Household "Dawn" cuts grease.
You can clean the engine grease and the cooking kettle

all with one product.
Check out this story from a 1998 Newspaper:
* Along I-74 near Cincinnati where an overturned tanker truck spilled 20,000 gallons of animal fat on the pavement, NOTHING could get up the 2-inch-thick layer of congealed waste until Cincinnati-based Procoer & Gamble Co., came through by donating 3 tons of Dawn, the grease-fighting dish-washing liquid. "This was by far our most extreme case of grease buildup," said a company spokesman.
