Looking for an unusual father’s day gift? Surprise dad by cleaning ugly grease and oil stains off the driveway and garage floor. Here’s how to remove spots before one's very eyes. First, sprinkle cat litter on the greasy oil stains. Then, grind it in by twisting around on it. Sweep it up, and open a can of cola. Pour the soft drink on the floor. Wet the stains thoroughly and work the litter and cola it in with a stiff broom, but don’t let it dry. When it quits fizzing, rinse with water. Scrub any trace stains with a cup of bleach and a cup of laundry detergent in a gallon of very hot water. It works. Now tell dad to close his eyes and come on in. And that's the On The House tip for today.
