Use a high-quality automotive soap such as Chemical Guys Mr. Pink Foaming Car Wash Soap for cleaning. Avoid using abrasive sponges or cleaning cloths, as they can scratch the paint and damage it. You should also use clean water for cleaning and rinsing when washing the car.

6. Finish by drying the car with a clean microfiber cloth.

Modern automotive finishes tend to be more resistant to contaminants that cause dull spots than past ones. With this kind of finishes, you can use a clay bar to fix dull spots. However, This method works efficiently if the dull spots are still new and fresh.

Using a Clay Bar to fix dull spots on car paint doesn’t cause any harm to the paint. It is, therefore, a safe method for all types of paints, irrespective of the color. In addition to the safety, it is a quick and cost-effective method.

Method 3: Scratch & Swirl Remover

If the dull spots on your car’s paint result from oxidation or scratches that trap dust and contaminants, you will need a Scratch & Swirl Remover Compound to remove them.

If you are dealing with cured and more stubborn dull spots on car paint, you should use a more intensive method like hand buffing. It is performed by hand without a buffing or polishing machine.

This makes it more labor-intensive but reliable for removing stubborn dull spots on car paint. However, hand buffing is much safer and reduces the risk of possibly burning the car’s paint – this happens when machine polishing is done at very high speeds.

For our case, we highly recommend the Chemical Guys Scratch and Swirl Remover Compound Polish for hand buffing. This polish is safe to use on virtually all types of paints, no matter the finish or color.

NOTE: Buffing with hand compound not only fixes the dull spot but also brings back the paint’s gloss look. It is also a less intrusive method that guarantees results without damaging the paint.

Method 5: Machine Polishing

Finally, Machine polishing is another method to fix dull spots on car paint. If the area with dull spots on the car is too big for hand buffing, machine polishing is here for the rescue.

This method can either be gentle on the paint surface or quite aggressive depending on the two things; the type of machine that you use and the buffing pad attached to the machine.

5 Leading Causes of Dull Spots on Car Paint

Dull spots on car paint can arise from various factors, including environmental exposure, improper maintenance, and chemical damage.

These imperfections not only affect your car’s appearance but can also compromise the paint’s protective layer. In this section, we’ll discuss five common causes of dull spots on car paint.

1. Contaminants

Contaminants are the leading cause of dull spots on car paint. They come in different forms, from environmental compounds to tree sap, droppings from birds, bug residue, and acidic rain.

Sometimes, these contaminants can be easily removed when you wash off the car and reveal the shiny, sleek paintwork underneath. Alternatively, if they tend to be more stubborn, one can use chemical cleaners to remove them.

2. Oxidation

Oxidation is another thing that causes dull spots on car paint. It occurs when your can paint is exposed to elements that don’t come off during cleaning.

Old vehicles are more prone to oxidation as they lack the high-end finishes found in modern cars. Besides, dull spots in car paint due to oxidation can appear just about anywhere on the car’s body, either in patches or as a widespread haze that dulls the entire surface.

3. Scratches

Whenever a sharp object rubs against the car, it causes scratches. Driving offroad regularly puts your vehicle at a greater risk of being scratched by sand and dirt.

Once the car is scratched, dirt and other contaminants get trapped in the area where the scratching occurs. With time, the scratches end up causing the paint to become dull and unsightly.

4. Improper Washing Techniques

Improper washing methods is another factor that leads to dull spots on car paint. It includes the use of harsh detergents to clean the car, abrasive scrubbing, and dirty sponges.

With improper washing, you leave behind visible marks that diffuse the light enough to make the car paint look dull. It can also give contaminants more grip, cling tighter on the surface, and add to the dull spots.

5. Paint Wear and Lack of Maintenance

Aging causes natural wear on a car’s paint over time, breaking down the clear coat and leading to dullness and fading.

Additionally, a lack of proper paint maintenance and care, such as skipping regular washing and waxing, accumulates dirt and contaminants, accelerates paint damage, and makes restoration more difficult.
