The Challenge of Oil Stains
Oil stains on concrete can be a real challenge to remove. Whether it’s from a leaky car or a spilled container, oil stains can leave a stubborn mark on the concrete surface. Cleaning oil off concrete requires the right technique and tools to effectively remove the stain.
Types of Oil Stains
There are different types of oil stains that can occur on concrete, including motor oil, cooking oil, and grease. Each type of oil stain may require a slightly different approach to effectively remove it.
The Penetrating Power of Oil
Oil has a knack for penetrating into porous surfaces like concrete, making it difficult to remove. It can seep deep into the concrete and leave a lingering mark that is tough to clean. Regular cleaning methods, such as scrubbing with soap and water, may not be enough to completely eradicate oil stains.
Additionally, oil stains can attract dirt and dust, making the stain even more noticeable and harder to remove. Therefore, it’s important to address oil stains as soon as possible to prevent them from becoming more problematic over time.
Pressure Washing as a Solution
Pressure washing is a popular method for removing oil stains from concrete surfaces. The high-pressure water stream can effectively break up the oil and flush it away. However, it’s important to use the right tools and techniques to avoid damaging the concrete surface.
Before pressure washing, it’s recommended to pretreat the oil stain with a degreaser or an oil stain remover. This will help to loosen and break up the oil, making it easier to remove during pressure washing.
When pressure washing, it’s crucial to use the appropriate pressure setting and nozzle to avoid damaging the concrete. Too much pressure can erode the concrete surface, while too little pressure may not effectively remove the oil stain.
Other Options to Consider
If pressure washing is not an option or doesn’t completely remove the oil stain, there are other methods to try. Using absorbent materials, such as kitty litter, sawdust, or baking soda, can help to absorb the oil from the surface. These materials should be spread over the stain, left to sit for some time, and then swept away.
Alternatively, there are commercial oil stain removers available that can be applied to the stain, followed by scrubbing with a brush. These removers are designed to specifically target oil stains and can be effective in removing stubborn marks.
It’s important to remember that oil stains on concrete may require multiple cleaning attempts before they are completely gone. Persistence and patience are key when trying to remove oil stains.

However, the effectiveness of pressure washing can vary depending on several factors.
Surface Type
The type of concrete surface being treated can affect the effectiveness of pressure washing. Smooth surfaces, such as garage floors or driveways, are generally easier to clean compared to rough or textured surfaces. The pressure washer’s nozzle and spray pattern should be adjusted accordingly to ensure proper coverage and cleaning.
Oil Stain Severity
The severity of the oil stain also plays a role in determining the effectiveness of pressure washing. Fresh or recent stains are generally easier to remove compared to old and deeply ingrained stains. In some cases, pre-treating the stain with a degreaser or oil remover before pressure washing may be necessary to achieve optimal results.
Pressure Washer Settings
The pressure and flow settings of the pressure washer can significantly impact the cleaning effectiveness. The pressure should be set to an appropriate level that is strong enough to remove the oil stain but not so high that it damages the concrete surface. It is recommended to start with a lower pressure setting and gradually increase if needed.

Start by sweeping or using a leaf blower to remove any loose dirt, leaves, or other debris from the concrete surface. This will prevent any additional particles from interfering with the cleaning process.
2. Apply a degreaser:
Next, apply a concrete degreaser or an oil stain remover to the oil-stained areas. Be sure to read and follow the instructions on the product label. Use a brush or broom to work the degreaser into the stained areas, allowing it to penetrate the oil and lift any embedded dirt or grime.
Tip: It is important to choose a degreaser that is specifically designed for use on concrete and is safe for the environment.
3. Let the degreaser soak:
After applying the degreaser, allow it to soak into the oil stain for the recommended amount of time. This will vary depending on the product used, so refer to the instructions for guidance. Allowing the degreaser to penetrate the stain will help to break down the oil and make it easier to remove.
4. Scrub the surface:
Using a stiff-bristle brush or a push broom, scrub the stained areas vigorously. Focus on the oil-stained spots but also scrub the surrounding concrete to ensure a consistent appearance. Apply additional degreaser if needed. This step helps to loosen and lift the oil from the concrete surface.
Caution: Wear goggles and gloves to protect yourself from splashes and to avoid direct skin contact with the degreaser or any chemicals used in the process.
By following these preparation steps, you’ll be ready to effectively pressure wash oil off your concrete surface, resulting in a clean and oil-free area.
Selecting the Right Equipment
