I second the doggies! I make my own hand/face creams & this is my trick in cleaning that greasy mess up. It even works with beeswax so it should do just fine with regular animal fat. Wipe with a dry paper towel or dry cloth towel first. Then don dish gloves (yes, this is important!) and use liquid AUTO dish detergent in the sink with very hot water (another reason for the gloves). I use Trader Joe's brand, too, not too expensive or smelly (I don't like smelly stuff).
