Step 1
Mix 1 qt. of water with 1/4 cup of white distilled vinegar, if this is the first time this griddle is to be cleaned. Vikingrange.com suggests using a scrubbing pad to scrub this solution over the griddle.
Step 2
Dry the griddle with a towel after initially cleaning the griddle with the water and vinegar. Next, wash it with soapy water (you can use a sponge soaked in 1 tsp. of dish detergent in a bowl of warm water). Rinse it with clean, warm water and dry with a towel.
Step 3
Season your griddle after the initial cleaning. Vikingrange.com suggests using a cloth to apply 1 tsp. of vegetable oil (unsalted). Allow the oil to sit for an hour and then wipe off excess with a clean cloth.
Step 4
Clean your griddle with club soda, as suggested by vikingrange.com, after heavy use (for example, after cooking very greasy items or if food is stuck to the griddle). To do so, pour the club soda slowly onto the griddle. The griddle should still be slightly warm and the soda should be room temperature--not cold. Use a spatula to push debris toward the grease trap--soap and water is not necessary for everyday cleaning.
