Power steering fluid is an essential component of your vehicle’s steering system. It helps to lubricate the steering mechanism, making it easier for you to turn the steering wheel. However, if this fluid leaks onto your concrete driveway or garage floor, it can create a stubborn stain that’s difficult to remove. But don’t worry, with the right tools and techniques, you can clean power steering fluid off concrete like a pro. In this guide, we’ll walk you through the steps to effectively remove these stains and restore your concrete to its original condition.

Understanding Power Steering Fluid Stains

Before we delve into the cleaning process, it’s important to understand what makes power steering fluid stains so challenging to remove. Power steering fluid is a type of hydraulic fluid that is oil-based. This means that it can penetrate deeply into the porous surface of concrete, creating a stain that’s not only unsightly but also potentially damaging to the concrete itself.

When power steering fluid comes into contact with concrete, it can seep into the pores of the material, causing discoloration. Over time, if left untreated, this can lead to the concrete becoming brittle and cracking. Therefore, it’s crucial to tackle these stains as soon as possible to prevent any long-term damage.

Materials and Tools Needed

Before starting the cleaning process, it’s important to gather all the necessary materials and tools. Having everything at hand will make the process smoother and more efficient. Here’s what you’ll need:

  • Absorbent material (like cat litter or sawdust)
  • Stiff-bristled brush
  • Detergent or concrete cleaner
  • Bucket
  • Water
  • Protective gloves
  • Eye protection

It’s important to note that when choosing a detergent or concrete cleaner, opt for one that’s specifically designed to break down oil-based stains. This will ensure the most effective cleaning.

Steps to Clean Power Steering Fluid off Concrete

Now that you understand the nature of power steering fluid stains and have gathered your materials, it’s time to get to work. Follow these steps to clean power steering fluid off concrete like a pro:

  1. Put on your protective gloves and eye protection. This will keep you safe from any potential harm caused by the cleaning products.
  2. First, you’ll need to absorb as much of the power steering fluid as possible. Sprinkle a generous amount of your absorbent material over the stain. Let it sit for several hours, or ideally, overnight. The absorbent material will soak up the fluid, making the stain easier to clean.
  3. After the absorbent material has done its job, sweep it up and dispose of it properly.
  4. Next, prepare a cleaning solution. Mix your chosen detergent or concrete cleaner with water in a bucket according to the manufacturer’s instructions.
  5. Apply the cleaning solution to the stain. Use your stiff-bristled brush to scrub the area vigorously. The brush will help to lift the stain from the pores of the concrete.
  6. Once you’ve scrubbed the area thoroughly, rinse it with clean water. If the stain is still visible, repeat the process until it’s completely gone.

Remember, patience is key when dealing with stubborn stains. It may take several attempts to completely remove the stain, but with persistence, your concrete will be as good as new.

Preventing Future Stains

Once you’ve successfully cleaned the power steering fluid off your concrete, you’ll want to take steps to prevent future stains. Here are a few tips:

  • Regularly check your vehicle for leaks. If you notice any signs of a power steering fluid leak, get it repaired as soon as possible.
  • Consider using a concrete sealer. This can provide a protective layer on the surface of your concrete, preventing stains from penetrating deeply.
  • Always clean up spills immediately. The sooner you tackle a spill, the less chance it has to seep into the concrete and create a stain.

By following these preventative measures, you can keep your concrete looking its best and avoid the hassle of dealing with stubborn power steering fluid stains in the future.


Cleaning power steering fluid off concrete may seem like a daunting task, but with the right tools, materials, and techniques, it’s entirely doable. Remember, the key is to act quickly to prevent the fluid from penetrating deeply into the concrete. With patience and persistence, you can effectively remove these stains and restore your concrete to its original condition.

So, roll up your sleeves and get to work. With this guide, you’re now equipped to clean power steering fluid off concrete like a pro. Good luck!
