1 cup all-purpose flour
1 cup cornmeal
Mix the ingredients and pour them into a container roomy enough to hold the pet - a large paper box for a big pet or a deep roasting dish for a small pet will work.
Place the container filled with the mixture in the bathtub and gently place your pet into the pan or box. Rub the mixture, by handsful, into your pet's fur until all the goo or oil or mess has been absorbed. Gently brush the mixture out of the fur. Be careful to keep the mixture out of your pet's eyes, nose and ears. Dispose of the used mixture. It's a good idea to follow up with a regular mild shampoo at this point if you can manage it.
