I must try this with my GF...Right after using the grill, unplug it and place a wet double-sheet of paper towel between the lid and the surface. The leftover heat causes the towel to steam and clean the grill. Wiping it dry with another paper towel is all that’s needed. I'm going to try with waffle iron.
So remembering this for whenever I have to caulk anything again: using an ice cube: The caulk will not stick to the ice, and the ice will melt to the shape of the joint to become the perfect shaped tool. Thanks Apartment Therapy!
