How To Clean Power Steering Fluid Off Engine

Power steering fluid leaks can be a common issue in vehicles, and if not addressed promptly, they can leave unsightly stains on your engine. Not only do these stains affect the appearance of your engine bay, but they can also lead to corrosion and other problems over time. In this guide, we will walk you through the steps on how to clean power steering fluid off your engine, keeping it looking clean and preventing potential damage.

Materials Needed:


Before working on your engine, it’s important to prioritize safety. Wear gloves to protect your hands and safety goggles to shield your eyes from any splashing chemicals or debris.

Step 2: Locate the Leak

Identify the source of the power steering fluid leak. This might require you to inspect your engine bay carefully. Once you’ve located the leak, it’s a good idea to fix it to prevent future stains.

Step 3: Prepare the Engine

If your engine is hot, allow it to cool down before cleaning it. Cleaning a hot engine can cause rapid evaporation of the cleaning agents and may not be as effective. You can also cover sensitive electrical components or exposed air intakes with an engine cover or plastic bags to prevent water or cleaning solutions from entering them.

Step 4: Apply Degreaser

Apply an engine degreaser or cleaner to the affected areas. Be sure to follow the manufacturer’s instructions for the product you are using. Typically, you will need to spray it evenly over the stained areas.

Step 5: Scrub Gently

Use a soft-bristle brush to gently scrub the stained areas. Be cautious not to scrub too hard, as this can damage the engine’s finish or paint. Focus on the stained spots and areas around the power steering fluid leak.

Step 6: Rinse

After scrubbing, rinse the engine with water. You can use a hose or pressure washer for this step. Make sure to rinse thoroughly to remove all traces of the degreaser and loosened power steering fluid.

Step 7: Repeat as Necessary

If the stains are stubborn, you may need to repeat the degreasing and scrubbing process. Some stains may require multiple rounds of cleaning.

Step 8: Dry the Engine

Use clean, lint-free cloths or rags to dry the engine thoroughly. Ensure that there is no standing water left on the engine components.

Step 9: Prevent Future Leaks

To avoid future power steering fluid leaks, regularly inspect your power steering system for signs of wear or damage. Address any issues promptly to prevent staining and potential damage to your engine.

Step 10: Inspection and Maintenance

Now that your engine is clean, it’s a good time to inspect your power steering system thoroughly:

  • Check Hoses and Connections: Examine the power steering hoses and connections for any signs of wear, cracks, or leaks. If you find any issues, replace them promptly to prevent future fluid leaks.
  • Tighten Connections: Ensure that all hose clamps and fittings are properly tightened. Loose connections can lead to fluid leaks over time.
  • Check Fluid Level: Verify that the power steering fluid level is within the recommended range. If it’s low, top it up with the correct type of power steering fluid as specified in your vehicle’s owner’s manual.
  • Inspect the Power Steering Pump: Look for any visible damage or signs of a leaking pump. If you notice problems with the pump, such as noisy operation or visible leakage, it may need to be replaced.

Step 11: Protecting Your Engine

To help prevent future power steering fluid stains on your engine:

  • Use a Power Steering Stop Leak Additive: If your power steering system has minor leaks that are hard to pinpoint or fix, consider using a power steering stop leak additive. These products can often help seal minor leaks, reducing the chances of stains on your engine.
  • Regular Maintenance: Stay on top of your vehicle’s regular maintenance schedule. This includes oil changes, power steering system checks, and inspections by a qualified mechanic. Timely maintenance can help catch and fix issues before they become major problems.
  • Park on Clean Surfaces: Whenever possible, park your vehicle on a clean surface to minimize exposure to dirt, debris, and potential fluid leaks.

Step 12: Final Cleaning Touches

After you’ve inspected and maintained your power steering system, take a few extra steps to keep your engine bay looking great:

  • Apply an Engine Dressing: You can apply an engine dressing or protectant to give your engine components a clean, glossy appearance. Be sure to choose a product that is safe for use on engines and follow the instructions carefully.
  • Regularly Wipe Down: Periodically wipe down your engine bay with a clean, damp cloth to remove dust and minor stains. This maintenance task can help keep your engine looking clean and well-maintained.
