Thank you for taking time to leave a review. Your tip regarding always using of the griddle cover between uses (when the griddle has cooled) is 100% correct for the longevity of your griddle. Please note that a layer of seasoning before and after each use, will also help protect the griddle top from rust and deterioration. Hope this helps!

Thank you for taking time to leave a review. The appearance of rust spots on the griddle top, is indication that the protective seasoning has worn off. Good news is that the griddle top can be fully restored! Begin by dampening the surface with water. With protective gloves and steel wool, scrub the areas of concern until the rust has been lifted from the surface. Rinse the surface thoroughly. (Be careful not to overflow the grease catch.) Wipe the griddle surface with a cloth to dry, and remove any debris before seasoning. For your convenience, I've included a link below to a quick start video that includes step-by-step instructions for how to season your griddle once the rust has been lifted: https://www.youtube.com/watch?v=2MIDadWvHmk Seasoning your griddle top is required before and after every cook. Seasoning your griddle top improves the cooking performance, creates a non-stick surface, prevents damage, and deterioration due to moisture, and extends the life of your griddle.
