Oil & Grease Stains

Oil and grease stains are typically caused by spills or leaks from vehicles, machinery, or even cooking oils. When these substances come into contact with the porous surface of pavers or concrete, they can seep into the tiny spaces, creating stubborn stains. The porous nature of these materials allows the oil and grease to penetrate deeply, making the removal process challenging (and at times, impossible). Additionally, factors like weather, age of the surface, and the specific type of oil/grease can influence the intensity of the stain.

Identifying the Stain

• Fresh stains can appear as dark spots of patches and the area might have a darker or glossy appearance.
• As the oil/grease penetrates deeper into the pores, the stain can become more prominent and spread out, creating a darker brown/black coloration, irregular shape, and greasy texture.

How to Remove Oil & Grease Stains

The success of stain removal depends on several factors, including the age of the stain, the type of oil or grease, and the porosity of the surface. Older stains are generally more deeply embedded in the porous material, making them more difficult to remove compared to fresh stains. However, with the right cleaning methods and products, it is often possible to significantly reduce the appearance of old oil and grease stains. There are several approaches you can try...

Degreasers

‍Use commercial degreasing agents specifically designed for concrete and pavers. These products help break down the oil and grease, making it easier to lift the stain.

Absorbent Materials

‍Sprinkle absorbent materials like kitty litter, baking soda, or sawdust on the stain to soak up as much oil or grease as possible. Let it sit for a while and then sweep it away before cleaning the area further. This is most effective on fresh stains.‍

Pressure Washing

‍High-pressure washing can help dislodge and remove surface-level stains. Do not use too much pressure, as it could damage the pavers or concrete.‍

Chemical Solvents

‍In extreme cases, you may need to use chemical solvents or poultices specifically designed for removing stubborn oil and grease stains.
