Image Blog Details

Finding paint overspray on your car can be frustrating, especially when you take pride in keeping your vehicle in top condition. Whether it’s from a nearby paint job, roadwork, or industrial coatings, paint overspray can affect your car’s finish and appearance. Luckily, there are effective ways to remove it without damaging your vehicle’s paint.

At San Diego Select, we specialize in professional car care and paint restoration services to keep your car looking flawless. In this guide, we’ll share expert-approved techniques to safely remove paint overspray and protect your car’s shine.

1. What is Paint Overspray?

Before diving into removal techniques, it’s important to understand what paint overspray is and how it affects your car’s surface. Overspray occurs when fine paint mist lands on unintended surfaces, leaving behind a rough texture. Depending on the type of paint (water-based, oil-based, or industrial coatings), removal methods will vary.

2. How to Identify Paint Overspray

Step 1: Feel the Surface

  • Lightly run your fingers over the car’s paint.
  • If it feels gritty or rough, you likely have paint overspray.
  • Check windows, mirrors, headlights, and trim, as overspray can settle anywhere.

Step 2: Conduct the Fingernail Test

  • Gently scratch a small area with your fingernail.
  • If paint flakes off, a simple wash or clay bar treatment might be enough.
  • If it remains stuck, stronger removal methods may be needed.

3. Best Methods to Remove Paint Overspray

A. Wash Your Car First

  • Start with a thorough car wash using high-quality soap and microfiber mitts.
  • Dry the surface completely before proceeding.
  • Explore our Wash Memberships for regular car maintenance and protection.

B. Use a Clay Bar Kit

A clay bar kit is one of the safest and most effective methods to remove paint overspray.

Steps to Use a Clay Bar:

  1. Spray the affected area with clay lubricant.
  2. Gently glide the clay bar over the surface.
  3. Knead and fold the clay bar as it collects paint particles.
  4. Wipe the surface with a microfiber towel.

This method is safe for clear coats, glass, and chrome.

C. Use a Rubbing Compound

If a clay bar doesn’t remove paint overspray, try a rubbing compound.

Steps:

  1. Apply a small amount of rubbing compound to a microfiber cloth.
  2. Rub the area using light circular motions.
  3. Buff off any residue with another clean cloth.
  4. Protect your paint by applying a car wax or sealant.

D. Use a Paint-Friendly Solvent

For stubborn overspray, a solvent-based remover like WD-40 or Goo Gone can help.

Steps:

  1. Apply a small amount of solvent to a microfiber cloth.
  2. Lightly rub the overspray in circular motions.
  3. Rinse with soap and water to remove residue.

Caution: Always test the solvent on a small hidden area first to avoid damage.

E. Remove Overspray from Windows with a Plastic Razor Blade

If overspray is on your windows, a plastic razor blade can help remove it safely.

Steps:

  1. Spray glass cleaner over the affected area.
  2. Hold the plastic razor blade at a 45-degree angle.
  3. Gently scrape the overspray without applying too much pressure.
  4. Wipe with a clean microfiber towel.

4. Preventing Paint Overspray in the Future

To avoid paint overspray, follow these preventive steps:

  • Park away from painting zones and construction sites.
  • Use a car cover when parking near high-risk areas.
  • Apply wax or a ceramic coating to create a protective barrier.
  • Visit our expert Services page for top-tier paint protection treatments.

Will was AMAZING! My car needed full interior detailing from rain getting inside this winter, and it hadn’t been fully cleaned in years. He scheduled me ASAP and was super thorough when going over the process. He picked up the car from me and brought it back quicker than expected so I didn’t have to go anywhere, and it looked new on the inside. It had a new car scent and all the seats and floors that were damaged from rain/dirt were totally clean. I’m so happy with the services and feel like it’s a different car now - I would recommend him to anyone in SD :) !! Thank you so much!!

Had an amazing experience with San Diego Select Detailing. They did a fantastic and thorough job of detailing my new car after it was transported from a dealership in another state, and also detailed two other vehicles at our household (one of which had laundry detergent spilled in the trunk). Each car came out looking fantastic. They come fully equipped to do a professional level detail job at the location of your choosing, which was very convenient. Can't wait to use their services again.

I had Hyundai Elantra detailed before gifting it to my sister. Will and Ed were able to accommodate me same day which was really nice of them. The fact that they come to you is also very convenient.The car looked as good as the day I bought it from the dealership. My sister was so stoked. She was beaming the whole three hours we were handling insurance and DMV stuff

Frequently Asked Questions

Why Should I Detail My Car?

Perfection & Protection.

Frustrated with everything that the car wash leaves behind?
Does your paint not shine like it used to?
In love with your car and want to preserve your investment for the long term?

That is why we are here. Not only do we leave you with flawless results, but we make sure that your paint, leather, and other materials are protected for years to come. We will treat your car (and you) like one of our own.

Do I need a "Shampoo Treatment"?

The shampoo and hot water extraction is the best possible care for your FABRIC seats.

We will bathe your seats in thick foam shampoo, agitate it with a fabric brush attachment on a drill, and then extract all the grime, dirt, stains and contaminant from the seats with hot water at 210ºF. If your seats need a refresh, this is as good as it gets. Because the service takes 45 minutes on average, and only a small percent of vehicles need it we charge extra for it. Don't worry - its only $50 extra. Totally worth it.

Will My Scratch "Buff Out"?

Do you have any little scrapes and scratches that bother you?

We can handle it.. to an extent. We are polishing experts - so if the scratch isn't too deep, we can get it out. Ever heard of "The Fingernail Test", this is a great way to know if your scratches are fixable. If you feel the scratch will your fingernail and you can feel a groove in the paint, it it probably a little bit too deep ~in the sections where the groove is~

What is a "Clay Bar"?

A clay bar is exactly what it sounds like, a little ball of malleable puddy.

This is used in the decontamination phase of the detail to prepare your paint for protection. Clay Bar Detailing is essential for preparing your vehicle's paint for protection by ensuring it is free of contaminants.

Every exterior detail has 3 phases: 1. Wash 2. Decontaminate 3. Protect. The decontamination stage is responsible for removing from the paint everything that doesn't come off from the wash.

Remember when you bought your car and the paint was smooth to the touch? That is the goal of this stage. Remove all the crusty junk that is stuck to you paint. This way, when we apply sealant (protection) to your paint it will adhere to the paint itself, rather than the junk sitting on the surface. This will give the sealant its longest possible useful life.

Why "Wax" My Car?

For the same reason that you get an oil change. Engines are expensive to replace (8-15K) so we take good care of them. So is your paint - the average paint job costing around $5,000. If you don't protect your paint with some type of ceramic, wax, or sealant, your paint WILL fail.

In San Diego, our biggest enemy is the sun, or the salt if you live near the beach. Next time you are in a big parking lot, look around at the hoods of the vehicles. You will notice around 1/6 vehicles have completely delaminated clear coat.

That means the paint looks like dead skin on the surface and you could peel it off with you fingers. Not pretty. There is a simple solution to ensure your vehicle never ends up like this. Exterior Detailing. Bonus points for a ceramic coating with is the best protection possible.
