Asphalt stain isn’t something good to look at. They’re oily and disgusting. Hiring a professional is always an option but it costs money. Luckily, they’re super easy to remove and you can do it yourself. 

How to remove asphalt from concrete? 

You can start with soap or detergent. It’s the most cost-effective option. They’re great against oil-based asphalt but not as good as muriatic acid. Mix 10% of the muriatic acid in the water and that should do the job! And lastly, you can use some good old concrete cleaners.

Anyway, that was just a brief answer. There’s more to discuss regarding the asphalt removal process.

Removing Asphalt Stain From Concrete: 3 Simple Methods

Asphalt removal processes are quite simple. On top of that, these methods don’t require too many ingredients.

The only thing that matters are the ingredients that you have access to. But don’t worry; they only require basic household ingredients. 

Luckily, the ingredient used in asphalt removal is super accessible. You can get them easily from any nearby store or order online. 

If you have a friendly neighbor, maybe give them a knock!

But there’s one thing you should note. Removing asphalt isn’t the same as taking off asphalt sealer from concrete

Anyways, back to the topic. Since there are multiple methods; I have decided to list them one by one. 

Simply take a seat, relax and go through all of them. Pick any method that uses ingredients that are easily accessible to you. 

Method 1: Use Soap Or Detergent 

I have picked this method first because anyone can use this. This method isn’t the most effective out of all but accessible to everyone. 

Since asphalt stains are oily, soap is a great option to consider. Almost all sorts of asphalt stains are removable by soaps. 

By the way, note that soaps are only good for stains like asphalt. You can’t use them to get rid of latex paint from concrete. For that, you’ll need a paint stripper. 

Anyways, here are some of the steps you’ll have to follow- 

Step 1: Use Soap Or Make a Detergent Mixture

Get some soaps that you use to clean dishes. You can also take a bucket and make a detergent mixture instead.

Use the soap on the stained area. If you’re detergent, pour some of that mixture on the area. 

Wait 2-3 minutes to let it loosen the stain for you. 

Step 2: Scrub the Stain & Repeat 

Okay, this is the physical part that will seem annoying. Take an abrasive scrubber and start rubbing the stain. Do it for 5-6 minutes. 

When you’re done, use water to clean the area. Inspect the stained area afterward. If there are still any stains left, do another round of scrubbing. 

Method 2: Use Muriatic Acid 

If your asphalt stain is too hard, you’ll have to take drastic measures. Muriatic acid is considered one of the strongest solutions that work against oil. 

Since asphalt stains are petroleum-based, the acid can easily dissolve them. 

Get some safety gloves and headwear. This should prevent you from coming in direct contact with the acid. 

Step 1: Make a Muriatic Acid Solution

You can’t use any metal bucket or bowl for this. You’ll specifically need glass or plastic that is resistant to acid. 

Get some water in the container that you’re going to use. The correct amount of muriatic acid is 10% of total water. You can also use muriatic acid to etch concrete

Simply pour the muriatic acid into the water. Stir it with a stick or ladle for a better mixture. 

Step 2: Apply the Muriatic Acid Mixture On the Area

Pour the solution into the stained area with great care. You can use an acid-resistant plastic sprayer to make it easier.

When you’re done, wait for 2-3 minutes. The solution will then foam upon the area. After that, wash the muriatic acid by rinsing the area. 

If there are still some left, repeat the process. You can also increase the amount of muriatic acid in the solution.

But be careful not to put much as that’ll damage the surface.

Method 3: Use a Concrete Cleaner

If you want a quick solution, the concrete cleaner method is for you. These cleaners contain special chemicals that can dissolve pretty much anything.

To save you some time, I’ve listed some of my favorite cleaners:

Product 1
Product 2

You can now choose whichever cleaner you like more and get started! 

You can also make a homemade concrete cleaner by yourself. It only requires washing soda and vinegar. 

It’s a great alternative if you don’t want to buy a commercial concrete cleaner. 

Apply the Concrete Cleaner

The whole process is not as tough as it sounds. It’s very convenient and time saving. Let’s move on to the process: 

  • Start by spraying the concrete cleaner on the stained area. Make sure you’re not leaving a single spot behind. 
  • After that, wait for 5-6 minutes to let it take effect. Thoroughly wash the area to get rid of the cleaner. 

Concrete cleaners are meant for all sorts of stains. That’s why it may not be super effective against the asphalt. 

In such cases, repeat the step 2-3 times to completely get rid of it. 

These techniques should help you remove the asphalt from concrete. If these methods seem bothersome, call an expert and explain your problem.
