Coffee grinder cleaning trick: Run a small handful of uncooked white rice through the coffee grinder, especially if you use it for grinding anything other than coffee beans. Most coffee experts advise against using your machine for grinding dry spices since the smells from grinding ingredients, such as cinnamon sticks and dried basil, are nearly always impossible to get out.
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.
