Grease and fat stains on concrete can be caused by a variety of factors, including:
- Oil leaks from vehicles
- Food and cooking spills
- Industrial accidents
- Poor cleaning and maintenance practices
The Importance of Prompt Action
The key to removing grease and fat stains from concrete is to act quickly. The longer you wait, the more time the stain has to set, making it increasingly challenging to remove. If you notice a grease or fat stain on your concrete, don’t delay – start the removal process as soon as possible.

How do I identify the type of grease or fat stain on my concrete?
Identifying the type of grease or fat stain on your concrete is crucial in determining the best removal method. There are several types of grease and fat stains, including food-based, petroleum-based, and mechanical-based stains. Food-based stains typically come from spills or splatters of cooking oil, grease, or food residue. Petroleum-based stains come from motor oil, gasoline, or other lubricants. Mechanical-based stains come from machinery or equipment leaks.
To identify the type of stain, examine the color and consistency of the stain. Food-based stains tend to be darker and more viscous, while petroleum-based stains are typically lighter and more translucent. Mechanical-based stains can range in color and consistency. You can also perform a simple test by applying a small amount of solvent, such as mineral spirits or acetone, to the stain. If the stain dissolves, it’s likely petroleum-based. If it doesn’t dissolve, it may be food-based or mechanical-based.
