To effectively remove road oil, especially petroleum-based substances like tar, a common and efficient solution is using WD-40.
Understanding Road Oil and Tar Removal
Road oil, often in the form of tar, is a petroleum-based substance that can adhere to various surfaces, particularly vehicle paintwork. Its sticky and stubborn nature makes it challenging to remove with just soap and water. The key to its removal lies in using a solvent that can break down its petroleum base.
The Role of Solvents in Oil Removal
Solvents work by dissolving the oil or tar, allowing it to be easily wiped away. Many commercial tar removers contain specific solvents designed for this purpose. WD-40 is one such product, widely advertised for its ability to tackle petroleum-based stains.
Step-by-Step Guide: Using WD-40 for Road Oil Removal
Utilizing WD-40 is a straightforward process to effectively eliminate road oil and tar from surfaces. Its formulation includes a solvent specifically designed to break down petroleum-based compounds, making removal much easier.
Here's how to use it:
- Preparation: Ensure the affected area is relatively clean of loose dirt or debris. While not strictly necessary, a quick rinse can help.
- Application:
- Spray: Directly spray a generous amount of WD-40 onto the road oil or tar spot.
- Wipe: Alternatively, you can wipe WD-40 onto the affected area using a clean cloth.
Ensure the entire stained area is thoroughly covered.
- Dwell Time: Allow the WD-40 to sit on the road oil for 10 to 30 minutes. This crucial waiting period allows the solvent to penetrate and break down the petroleum-based asphalt.
- Wipe Away: After the recommended waiting time, use a clean, soft cloth to gently wipe off the dissolved road oil. You should notice the tar residue lifting easily.
- Rinse and Clean: Once the road oil is removed, it's advisable to clean the area with soap and water to remove any WD-40 residue, especially from vehicle paint. This helps prevent streaking or attracting new dirt.
Why WD-40 Works
WD-40 contains a powerful solvent that directly fights against petroleum-based asphalt. This chemical action breaks down the molecular structure of the tar, changing it from a sticky solid into a more manageable liquid form that can then be easily wiped away with a clean cloth.
