You can unplug it when you're finished making your waffles, and it can cool while you eat. Remove the plates from the waffle iron according to the manufacturer’s instructions, if you still have them. Waffle iron grid plates usually snap out easily. Allow the water to remove any remaining crumbs. It's great to turn the plates vertical so that the water can run through the ridges, rinsing spots you may have missed with your sponge, brush, or rag. The dishwasher can be damaging to the nonstick surface of the waffle iron, so this method is the next best thing. Check your manufacturer's instructions to see if your plates can go in the dishwasher or not.
