Overspraying on car or garage doors can happen, but that doesn’t mean it’s the end of the world! Before you panic or hope your client doesn’t notice it, take a deep breath because emulsion or coal tar asphalt sealers are removable. And, these seven best asphalt sealer removers can make the process quick and effortless.

Some are readily available and require minimal investment, while others are powerful enough to remove the most stubborn dried sealer and grease.

The Secret to Growing Your Asphalt Business Fast 

1. Karnak Karna-Klean

Karnark Karna-Klean has a citrusy and fruity scent, making you think it’s unreliable, but you’ll be surprised. Its formula can quickly and effectively remove stubborn stains, ranging from grease to dried sealer. And, yes, it can also remove asphalt sealer from concrete! 

Karna Karna-Klean is a pro grade asphalt and tar remover.

Using the Karnak Karna-Klean couldn’t be simpler. Generously spray it on the surface, let it settle for a few minutes, and then rinse it off with water. 

Since it has a potent asphalt sealer remover blend, we highly suggest wearing protective gear like gloves and PPE. Never use this asphalt sealer remover on your skin.

2. Oil-Flo 

If you’re dealing with a large overspray area, you’ll find Oil-Flo’s 5-gallon pail (smaller sizes are available) more than enough to make the surface squeaky clean and asphalt sealer free. So, how does it work? 

Oil-Flo is a biodegradable asphalt sealer remover that doesn't contain harmful compounds

Oil-Flo binds with the asphalt sealer’s molecules and then dissolves them. Despite its effective formula, Oil-Flo doesn’t contain harmful compounds or leave nasty residues behind. As a matter of fact, it is 100% biodegradable! 

In addition to removing stubborn asphalt sealers, Oil-Flo can also effectively remove the following: 

  • Crude oil 
  • Grease 
  • Resins 
  • Waxes 
  • Motor oil 
  • Household stains like crayon marks and adhesive residues

If you want to remove asphalt sealers on wood, concrete, metal, and even clothing, you can rely on Oil-Flo to get the job done. Here’s how you should use Oil-Flo: 

  1. Spray Oil-Flo on the surface. You can also smudge it on the dried sealer and let it emulsify. Unlike Karnak Karna-Klean, you should sparingly use Oil-Flo. 
  2. Let Oil-Flo settle for a few minutes. 
  3. Then, rinse the area. 

When removing asphalt sealer overspray on a wall or garage door, we suggest placing a rag to catch the product waste and prevent it from going into the storm drains. 

Lexan and Plexiglass are not recommended with Oil-Flo. 

3. Paint and Epoxy Remover

You can also use paint and epoxy remover on overspray areas. They are cheap and available in most hardware stores, retail or online. The only problem is it’s not advisable on vehicles and walls; paint and epoxy removers are only for surfaces like concrete, masonry, and wood. 

Here’s how you should use paint and epoxy remover: 

  1. For concrete floors, apply a moderate amount on the stained area. 
  2. Wait for a few minutes. 
  3. Scrub the overspray area using a stainless steel stripper brush. Don’t aggressively brush, or else you’ll scrape the surface! For delicate surfaces, you can use a non-abrasive pad. 
  4. Don’t let the product dry on the surface. 
  5. Rinse the area using a power washer. 

How about floor strippers? You can also use it but don’t expect it to be effective as paint and epoxy removers. 

4. Goof Off Professional Strength Remover

Another go-to product you can use to remove asphalt sealer is the Goof Off Professional Strength Remover. Like Oil-Flo and Karnak Karna-Klean, Goof Off works well with different surfaces, including concrete, glass, and wood. If there is overspray on your car, Goof Off is safe to use. 

Goof Off can remove asphalt sealer overspray on concrete and metal

Using Goof Off is also simple. Spray a generous amount on a clean microfiber or directly on the surface and gently scrub it. Don’t handle this asphalt sealer remover without wearing laminate film gloves.

5. Odourless Mineral Spirits

If you don’t want to take the risk of damaging your car’s paint, odourless mineral spirits are a great option. Many car owners even use odourless mineral spirits for DIY car cleaning. 

However, it’s important to proceed with caution because it’s technically a paint thinner. And if you left it to dry, your vehicle may have a dull paint patch! Moreover, if you apply too much, there is a huge probability that you’ll also strip the clear coat. 

Here’s how to safely use odourless mineral spirits on your car. 

  1. Get a clean microfiber cloth. 
  2. Pour two tablespoons of odourless mineral spirits on the cloth.
  3. Place it gently on the asphalt sealer stain. 
  4. Allow the mixture to settle for only 2 minutes. Again, don’t leave it to dry!
  5. Once the stain loosens up, grab another cloth and wipe it off from the surface. 
  6. Wash with soap and water.

6. WD-40 (For Automotive Surfaces)

WD-40 is best for asphalt sealer stain on

If you’re uncomfortable using odourless mineral spirits, here is a favourite: WD-40. While we usually use WD-40 for lubrication and preventing rust, it is also an effective solution to removing asphalt sealer overspray. The caveat is it is only reliable on automotive surfaces. When applied anywhere else like doors and walls, don’t expect it can provide the same results as Oil-Flo. 

  1. Spray it on the affected car surface.
  2. Let it soak for a few minutes - doing so will emulsify the stain.
  3. Wipe the area with a clean cloth. 
  4. Due to WD-40’s greasy consistency, you will need to wash the area with soap and water.

7. Solvall

Solvall Cleaner is an asphalt sealer remover that doesn't leave any residues.

Solvall is another reliable asphalt sealer remover. Unlike WD-40, this slow evaporating all-purpose solvent doesn’t leave a greasy residue. It will also not leave a nasty stain. Plus, you can use it on different surfaces like glass and metal. 

Like other asphalt sealers removers that we’ve mentioned, you should apply Solvall on the surface, leave it for a few minutes, and agitate it using a soft brush or cloth. Then, rinse it with water. 

Bonus - Use Water 

Water is also an effective asphalt stain remover - provided that the overspray is still wet. Grab a hose and hose the area down with water. Remember, you only have a short window of time before an asphalt sealer dries! Act fast if you want to use water.
