Do your driveway and garage floor look like an ad for grease? If so, it's time for one of the Carey family formulas for cleaning greasy stuff. First, grab some cat litter and spread it around on the grease. Then grind it in real good, walking and twisting around on it. Sweep it up, and open a cola beverage. Spread the drink around on the floor. Wet the grease stains thoroughly. Work it in with a stiff broom, but don't let it dry. Once the cola quits fizzing, rinse it with water, then whiten up the remaining gray stain with a solution of 1 cup of liquid chlorine bleach and 1 cup of powdered laundry detergent in 1 gallon of very hot water. And that's the On The House tip for today.
