Combine 1 cup hot water with 2 tbsp. liquid dishwashing detergent. Pour over a cooled stovetop griddle and let it soak for one hour.
Use a dishcloth or a plastic scrubber to wash the griddle.
Create a paste of 1/2 tsp. baking soda and 1/2 cup water if there are stubborn sticky parts. Rub the paste with a dishcloth or plastic scrubber over the sticky spots until they disappear. Dry the griddle with a clean towel.
