3. Use a grease-cutting cleanser to remove any oil or other contaminants around the repair area that might prevent the concrete filler from setting up properly. Sweep up all the debris around the area, being sure not to sweep dust back into the cracks. Finish cleaning by vacuuming out the cracks with a workshop vacuum.
