Dealing with Hydraulic Fluid Spills on Concrete: A Comprehensive Guide

How to get hydraulic fluid out of concrete? Encountering a hydraulic fluid spill on concrete can be quite a hassle, but with the right approach, you can effectively manage the situation. Here’s a step-by-step guide on how to tackle it:


Contain the spill immediately to prevent it from spreading further. Use absorbent materials like kitty litter, sawdust, or rags to surround the spill and absorb as much of the liquid as possible.


Apply a generous amount of absorbent material over the spill and allow it to sit for some time. The absorbent material will soak up the hydraulic fluid. Replace saturated absorbent with fresh material as needed until no more liquid is being absorbed.

 Residue Removal:

Once the majority of the liquid is absorbed, use a scraper or putty knife to gently scrape away any remaining residue on the concrete surface. Be cautious not to scratch the concrete itself during this process.

Stain Removal (Optional):

For persistent stains, you can opt for additional stain removal methods:

  • Degreaser: Utilise a degreaser specially formulated for oil and grease stains. Follow the product instructions carefully for application and rinsing.
  • Dish Soap: If the stain persists, create a solution of warm water and dish soap. Scrub the affected area with a stiff brush and rinse thoroughly.
  • Poultice (Advanced): For tougher stains, consider using a poultice made with trisodium phosphate (TSP) and calcium carbonate (whiting lime). However, always test this method in a small inconspicuous area first to ensure compatibility with the surface.

Additional Tips:

  • After using degreaser or dish soap, consider using a pressure washer to thoroughly clean the concrete surface. Adjust the pressure washer settings to avoid damaging the concrete.
  • Ensure proper ventilation when using cleaning solutions to prevent exposure to fumes.
  • Dispose of the absorbed hydraulic fluid and cleaning materials responsibly according to local regulations.

If the hydraulic fluid spill is extensive or if you’re uncertain about handling it yourself, it’s advisable to seek professional assistance from a cleaning service that specialises in hazardous materials. Your safety should always be the top priority.

By following these steps and tips, you can effectively manage hydraulic fluid spills on concrete surfaces, restoring them to their pristine condition with minimal hassle.

Does hydraulic fluid damage concrete?

So, you’ve got a hydraulic fluid spill on your concrete surface – not ideal, but not necessarily catastrophic either. In the short term, hydraulic fluid doesn’t pose an immediate threat to cured concrete. However, over time, there are a few things to watch out for.

First off, there’s staining. Hydraulic fluid can leave stubborn stains on the concrete, which, let’s face it, isn’t exactly a look you’re going for. These stains can be a pain to remove and can really mess with the visual appeal of your concrete.

Then, there’s the potential weakening of the concrete. While it won’t happen overnight, prolonged exposure to hydraulic fluid can gradually weaken the concrete by messing with its internal structure. This isn’t something you want, especially if your concrete is already dealing with a lot of stress or if spills happen frequently.

And let’s not forget the environmental impact. Hydraulic fluid can seep into the ground, contaminating the soil and groundwater. This is a big no-no and can have serious consequences if not dealt with properly.

So, in a nutshell, cleaning up hydraulic fluid spills pronto is the way to go. By doing so, you’ll not only prevent unsightly stains in the short term but also minimise the risk of long-term issues like weakening concrete and environmental contamination. It’s all about staying proactive and keeping your concrete in top-notch condition.
