wish I knew this years ago- 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.
Punch a hole in the top of a bottle of vinegar and sit the bottle in your toilet tank. In doing this you will save water, as the tank wont fill as much, the vinegar will clean your toilet AND tank on each flush, it leaves the bathroom smelling fresh and it doesn't harm any component of your toilet OR the environment when flushed.
