Seasoning the Griddle Before a new griddle is used, it must be seasoned to prevent permanent discoloration and staining.
1. Clean the griddle thoroughly with hot, soapy water to remove any protective coating.
2. Wipe the surface using a solution of 1 quart water and 1 cup white vinegar. Dry thoroughly.
3. Brush 1 tablespoon vegetable shortening evenly across the griddle. Do not use corn oil as it can get sticky.
4. Turn the control knob to 350F for approximately 30 minutes. Turn the heat off when the oil begins to smoke. Allow the griddle to cool.
5. Repeat Step 3. Be sure to cover the entire surface with the shortening.
6. Repeat Step 4. Allow the griddle to cool. Wipe the entire surface of the griddle using a heavy cloth. Brush the surface with a very thin layer of shortening. The griddle is now ready to use.
