A degreaser is a cleaning agent that is used to remove grease and oil from surfaces. Degreasers can be used on a variety of surfaces, including concrete.
Concrete is a porous material, which means that it can absorb grease and oil. This can make concrete difficult to clean, and it can also lead to the growth of mold and mildew. A degreaser can help to remove grease and oil from concrete, making it easier to clean and maintain.
