Nylon scrub brush
Grease is a common element that spills onto concrete surfaces, whether it be food grease on a patio or car grease on a driveway. Concrete works well when it comes to weathering and outdoor elements, but grease stains can quickly soil the concrete surface and leave behind residue that is difficult to remove. To get rid of the grease, use baking soda, which naturally draws out the grease residue without harming the concrete.
