1 16-ounce box (454g) baking soda
1 16-ounce box (454g) corn meal
If you car is leaking a little oil, you’re most likely to see the evidence on your garage floor or driveway. Fortunately, the cleanup will be easy (and cheap) to tackle with this formula-unlike the leak itself. Mix the baking soda and cornmeal in a large plastic container (the amounts here should be enough for several spills). Sprinkle lightly on a fresh spill to soak it up. Let dry overnight, then sweep or use a shop-vac to get rid of it in the morning.
