Sterilize Your Dish Cloth or Sponge/Clean Your Microwave
Bacteria collects in your dish cloth or sponge and the best way to sterilize it is to put the very wet cloth or sponge in your microwave oven, run it for 2 minutes and remove carefully with tongs or oven-glove. While the microwave oven is still steamy, wipe it dry with a clean dish towel.
