Thank you for leaving a review. It is very common for griddles to expand and contract during heating and cooling, and in some cases with thermal shock the griddle can warp or pop-up temporarily, but will correct itself. This is likely to occur in the first couple months of use but will correct itself with continued use. You can reduce the impact by only placing room temperature foods on the griddle, never placing food right from the fridge or freezer onto the surface, and also not pouring water on the surface for cleaning.All Member’s Mark items carry a 100% member satisfaction guarantee .

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 and must be repeated. Unfortunately, seasoning is not a single application. 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. 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 re-seasoning. For your convenience, I've included a link below to a step-by-step instructional video for how to season your griddle once the rust has been lifted:https://www.youtube.com/watch?v=2MIDadWvHmkFor further assistance, feel free to contact us at 1-833-454-0864 or support@proseriesbbq.com.
