How do you clean a concrete floor?
To pick up the dust and dirt, sprinkle slightly damp coffee grounds over the surface, then sweep. Or you can scrub with a mixture of 1 cup laundry detergent, 1 cup household (5 percent) bleach, and 1 gallon cold water (multiply the amounts as needed), then rinse. To clean grease and oil from concrete, sprinkle TSP (or another product containing trisodium phosphate) over the area, add a little hot water to make a paste, and scrub vigorously with a stiff-bristle brush. Wear rubber gloves to protect your hands. Let sit for 20 minutes, then rinse with hot water. Repeat if necessary. Oil also can be removed by soaking the stain with paint thinner for about 20 minutes. Then scrub with a stiff-bristle brush as you add more paint thinner. Cover the stain immediately with fresh cat litter or dry sawdust. When the litter or sawdust has absorbed the oil, vacuum it up. Repeat if necessary.
