Many home mechanics have changed the oil in their car or fixed a broken lawn mower on top of the garage floor or concrete drive way. These do-it-yourself fixes will save a few bucks, but will also leave behind unsightly grease stains. If this is a familiar scenario at your home look no further than the refrigerator to find an inexpensive way to remove these stains: Coca Cola. The acids in the soda will safely and effectively loosen the grease stains, allowing them to be washed away.
Pour cat litter over any new grease stains and allow the litter to soak up the grease for 30 minutes. After the time has elapsed, shovel the cat litter and pour it into a sturdy garbage bag. If the stain is older, skip this step.

Pour one 12 oz. can of Coca Cola onto the stained area. Work the Coke into the stain with a nylon scrub brush. Avoid using a wire brush on the concrete, as this will lead to noticeable scratches. Use more than one can of Coke if the stain is larger. Use a lesser amount if the stain is smaller.
Allow the Coca Cola to remain on the stain for 30 minutes.
Prepare a mixture of 1/2 cup laundry soap, 1/4 cup liquid bleach and 1 gallon of water in a plastic bucket.
Dip a mop into the bucket and, with rubber gloved hands, wring out the excess liquid until the mop is damp, not soaking wet.
Mop away the Coca Cola from the previously stained area. If there is any stain remaining, repeat the process of covering it with Coke, allowing the cola to sit and mopping it away with the bleach mixture.
