Removing antifreeze from concrete requires water, laundry detergent, newspaper and a stiff nylon-bristled brush. Test the cleaning agent in an inconspicuous spot to make sure it will not damage the concrete. The cleaning process takes about 3 hours.
Use a water hose or other watering device to soak the concrete stained with antifreeze. Because antifreeze is water soluble, applying water helps to break it up and remove the stain.
Open a box of powdered laundry detergent, and sprinkle it over the stain, applying until the stain is no longer visible. Cover the laundry detergent with a thick layer of newspaper. Wet the newspaper, and allow it to sit for 3 hours.
Remove the newspaper from the stain, and discard it. Using the nylon-bristled brush, scrub the moist laundry detergent, creating a paste. Scrub until suds form.
Rinse the brush and the concrete with water. Pat the concrete with clean newspapers, blotting up any remaining fluid. Allow the concrete to air dry.
Inspect the concrete for additional staining, and repeat the process as needed until you have completely removed the antifreeze.
