the perimeter of the affected area.
  5. Frequent polishing of the car is also helpful in correcting the yellow spots on your car. You can use an electric-powered orbital polisher to polish your car at home.

 

Removing yellow stains from white car paint

 

What are the yellow spots on my white car?

The yellow spots on your white car can be patches of pollen grains, tree sap or bird droppings. These spots may be hard to remove. So you will need to follow the right procedure to clean the yellow spots off your car. This includes the use of a clay bar having low abrasive quality.

 

Why does white car paint turn yellow?

The white paint of your car may turn yellow because of acid rain, oxidation from sunlight, engine heat, rust  or asphalt deposition.

 

Acid rain

Acid rains are extremely harmful to the car’s paint and cause oxidation of the car paint. This oxidation results in the white paint turning yellow. This type of yellowing occurs on the top surfaces of the car such as the roof, trunk and hood. Industrial fallout can be another reason for yellow spots on these surfaces. You can avoid this type of yellowing by parking your car in sheltered spaces so that the acid rain doesn’t come in contact with the car’s paint.

 

Engine heat

The hood of the car embraces the engine. The engine dissipates a lot of heat that is responsible for the yellowing on the hood of the car. Since it’s not possible to prevent this heat, you may polish the hood of your car to keep it bright and shiny.

 

Rust formation

Rust may form underneath the car paint, especially if you live in coastal areas. This leads to the yellowing of the white car paint and occurs mainly under the car panels. You can spot these early signs to prevent severe rust formation as it is dangerous in the long run as well. Rust can damage the entire car surface.

 

Black asphalt deposits

If the white car paint on the bottom rocker panels of the car starts yellowing, it’s often because of tar or black asphalt deposits on the car surface that was left to sit for too long. To get rid of the stain, you will need to clear out the tar and clean the car surface using suitable methods such as claying to get rid of any other impurities.

 

Oxidation due to sunlight

Parking or washing your car in direct sunlight can cause overall yellowing of the white car paint. This is because the ultraviolet radiations of the sun cause oxidation of the car paint leading to the white paint turning yellow. This can happen over time when the car remains under direct exposure to sunlight for long periods.

The yellowing on the side door panels can happen due to water seeping into these spaces. To avoid this, always park your car in shaded spaces. You can also regularly clean the side door panels and mirror panels to remove any dirt and dust.

 

How to prevent yellow spots on white cars?

You can prevent yellow spots on white cars by following some safety precautions like parking the car in sheltered spaces, washing the car frequently and getting the wax treatment done regularly.

To prevent yellow spots on white cars, you will need these tools:

  • Hosepipe
  • Microfiber towel
  • Shampoo of right acidity
  • Wax
  • Polish

 

Here are some tips to prevent yellow spots on white cars:

  1. Always park your car in sheltered spaces, preferably garages, especially during the daytime. Direct exposure of a car’s surface to sunlight can cause the car’s paint to crust and crack. This is harmful in the long run as it may lead to rusting as well. In addition to this, exposure of the car’s surface to acid rain leads to permanent yellowing of the pristine white paint of your car.
  2. You must wash your car regularly in the morning or evening to remove dirt and dust particles from the surface of the car. Washing your car helps to keep the shine of the car paint intact. It also helps to prevent scratches due to fine dirt particles.
  3. Use a car-based shampoo to wash your car. The shampoo must have a pH of the right balance that doesn’t harm the car paint.
  4. Always use a microfiber towel to clean the car after washing. Using rough clothes can cause fine scratches on the car’s body that can cause rusting of the metal body of the car and consequently, yellow spots on the car’s surface. Never clean the dust off your car without washing. The fine dust particles can rub over the car surface and cause damage to the car paint by making it chip off from the car body and leading to rusting or yellow spots.
  5. Use wax to provide added protection to the car paint against pollen and tree sap that cause yellow spots on the white paint. Your car must be treated with wax at least once every month. If needed, you can also polish your car to secure the luster and brightness of the car paint.
  6. Do not park your car under the trees to prevent bird droppings and tree sap from falling on the car’s white paint. These are the main reasons for yellow spots on the car paint.
